Place the AP far away from electronic devices that may produce radio interference, such
as microwave ovens, other APs, antennas, and other radio communication devices. For
details, see Table 2-2.
Install the AP in a hidden position that does not affect daily lives and work of residents.
Install the AP in a site that is free from leaking or dripping water, heavy dew, and
humidity, and take protective measures to prevent water from flowing into the equipment
along the cable.
Do not install the AP in an environment with high temperature, dust, poisonous gases,
flammable or explosive objects, electromagnetic interference (from a radar station, radio
station, or substation), unstable voltage, violent shakes, or strong noise.
Table 2-2 General anti-interference requirements
Scenario
Deployment Distance Requirement
Indoor
installation
There should be at least a 7 m distance between antennas.
The antennas should be placed at least 2 m from the 4G antennas of
the carrier.
The antennas should be placed far away from electronic devices that
may produce interference, such as microwave ovens.
If antennas are embedded into APs, the deployment distance requirements on the antennas are those on
APs.
2.5 Installing an IoT Card
The AP provides an IoT slot for installing an ANT or RFID card based on customer
requirements.
1. Hold the buckle on the bottom cover of the AP, and remove the cover and plastic plugs.
The number of rubber plugs to be removed depends on the number of radio cables.
Use a flat-head screwdriver to remove the cover. Insert the flat-head screwdriver under the cover buckle
and lever the buckle.

Network cable
The service network cable and PoE input cable cannot
be connected to the console port. Otherwise, the AP
may be damaged when using PoE power supply.
If the AP needs to connect to the Ethernet, ensure that
the Ethernet cable is working properly. If the Ethernet
cable is not working properly, for example, RJ45
connectors are short-circuited, the AP may fail to be
powered on or fail to work. Before connecting an
Ethernet cable to the AP, use the cable test tool to
check whether the cable is qualified. If the cable is
unqualified, replace it.
For the supported network cable types and length
requirements, see Connecting Network Cables.

No priorities are distinguished for DC and PoE power supply modes, DC and GE/PoE_IN support
HSB.
Two PoE channels have no priority and can serve as HSB for each other when they have the same
input power type.
When installing a cable, you must make a drip loop to prevent water from flowing into
devices along the cable. For the method of making the drip loop, see 5.8 Guide to Making
Drip Loops.
Pay attention to the following points when bundling the cables:
Different types of cables must be separately routed with the minimum spacing of 30 mm
and cannot be entangled or crossed. Cables should be parallel or separated using
dedicated separators.
Bundled cables are closely arranged, straight, tidy, and undamaged.

Connecting UTP network cables to 5GE interfaces poses high risks and is not recommended. The
causes are as follows:
802.3bz requires that the ALSNR value for alien crosstalk between network cables be greater than 0,
but the standards for Cat5e and Cat6 unshielded twisted pairs do not specify the required ALSNR
value. Therefore, such cables may not meet the crosstalk requirement in 802.3bz, causing severe
problems such as continuous packet loss.
According the cabling specification TIA TSB-5021, using Cat5e and Cat6 cables for 5G poses high
risks.
Currently, no clear onsite testing or evaluation method is available for checking whether ALSNR of
cables conforms to 802.3bz.
If Cat5e and Cat6 unshielded twisted pairs do not meet the 5G requirement, you are advised to
replace them with shielded twisted pairs or reduce the rate of interfaces to 2.5G.
Connecting Antennas
Connect the antennas delivered in the installation accessory package of the AP to the 2.4G/5G
RF ports on the AP, tighten the nuts (with a torque of 0.8 N•m), and adjust antenna angles as
required.
Do not connect the antennas delivered in the installation accessory package of the AP to 5G antenna
interfaces. Otherwise, the AP and antennas may be damaged. The 5G antenna interfaces can be
connected only to remote antennas through feeder cables.
2.8 Connecting the Security Lock
There is a security slot on the device. You can lock the device to an immovable object to
prevent theft. The detailed procedures are as follows:
1. Fasten the cable of the security lock to an immovable object around.
2. Insert the security lock into the security slot and lock it.

Checking the Appearance of Cables
If the cable jacket or insulation is visibly dirty, clean it before assembly.
If the jacket or insulation of a cable has visible damage, irreparable scuffing, or other
defects, do not use the cable.
If the shield layer of a cable is damaged, do not use the cable.
If the cable jacket or insulation cracks after the cable is bent or twisted, discard this cable
and check whether other cables have the same problem. If other cables have the same
problem, replace these cables.
Checking the Appearance of Connectors
Do not use connectors with visible defects, damage, rust or scuffing.

Do not use connectors if their shells or pins have exposed part or uneven plating, or their
pins are lost, broken, or bent.
Do not use connectors that have dirt on their pins or in their jacks or if there are
conductors between pins or between pins and the shell.
Precautions for Assembly
Use dedicated tools or tools delivered by Huawei and follow the methods given here
during assembly.
Hold terminals of cables instead of pulling the cables themselves when installing or
removing cable components.
Take the following precautions when cutting or stripping cables:
− Make cables slightly longer than necessary.
− Coil cables longer than 2 m (6.56 ft) after cutting. Bind and fasten the coils using
bundling ropes. The inner diameters of the coils should be larger than 20 times the
outer diameters of the cables.
− When stripping the jackets of cables, avoid damaging the shield layers (braid or
aluminum foil), insulation, core conductors, and other jackets that do not need to be
stripped.
− After assembling cables, cut all visible cross sections of jackets to ensure that the
cross sections are arranged neatly.
− Do not touch the core conductors of cables with your hands. Terminate exposed
conductors in a timely way after stripping off insulation so that the surface of the
conductors does not become oxidized.
Take the following precautions when crimping and connecting cables or connectors:
− The terminals and conductors should be connected tightly after they are crimped.
They should not be moved or turned.
− Cut all the exposed copper wires.
− Try to avoid a second crimping of sleeves.
− Keep all the conductors clean and aligned.
The connectors, cables, and tools provided by different vendors may be different. The figures in this
document are for your reference only.

5.1.3.6 Checking the Appearance of Contact Strips
Context
To ensure proper contact between the crimped wires and the wire conductors, the heights
and sizes of the contact strips must be standard and the same.
The contact strips must be parallel to each other, with an offset of less than ± 5°. The top
margin of a strip must be parallel to the axis of the connector, with an offset of less than
± 10°.
To ensure conductivity, the surface of the contact strips must be clean.
The contact strips must be in good contact with the RJ45 socket. The plastic separators
must remain intact and be aligned.
The contact strip blade must extend beyond the ends of the wires. The ends of the wires
must be in contact with the edge of the RJ45. The distance between them must be less
than 0.5 mm (0.02 in.).
Procedure
Step 1 Hold the crimped connector, with the front side facing you, and check whether the contact
strips are of the same height. The height should be 6.02 ± 0.13 mm (0.237 ± 0.005). If a
measuring tool is not available, you can compare the connector with a standard connector.
Figure 5-79 shows an unqualified piece, and Figure 5-80 shows a qualified piece.

Procedure
Step 1 Feed both connectors of the cable into the ports of the cable tester.
Step 2 After the connectors are properly inserted, turn on the tester. If the indicators from 1 to G turn
on simultaneously, you can infer that the pins work normally and the wires are correctly
connected.

Figure 5-87 Checking the reliability
The procedure for testing a crossover cable is the same as that for testing a straight-through
cable except for the sequence in which the indicators turn on, which depends on the wire
connections of a crossover cable.
The Ethernet cable is qualified if the indicators turn on in the following sequence:
At the master (left) section of the tester, the indicators turn on in the sequence of 1-8-G. At the
slave (right) section of the tester, the indicators turn on in the sequence of 3-6-1-4-5-2-7-8-G.
If the indicators do not come on in this sequence, the Ethernet cable is unqualified.
If a tester is not available, you can use a multimeter to perform a simple test, as shown in Figure 5-88.

5.1.3.8 Common Network Cable Faults and Preventive Measures
Table 5-12 lists common network cable faults and preventive measures.
Table 5-12 Common network cable faults and preventive measures
Symptom
Cause
Preventive Measure
The device cannot be
powered using PoE.
The device restarts
frequently.
A large number of error
packets exist on the
device or services are
interrupted.
A network cable has high
resistance or is too long.
Before using network cables
purchased from other
suppliers, use a multimeter
or other tools to measure
cable resistance. If the
resistance of a network
cable does not comply with
the quality requirement of
the PoE standard, as shown
in Table 5-13, replace the
network cable.
Non-standard network cable
connectors cause poor
contact with device
interfaces.
Before making a network
cable, use a standard go-no
go gauge to test the
connectors purchased from
other suppliers. Replace the
connectors if they do not
comply with the standard.
Wires in a network cable are
connected to wrong pins.
After a network cable is
made, use a conduction
tester to measure cable
connectivity. For test
details, see 5.1.3.7 Testing
the Connection of
Assembled Cables.
A network cable connector
is not crimped securely,
causing poor contact
between the network cable
and pins in the connector.
When testing a network
cable with a conduction
tester, gently shake the cable
connector and check
whether indicators on the
conduction tester are in
normal state. If indicators 1
to G turn on in a wrong
sequence, remake the
network cable.
The following methods are often used to test network cable resistance, and the test criteria are
listed in Table 5-13:
Use a network cable tester (high-end cable tester of Fluke) to measure network cable
resistance.

Connect multimeter probes to two ends of each wire in a network cable and check the
resistance value on the multimeter.
Connect a network cable to an AP. Use a multimeter to test the resistance between pins 1
and 2 (or between pins 3 and 6, 4 and 5, or 7 and 8) on the other end of the cable. The
cable's DC resistance approximately equals a half of the displayed value.

5.1.5 Installing Cable Accessories
5.1.5.1 Precautions for Installing Cable Accessories
Tools
The illustrations in this document may differ from actual situations, but the installation methods are the
same. For example, in this document, the adapters of cable connectors have separate interfaces. In the
actual situation, the adapters may have interfaces fixed on equipment.
Use dedicated tools provided or specified by Huawei and follow the installation procedure
described here.
Bending Radius
Unless otherwise specified, bending radius (R) of cables or fibers must meet the requirements
listed in Table 5-14.
Table 5-14 Bending radius of cables or fibers
Cable or Fiber
Bending Radius (R)
Ordinary cable
In normal cases, R ≥ 2d. When the cable is
connected with a connector, R ≥ 5d.
Fiber
R ≥ 40 mm (1.57 in.); Bending angle > 90°
The letter d indicates the diameter of a cable or fiber.
Precautions for Installation
Hold terminals of cables instead of pulling the cables themselves when installing or
removing cable components.
Do not insert a connector forcibly when the connector is blocked. Use a dedicated tool to
pull out the connector. Install the connector again after you check that the pins are
inserted properly.
Before tightening screws on cable connectors, ensure that the connectors are properly
connected to their adapters. Tighten the screw with appropriate force using a flat-head or
Phillips screwdriver instead of bare hands or an electric screwdriver. If the screw cannot
be screwed into the tapped hole, determine the reason and try again. Do not apply too
much force, or the screw or adapter may be damaged.
When removing densely aligned cables or fiber connectors, use dedicated pliers such as
cable-pulling pliers and fiber-pulling pliers.
Do not twist, bend, stretch, or extrude fibers during installation.
Cover the idle fiber connectors with dust caps. Remove the dust caps before using the
fiber connectors.

Requirements for Cable Routing
To protect cables, remove the burrs in the cable through-holes or install protective rings
in the holes.
To ease the connection and to avoid stress, keep cable joints slack. After connecting
multiple cables to a connector that has multiple interfaces, keep the cables slack to avoid
generating stress.
Bind or clean cables gently because cable distortion affects signal quality.
Keep cables away from moveable components such as doors.
Sharp objects must not touch cable wiring to prevent damage to cables.
To protect power cables, route power cables of the active and standby power modules
separately.

requirements of the equipment. Also consider hydrographic, geological, seismic, power
supply, and transportation factors.
Construction, structure, heating and ventilation, power supply, lighting and fire-proof
construction of the equipment room should be designed by specialized construction designers
to suit the environmental requirements of devices. The equipment room should also follow
local regulations concerning the industrial construction, environmental protection, fire safety,
and civil air defense. Construction must conform to government standards, regulations, and
other requirements.
The equipment room should be located in a place free from high temperature, dust, toxic
gases, explosive materials, or unstable voltage. Keep the equipment room away from
significant vibrations or loud noises, as well as power transformer stations.

sources such as smelting and coal mines. It should be located at a distance of at least 3.7
km (2.30 mi.) from moderate pollution sources such as chemical, rubber, and
galvanization factories. It should be located at a distance of at least 2 km (1.24 mi.) from
light pollution sources such as packinghouses and tanyards. If these pollution sources
cannot be avoided, ensure that the equipment room is upwind of the pollution sources. In
addition, use a high-quality equipment room or protection products.
The room should be located away from livestock farms, or be upwind of the livestock
farms. Do not use an old livestock room or fertilizer warehouse as the equipment room.
The equipment room must be far away from residential areas. An equipment room that is
not far away from residential areas must comply with equipment room construction
standards to avoid noise pollution.
The room should be located far away from industrial and heating boilers.
The room should be at least 3.7 km (2.30 mi.) away from the seaside or salt lake.
Otherwise, the equipment room should be airtight with cooling facilities. In addition,
alkalized soil cannot be used as the construction material. Otherwise, equipment suitable
for wet conditions must be used.
The doors and windows of the equipment room must be kept closed to maintain an
airtight room.
Using steel doors to ensure sound insulation is recommended.
No cracks or openings are allowed on the walls or floors. The outlet holes on the walls or
windows must be sealed. Walls must be constructed such that they are smooth,
wear-resistant, dustproof, flame retardant, sound insulated, heat absorptive, and have
electromagnetic shielding.
The air vent of the room should be far from the exhaust of city waste pipes, big cesspools
and sewage treatment tanks. The room should be in the positive pressure state to prevent
corrosive gases from entering the equipment room and corroding components and circuit
boards.
It is recommended that the room be on or above the second floor. If this requirement
cannot be met, the ground for equipment installation in the room should be at least 600
mm (23.62 in,) above the maximum flood level.
The equipment room should be strong enough to resist winds and downpours.
The room should be located away from dusty roads or sand. If this is unavoidable, the
doors and windows of the equipment room must not face pollution sources.
Do not place air conditioning vents near the equipment so that they blow directly on the
equipment because condensation may be blown into the equipment.
Do not use decorative materials that contain sulfur in the equipment room.

This AC power supply should be 110 V/220 V, with a frequency of 50 Hz.
The UPS should supply the same power and operate at the same phase as the power mains.
The switching time between the UPS and mains should be less than 10 ms; otherwise, the
networking devices will reboot or reset.
For power distribution capacity in the equipment room, both the working current and fault
current of the devices should be considered. Ensure that independent AC power supplies
protect independent devices. Configure the current-carrying capacity of the protection switch
of the equipment room for more than that of the devices.

The automated electric generator must have a standard interface that supports
telecommunication protocols, remote telecommunication, monitoring, and control.
AC power cables should meet the following specifications:
AC neutral should have a conductor with the same cross section as the phase line.
AC cables should have non-flammable insulation. The layout of AC cables should
comply with local regulations. Low-voltage power distribution rooms should comply
with local regulations.
5.2.2.2 Recommendations for AC Power Supply
The following are recommendations for the AC power supply.
If the voltage of the power mains that supply power directly to devices exceeds the rated
voltage by -10% to 5%, or exceeds the voltage range that devices can support, a voltage
regulating device or voltage stabilizing device is required.
If the mains do not supply power for the device directly, or if the mains voltage exceeds
the rated voltage by -15% to 10% or exceeds the input voltage range of the DC power
supply, a voltage regulating device or voltage stabilizing device is required.
A UPS or inverter power supply system is required to provide uninterrupted AC power to
support the telecommunication load.
If abnormalities occur on the mains, telecommunication servers should be equipped with
a self-supplied electric generator to support the key telecommunication load. The
capacity should be not less than 150% to 200% of the total uninterruptible power supply.
Storage batteries are usually installed in a parallel connection of two groups. UPS
storage batteries are generally installed in one group. The redundancy required for the
UPS can rely on concatenation or parallel connection. When an inverter or a UPS is used,
the active inverter is determined by the maximum power and a backup inverter is
required.
5.2.2.3 Requirements for DC Power Supply
The equipment room should receive stable and reliable DC power. Deploy the power
equipment near the telecommunications equipment to make the DC feeder as short as possible.
To reduce power consumption and installation cost, the loop voltage drop from the battery
port to the equipment port should be less than 3.2 V.
A large-scale enterprise can deploy an independent power supply system on each floor to
supply power to the telecommunications equipment room on the respective floor.
A medium-scale enterprise can use a power room and a battery room for centralized
power supply or use distributed power supply systems.

The following are recommendations for the DC power supply.
Use distributed power supply mode. Use multiple DC power supply systems and put
power equipment in multiple locations.
Adopt a standard DC power supply system, and set the output voltage to the
communications equipment within the required range.
Improve reliability of the AC power supply system to reduce the necessary capacity of
storage batteries. For small offices, increase the capacity of storage batteries if it is
difficult to enhance reliability of the AC power supply system.
The total capacity of the high-frequency switching rectifier must satisfy the power of the
communication loading and battery charging. If there are 10 or fewer active rectifier
modules, configure one backup module. If there are more than 10 active modules,
configure one backup module for every 10 active modules.
Install storage batteries in two or more groups. The capacity is determined by the
duration for which the storage batteries must supply power. For most offices, the
batteries should be able to supply power for at least one hour.

Figure 5-154 Label for signal cables
To specify more clearly the position of a cable, use the dividing lines on the label. For
example, there is a dividing line between the cabinet number and the chassis number, and
another one between the chassis number and the slot number. Each dividing line is light blue
(Pantone 656c) and 1.5 mm x 0.6 mm (0.06 in. x 0.02 in.).
The cut dotted line helps to fold the label when affixed to the cable, and its size is 1 mm x 2
mm (0.04 in. x 0.08 in.).
The word "TO:" (upside down in the figure) at the lower right corner of the label is used to
identify the opposite end of the cable on which the label is affixed.

Requirements for Feeding the Printer
The label paper consists of two layers and has undergone multiple processing procedures such
as printing and cutting. No matter what model of printer you use, feed in the labels one page
at a time. To avoid jamming the labels, never use the auto-feed mode.
Feed in the label paper in the correct direction to ensure that the text is printed in a correct
position.
Requirements for the Printed Label
Make sure that the printed labels satisfy the following requirements:
All the printouts must be on the label, and nothing should be printed on the backing layer
of the label page.
Contents in the cells should be aligned in the center. In a single-line printout, the
dividing lines and the word "TO:" should not be covered by printed characters.
When the cells are merged and the printouts are made in multiple lines, avoid covering
the word "TO:" when printing the text. Use the space bar to move the text to the next
line.
5.4.1.4 Writing Labels
Writing Tools
To make sure the printouts are clear and legible, use black markers instead of ball-point pens
to write the labels.
If no marker is available, black ball-point pens are allowed, although not recommended.
Compared with ball-point pens, waterproof markers are better. When writing with a ball-point
pen, do not leave the oil on the label, which may contaminate the label and blur the words.
The delivered marker has two nibs. Use the smaller nib to write the labels.
Font
For the sake of legibility, use standard block letters and numbers as shown in Table 5-26
(Times New Roman).

5.4.1.6 Contents of Engineering Labels
Contents of Labels for Power Cables
Labels for power cables are affixed on only one side of the identification plates. On the labels,
there is information (the part after the word "TO:") about the location of the device on the
other end of the cable, like the location of control cabinet, distribution box or power socket.
Contents of Labels for Signal Cables
The two sides of the label affixed on the signal cable carry information about the location of
the ports connected to both ends of the cable. Figure 5-161 shows the information on both
sides of the labels affixed to the signal cables.
Area 1 contains the location information of the local end of the cable.
Area 2 (with the word "TO:") contains the location information of the opposite end of the
cable.
Area 3 has been folded up inside the label.
Figure 5-161 Printed parts on the label for signal cables
Seen from the cabling end of the equipment, the text part of the label is on the right side of the
cable. The side with "TO:" that is facing outside carries the location information of the
opposite end; and the other side carries the location information of the local end.

In other words, the information in Area 1 at one end is the same as the information in Area 2
at the other end of the cable.
5.4.1.7 Precautions for Using Engineering Labels
When using labels, pay attention to the following points:
When printing, writing, or attaching labels, keep the labels clean.
Since the label paper is made of moistureproof material, ink-jet printers and ink pens
cannot be used to print and write labels.
Labels should be attached neatly. New-type labels are L-shaped. If they are pasted at
incorrect locations or in the incorrect direction, the appearance of the device is affected.
Power cable ties should be attached in the same positions on power cables, with
identification plates on the same side.
The positions of "up", "down", "left" or "right" are all based on the viewpoint of the
engineering person who is working on the label.
5.4.2 Engineering Labels for Optical Fibers
These labels are affixed to the optical fibers that connect the optical interfaces on the boards
in a chassis, or on the device boxes. There are two types of labels for optical cables:
One is for the fiber that connects the optical interfaces on two devices.
The other is for the fiber that connects the device and the ODF.

5-31 lists the information on two -48 V power supplies on the label. The information on other
DC voltages, such as 24 V and 60 V should be given in similar methods.
Make sure that labels are affixed in the correct direction. That is, after the cable ties are
bundled onto the cable, the identification plates with the labels should face up, and the text on
the labels in the same cabinet should be in the same direction. For details, see Figure 5-166.
Figure 5-166 Example of the labels for DC power cables
The meaning of the label in Figure 5-166 is as follows:
On the loaded cabinet side, the label "A01/B08--48V2" on the cable indicates that the
cable is -48 V DC supply, which is from the eighth connector in row B of -48 V bus bar
in the cabinet in row A, and column 1 in the equipment room.
On the distribution box side, the label "B03--48V2" indicates that the cable is -48 V DC
supply, connected to DC power socket 2 in row B, column 03 in the equipment room.
In the power distribution box or the first power cabinet of a row in a transmission equipment room,
every terminal block on the -48 V connector bar has a numeric identification. For example, in the above
label of "A01/B08--48V2", "08" (or sometimes "8") is the numeric identification of the terminal block.

PGND and BGND are two copper bars, on which the terminal blocks are short-circuited.
Therefore, it makes no difference which terminal is connected to them. It is only necessary to
give the row and column of the power distribution box, instead of giving the specific serial
number of the terminal block on the copper bar. For example, if the label on the loaded
cabinet side is "A01-BGND", it means that the power cable is a BGND that connects BGND
copper bar in the power distribution box in row A, column 01 in the machine room.
Information on the labels for PGND cables should be given in a similar way.
5.4.5.2 Engineering Labels for AC Power Cables
These labels are affixed to both ends of an AC power cable that provides AC power supply to
cabinets, including 110/220 V, PGND, and BGND cables. The 110/220 V AC cables and
related PGND and BGND cables are covered with an insulating sheath, so the labels need to
contain only the word "AC" and the cabinet numbers.
The labels for AC power cables are affixed to one side of the identification plates on cable ties.
For details, see Table 5-32.
Table 5-32 Label content
Content
Meaning
MN-(B)-ACn
MN: serial number of the cabinet or the socket where the power is led
in
B: chassis number, numbered in bottom-up order with two digits, for
example, 01.
n: power port number, numbered as 1 to 3 in bottom-up and
left-to-right order.
Serial number of the socket where the power is led in: the location of
the socket is marked according to the actual situation. If the sockets can
be identified by row numbers and column numbers, they can be
numbered following the same rule for the cabinets. If the sockets
cannot be identified by rows and columns, specify the detailed
locations to avoid confusion with other sockets.
The label only carries location information about the opposite equipment and the power
socket; information about the local end is unnecessary.
Make sure that labels are affixed in the correct direction. That is, after the cable ties are
bundled onto the cable, the identification plates with the labels should face up, and the text on
the labels in the same cabinet should be in the same direction, as shown in Figure 5-167.

5.5 Guide to Using Optical Modules
Common Faults of an Optical Module
The system may fail to obtain information about non-Huawei-certified optical modules or obtain
incorrect information. You are advised to use Huawei-certified optical modules. Obtain the electronic
label of the optical module and contact technical support personnel to confirm whether it is a
Huawei-certified optical module.
1. An optical module is not completely installed in position.
If the optical module is not completely installed in position and the latch boss is not
secured, the device cannot identify the optical module. After the optical module works
for a long time, it will be ejected under external stress.
2. The optical receptacle on an optical module is contaminated.
If an optical module is not cleaned or protected properly, contaminants may accumulate
on the fiber pin in the optical module. As a result, the coupling efficiency is reduced,
optical signals are cut off, or even worse, the surface of the fiber pin is damaged
permanently.
3. An optical module is burnt.
If high-power optical signals (caused by an optical time domain reflectometer or
self-loop test) are transmitted through an optical module that is used for long-distance
transmission but no optical attenuator is used, the optical power will exceed the overload
power of the avalanche photodiode (APD). Then the optical module is burnt.
The preceding faults lead to temporary or long-term cut-off of optical signals; or even cause
permanent damages to the optical module, affecting communication services.

Measures to Prevent a Loosened Optical Module
1. When installing an optical module, insert it in position. If you hear a click or feel a slight
shake, it indicates that the latch boss is secured.
If the latch boss is not secured, the gold finger of the optical module is not in good
contact with the connector on the board. In this case, the link may be connected but
optical signals will be cut off or the optical module will be loosened when the optical
module is shaken or hit.
2. Figure 5-168 shows the release handle on an optical module when it is open and closed.
When inserting the optical module, make sure that the release handle is closed. At this
time, the latch boss locks the optical module. After the optical module is inserted, try
pulling it out to see if it is installed in position. If the optical module cannot be pulled out,
it is secured.
Figure 5-168 State of the release handle
Close the release handle Open the release handle
Measures to Prevent Receptacle Contamination
1. Cleaning tissues must be prepared on site. You need to clean the optical connector before
inserting it in the receptacle. This protects the receptacle against contamination on the
surface of the optical connector.
Figure 5-169 Cleaning optical fibers with special cleaning tissues
Place at least three cleaning tissues on the work bench. As shown in Figure 5-169, wipe the end of an
optical connector from left to right or from right to left on a cleaning tissue, and then move the
connector end to the unused part of the cleaning tissue to continue.

2. Cover an unused optical module with a protective cap to prevent dust, as shown in
Figure 5-170.
Figure 5-170 Installing a protective cap
If no protective cap is available, use fibers to protect the optical module, as shown in
Figure 5-171.
Figure 5-171 Using fibers to protect an optical module
3. Cover unused optical connectors with protective caps, as shown in Figure 5-172, and
then lay out fibers on the fiber rack or coil them in a fiber management tray to prevent
fibers from being squeezed.
Figure 5-172 Installing a protective cap on a fiber
4. If a receptacle or an optical connector has not been used for a long time and is not
covered with a protective cap, you need to clean it before using it. Clean a receptacle
with a cotton swab, as shown in Figure 5-173. Clean an optical connector with cleaning
tissues.

Figure 5-173 Cleaning a receptacle with a cotton swab
When cleaning a receptacle, insert the cotton swab and turn it slowly in the receptacle. Do not
use too much strength because the receptacle may be damaged.
5. If optical signals are lost during the operation of a device, use the preceding method to
clean the receptacle or the optical connector. In this manner, the possibility of
contamination can be excluded.
Measures to Prevent an Optical Module from Being Burnt
1. Before using an optical time-domain reflectometer (OTDR) to test the connectivity or the
attenuation of optical signals, disconnect the optical fibers from the optical module.
Otherwise, the optical module will be burnt.
2. When performing a self-loop test, use an optical attenuator. Do not loosen the optical
connector instead of the optical attenuator.
Precautions
1. The optical connector should be vertically inserted in the receptacle to avoid damages to
the receptacle.
2. Fibers must be inserted into optical modules of the corresponding type. That is,
multimode fibers must be inserted into multimode optical modules, and single mode
fibers must be inserted into single mode optical modules. If a fiber is inserted into an
optical module of a different mode, faults may occur. For example, optical signals will
be lost.

5.8 Guide to Making Drip Loops
To prevent water from flowing into devices along cables, you need to take waterproof
measures, for example, create a drip loop on a cable. As an example, the following describes
how to create drip loops on network cables connected to a device in different directions.
When a device is installed in a harsh environment or its ports face upward, follow outdoor
