5.2 ODU Installation
ODU should be, in any case, put on the top of BIU. This unit gets required power and RF
signals from BIU. The following table shows components of ODU:

RF Cable SMA(F) to SMA(F), 400mm 2EA
Common Part
Signal Cable 2Row(15P_F) to 2Row(15P_M),650mm 1EA
Optional Part DOU Optical Module with 4 Optic Port Up to 2EA to be
inserted
5.2.1 ODU Shelf Installation
ODU is a shelf in around 1U size. Its width is 19” and so this unit should be inserted into a 19”
Standard Rack. ODU should be, in any case, put on the top of BIU. BIU should be distant
around 1U when the unit is installed.
5.2.2 ODU Power Cabling
ODU does not operate independently. The unit should get power from BIU.
When you connect 2-column, 15-pin D-SUB Signal cable from BIU and install DOU, LED on the
front panel is lit. Through this LED, you can check state values of LD and PD of DOU.
5.2.3 ODU Optic Cabling
As optical module shelf, ODU makes electronic-optical conversion of TX signals and then
makes optical-electronic conversion of RX signals. ODU can be equipped with up to two DOUs.
One DOU supports four optical ports and one optical port can be connected with ROU.
Optionally, only optical port 4 can be connected with OEU.
As WDM is installed in DOU, the unit can concurrently send and receive two pieces of
wavelength (TX:1310nm, RX:1550nm) through one optical core. DOU has SC/APC of optical
adaptor type.
Confidential & Proprietary 62/87
Figure 5.4 – Optical cable of SC/ACP Type
For optical adaptor, SC/APC type should be used. To prevent the optical access part from being
marred with dirt, it should be covered with a cap during move. When devices are connected
through optical cables, you need to clear them using alcohocol to remove dirt.
5.2.4 Insert DOU to ODU
In an ODU Shelf, up to two DOUs can be installed. DOU module is in Plug in Play type.
When you insert DOU in ODU, insert the unit into the left DOU1 slot first. You can be careful as
the number is silk printed at the left.
The following figure shows installation diagram of ODU with one DOU inserted in it.
The following figure shows installation diagram of ODU with two DOUs inserted in it.
When you insert DOU into ODU, insert the unit into the left DOU1 slot first. Into unused
slot, you need to insert BLANK UNIT in any case.

5.2.5 Consumption Power of ODU
ODU gets power from BIU. One ODU can be equipped with up to two DOUs. Depending on
how many DOUs are installed, power consumption varies. The table below shows power
consumption of ODU:
Part Unit Consumption Power Remark
ODU_4 DOU 1 EA 13W
ODU_8 DOU 2 EA 26W
5.3 ROU Installation
5.3.1 ROU Enclosure installation
ROU is designed to be water- and dirt-proof. The unit has the structure of One-Body enclosure.
It satisfies water-proof and quake-proof standards equivalent of NEMA4.
ROU can be mounted into either of a 19” Standard Rack or on a Wall.
Basically, ROU has both of a Wall Mount Bracket and a Rack Mount Bracket.
Depending on the use of the Rack Mount Bracket, the bracket can be removed.
The following shows dimension of the fixing point for the Wall Mount Bracket.

Figure 5.6 – Dimension used to install ROU on the WALL
ROU Wall Mount Installation
Turn M12 Fixing Screws by half on the wall and fully fix the screw with a Wall Mount Bracket on
it.
For convenience, the Wall Mount Bracket has fixing holes to let you easily mount an enclosure.
Turn the M5 Wrench Bolt by half at each side of the Heatsink of the enclosure.
Confidential & Proprietary 65/87
Put the enclosure with the M5 Wrench Bolt fixed on the fixing groove and fix the M5 Wrench
Bolts into the remaining fixing holes.
In this case, you will use 12 M5 Wrench Bolts in total except bolts used for the fixing groove.
ROU Rack Mount Installation
Like other units, ROU is designed to be inserted into a rack. The unit occupies around 13U of
space except cable connection.

Basically, the common part of ROU should have an enclosure and it is equipped with RCPU to
inquire and control state of each module, R_OPTIC to make both of electronic-optical and
optical-electronic conversions, RPSU to supply power for ROU and a Multi-Plexer to help share
multiple TX/RX signals through one antenna. It should have Power Cable for external rectifier or
to supply required power.
Confidential & Proprietary 67/87
In addition, RDU can be inserted and removed to provide service for desired band (Optional).
5.3.2 ROU Power Cabling
ROU supports both of DC-48V and AC120V of input power. As RPSU for DC-48 and RPSU for
AC120V are separated from each other, you need to select one of them in case of purchase
order.
RPSU for DC -48V and RSPU for AC 120V have the same configuration and capacity while
each of the units uses different input voltage from each other.
The following figure shows configuration of RPSUs for DC -48V and AC 120V.

Check if the connection is the same as one seen in the table above and make sure to turn the
power ON.
5.3.3 Optical Cabling
ROU makes optical-electronic conversion of TX signals from upper ODU and OEU and makes
electronic- optical conversion of RX signals. ROU has one optical module in it. As WDM is
installed in the R_OPTIC module, two pieces of wavelength (TX:1310nm, RX:1550nm) can be
sent/received with one optical core at the same time. ROU has SC/APC of optical adaptor type.
For optical adaptor, SC/APC type can be used. To prevent the optical access part from being
marred with dirt, it should be covered with a cap during move. When devices are connected
through optical cables, you need to clear them using alcohocol to remove dirt.
Confidential & Proprietary 69/87
Optical cables should be inserted into Optic Port outside of ROU. Using an optical slack devices
in ROU, you need to coil around one or two roll of cables to be connected with the optical
adaptor of ROPTIC.
At this time, curvature of the optical cable should be at least 10Ø to prevent insertion loss from
being increased.
Through GUI, check if PD value of ROPTIC is in a tolerable range (+4~-1dBm).
5.3.4 Insertion of RDU
ROU has slots to enable up to three RDU modules to be inserted into the unit.
You can insert a RDU into any slot. It is not possible to provide services with a RDU
module alone; you need to connect the module with Cavity BPF in any case.
The table below shows types of RDU and CAVITY BPF:

into ROU at the same time. In the same way, you cannot concurrently insert both of 850C RDU
and 850C+700PS RDU into ROU.
Information of LED at the front RDU
RDU has the structure of enabling a random RDU to be inserted into three slots.
ROU can be equipped with a total of three RDUs. If only one RDU is inserted into a slot
and the other slots ramian reserved, you need to insert BLANK cards into the other
slots.
When RDU is inserted into ROU, LED of the front panel shows the following
information:

For power consumption of ROU, the common part consumes 17W. Depending on the
quantity of each RDU, you can add overall power consumption of ROU. Only, in case
of Dual-Band signals, power consumption is calculated respectively when HPA of the
other party is turned OFF and two HPA devices are turned ON. Note that when you
calculate Power Budget.
5.4 OEU Installation
OEU is used to expand ROU in Campus Site.
OEU is located at a Remote Closet. As it can be equipped with up to two DOUs
, you can expand a total of eight ROUs.
5.4.1 OEU Shelf installation
OEU is a shelf in around 2U size. Its width is 19” and so this unit should be inserted into a 19”
Standard Rack. OEU is in a Remote Closet, providing optical ports of ROU.

seen at the rear of OEU.
Terminal Color of cable Description Remark
-48V Blue color Input range: -42 ~ -56Vdc
NC Not Connected
GND Black color
Before connecting the power terminal, you need to connect "+" terminal of Multi Voltage Meter
probe with the GND terminal and then connect "–" terminal with -48V to see if “-48Vdc” voltage
is measured. After the check, connect the power terminal through the terminal seen below.
Note that OEU does not operate if the "+" terminal and the "–" terminal of the -48V power
are not inserted into the accurate polarity.
5.4.3 OEU Optic Cabling
OEU is connected with upper ODU. With DOU inserted in it, the unit is connected with ROU.
Confidential & Proprietary 79/87
As OEU has a shelf with EWDM in it, the unit makes electronic-optical conversion of TX signals
from ODU and makes optical-electronic conversion of RX signals. In addition, OEU can be

9. Using spectrum analyzer, measure the input range from BTS/BDA if the range is
between -20dBm and +10dBm.
10. If the level exceeds the range, need to connect an attenuator with the front end of BIU
input to adjust the level in the corresponding range.
11. turn the power on for all units and make sure all the alarms in normal status by GUI
monitoring.
