2 FIBER OPTIC CABLE ROUTING AND INSTALLATION GUIDELINES
The outside plant (OSP) fiber optic cables should be routed between the HU and RU and
terminated before the equipment is installed. A diagram of a typical fiber optic cable routing is
shown in Figure 3-1. At the HU, the OSP cable should be terminated at a fiber distribution panel
and spliced to pigtails. Patch cords may then be used to link the HU optical ports to the OSP
cable terminations. Whenever possible, a guideway such as the FiberGuide system should be
provided to protect the fiber optic patch cords from damage and to prevent excessive bending.
The procedures for connecting the OSP cable optical fibers to the HU is provided in Section 7.
ADCP-75-159 • Issue 1 • August 2003 • Section 3: Host Unit Installation
Page 3-3

Figure 3-1. Typical Fiber Optic Cable Routing
When routed to the RU outdoor cabinet, the OSP fiber optic cable should be spliced to a
connectorized outdoor-rated cable (consisting of individual jacketed pigtails) which is then
routed into the outdoor cabinet. The individual pigtails can then be connected directly to the
STM optical ports. A connector is provided on the bottom of the RU outdoor cabinet to seal the
cable entry point and provide strain relief. The procedure for routing the fiber cable into an
outdoor cabinet and for connecting the pigtail leads to the STM is provided in the Digivance 20
Watt Outdoor Remote Unit Installation Instructions (ADCP-75-148).
When routed to RU indoor mounting shelf, the OSP cable should be terminated at a fiber
distribution panel and spliced to pigtails. Jumper patch cords may then be used to link the STM
optical ports to the OSP cable terminations. Whenever possible, a guideway such as the
FiberGuide system should be provided to protect the fiber optic patch cords from damage and to
prevent excessive bending. The procedure for connecting the OSP optical fibers to an STM
mounted in the indoor mounting shelf is provided in the Digivance 20 Watt System Indoor
Remote Unit Mounting Shelf Installation Instructions (ADCP-75-149).

3 HU MOUNTING PROCEDURE
The HU may be mounted in either a 19-inch or 23-inch EIA or WECO equipment rack. Both
US standard and metric machine screws are included for rack mounting the HU. When loading
the HU in a rack, make sure the mechanical loading of the rack is even to avoid a hazardous
condition such as a severely unbalanced rack. The rack should safety support the combined
weight of all the equipment it holds. In addition, maximum recommended ambient temperature
for the HU is 50º C (122º F). Allow sufficient air circulation or space between units when the
HU is installed in a multi-rack assembly because the operating ambient temperature of the rack
environment might be greater than room ambient.
Use the following procedure to install the HU in the equipment rack:
1. The HU is shipped with the mounting brackets installed for 19-inch rack installations. If
mounting the HU in a 19-inch rack, proceed to step 4. If mounting the HU in a 23-inch
rack, proceed to step 2.
2. Remove both mounting brackets from the HU (requires TORX screwdriver with T20 bit)
and save screws for reuse.
3. Reinstall both mounting brackets so the long side of the bracket is flush with the HU front
panel as shown in Figure 3-2. Use the screws removed in step 2 to re-attach the brackets to
the HU chassis.
Figure 3-2. Installing the Mounting Brackets for 23-Inch Rack Installations
Warning: Wet conditions increase the potential for receiving an electrical shock when
installing or using electrically powered equipment. To prevent electrical shock, never install or
use electrical equipment in a wet location or during a lightning storm.
Note: To insure that all optical connectors remain dust-free during installation, leave all dust
caps and dust protectors in place until directed to remove them for connection.

then secure the mounting brackets to the rack using the four machine screws provided (use
#12-24 or M6 x 10 screws, whichever is appropriate) as shown in Figure 3-3.
Figure 3-3. HU Rack Mount Installation
4 CHASSIS GROUND CONNECTION
A stud is provided on the rear side of the chassis for connecting a grounding wire to the chassis.
Use the following procedure to connect the grounding wire to the chassis and to route the
grounding wire to an approved earth ground source.
1. Obtain a length of #18 AWG (1.00 mm) insulated stranded copper wire for use as a
chassis grounding wire.
2. Terminate one end of the wire with a ring terminal.
3. Locate the chassis ground stud at the rear of the HU as shown in Figure 3-4.
4. Attach the ring end of the wire to the chassis ground stud (see Figure 3-4).
5. Route the free end of the chassis grounding wire to an approved (per local code or
practice) earth ground source.
6. Cut the chassis grounding wire to length and connect it to the approved ground source as
required by local code or practice.
Note: Provide a minimum of 3 inches (76 mm) of clearance space on both the left and
right sides of the HU for air intake and exhaust.
Note: Be sure to maintain reliable grounding. Pay particular attention to ground source
connections.

5 COAXIAL CABLE CONNECTIONS
The RF interface between the HU and the EBTS is supported through two N-type female
connectors mounted on the HU rear panel. One connector provides the coaxial cable connection
for the forward path (downlink) signal and the other connector provides the coaxial cable
connection for the reverse path (uplink) signal.
In most installations, it is usually necessary to insert some attenuation in the forward path link
between the HU and the EBTS. A signal level that is greater than –20 dBm will overdrive and
possibly damage the HU receiver. Refer to Section 4, Subsection 2.3, before completing the
forward path connection at the EBTS. If the Primary Interface Panel and Expansion Panel are
required, refer to the Digivance Long Range Coverage Solution SMR Interface Panels User
Manual (ADCP-75-143) for the installation procedures. The HU should be mounted as close as
possible to the EBTS to minimize cable losses. Use the following procedure to route and
connect the forward and reverse path coaxial cables to the HU:
1. Obtain the required lengths of high performance, flexible, low loss 50-ohm coaxial
communications cable (RG-400 or equivalent) for all coaxial connections.
2. Route the forward and reverse path coaxial cables between the HU and the EBTS interface
(per system design plan) and cut to the required length. Allow sufficient slack for dressing
and organizing cables at the HU and for installing an external attenuator in the forward
path link.
3. Terminate each cable with an N-type male connector following the connector supplier’s
recommendations.
4. Connect the forward path cable to the FORWARD RF IN connector on the HU front
panel as shown in Figure 3-5.
5. Connect the reverse path cable to the REVERSE RF OUT connector on the HU front
panel (see Figure 3-5).
Note: Do not connect the forward path cable at the EBTS until the composite forward path
RF signal level is measured and the amount of attenuation required is determined.

6. Dress and secure cables at the HU.
7. Complete all remaining coaxial connections as specified in the system design plan.
6 WDM MOUNTING PROCEDURE (OPTIONAL ACCESSORY)
A bi-directional wavelength division multiplexer (WDM) module is available as an accessory
item for the Digivance system. If the application does not require the use of a WDM system,
skip this section and proceed to Section 7.
The WDM mounts in a slot that is provided at the rear side of the HU. Use the following
procedure to install the WDM:
1. Remove the cover plate from the WDM mounting slot located on the rear side of the HU
as shown in Figure 3-6.
2. Slide the WDM into the mounting slot.
3. Push inward on the two Push/Pull fasteners to secure the WDM to the HU.
4. Carefully coil up the two WDM pigtails to protect them from damage prior to connection
to the HU optical ports.

7 OPTICAL CONNECTIONS
The optical interface between the HU and the RU is supported by two optical ports. Each optical
port consists of an SC optical adapter which is mounted on the HU rear panel. Port 1 provides
the optical fiber connection for the forward path (downlink) signal. Port 2 provides the optical
fiber connection for the reverse path (uplink) signal.
The optical connections are dependent on whether or not a WDM host module (accessory) or
CWDM host module (accessory) is installed. If the installation does not include either a WDM or
CWDM module, proceed to Section 7.1 for the optical connections procedure. If the installation
includes a WDM module, proceed to Section 7.2 for the optical connections procedure. If the
installation includes a CWDM module, refer to the Digivance System Coarse Wavelength
Division Multiplexer User Manual (ADCP-75-142) for the optical connection procedure.
7.1 Optical Connections Without WDM or CWDM system
Use the following procedure to connect the optical fibers when a WDM or CWDM host module is
not installed with the HU:
1. Obtain two patch cords that are of sufficient length to reach from the HU to the fiber
distribution panel.
Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation
can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not
look directly into the optical transmitter of any unit or exposure to laser radiation may result.
An optical power meter should be used to verify active fibers. A protective cap or hood MUST
be immediately placed over any radiating transmitter or optical fiber connector to avoid the
potential of dangerous amounts of radiation exposure. This practice also prevents dirt particles
from entering the connector.

2. Designate one of the patch cords as the forward path link and the other as the reverse
path link and attach an identification label or tag next to each connector.
3. Remove the dust caps from the HU optical ports and from the patch cord connectors that
will be connected to the HU.
4. Clean each patch cord connector (follow patch cord supplier’s recommendations).
5. Insert the connector into the appropriate optical port as shown in Figure 3-7.
Figure 3-7. Fiber Optic Cable Connections To Host Unit
6. Route the patch cords from the HU to the fiber distribution panel.
7. At the fiber distribution panel, identify the OSP optical fiber terminations that correspond
to the forward and reverse path.
8. Remove the dust caps from the from the patch cord connectors.
9. Clean each patch cord connector (follow patch cord supplier’s recommendations) and then
mate the connector with the appropriate OSP optical fiber termination.
10. Store any excess patch cord slack at the fiber distribution panel.
Note: To protect the optical receivers, insert a 10 dB attenuator in each optical path. After
the optical power has been measured, the attenuator may be resized or removed.
Note: The HU optical adapters are angled to the left. Therefore, patch cords should always
be routed to the HU from the left side of the rack. Routing patch cords to the HU from the
right side of the rack may exceed the bend radius limitations for the optical fiber.

4. Insert the connector into the WDM module’s optical port (port 1).
5. Route the patch cord from the WDM to the fiber distribution panel.
6. Identify the OSP cable optical fiber termination that corresponds to the RU.
7. Remove the dust cap from the OSP cable optical adapter and from the patch cord
connector.
8. Clean the patch cord connector (follow connector supplier’s recommendations) and then
mate the connector with the appropriate OSP cable adapter.
9. Store any excess patch cord slack at the fiber distribution panel.
10. Remove the dust caps from the PORT 1 and PORT 2 optical ports on the HU and from the
WDM pigtails that will be connected to the HU.
11. Clean each pigtail connector (follow connector supplier’s recommendations) and then
insert the connector into the appropriate optical port on the HU as shown in Figure 3-8.

8 CONTROLLER AREA NETWORK CONNECTIONS
Controller Area Network (CAN) interface connections between multiple HU’s are supported by
a pair of RJ-45 jacks. One of the jacks is designated as the NET IN port and the other jack is
designated as the NET OUT port. The CAN interface allows up to 24 HU’s to be connected
together (in daisy-chain fashion) and controlled through a single Digivance EMS computer. A
one meter long cable is available (accessory) for CAN connections. Use the following
procedure to connect CAN interface cables between multiple HU’s:
1. Connect one end of the CAN interface cable (accessory) to either the NET IN or NET
OUT port on HU #1 as shown in Figure 3-9.
Figure 3-9. Controller Area Network Connections
2. Route the CAN interface cable to HU #2 and connect the cable’s free end to the port that is
the logical opposite of the CAN interface connection at HU #1.
3. If a third HU will be connected to the network, connect a second CAN interface cable to
the remaining network port on HU #2.
4. Route the second CAN interface cable to HU #3 and connect the cable’s free end to the
port that is the logical opposite of the CAN interface connection at HU #2.
5. Repeat steps 3 and 4 for each additional HU that is added to the network up to a total of 24
HU’s. A diagram of typical CAN interface connections is shown in Figure 3-10.
Note: Always connect OUT to IN and IN to OUT. If connected to the NET OUT port at
HU #1, connect to the NET IN port at HU #2. If connected to the NET IN port at HU #1,
connect to the NET OUT port at HU #2.
