4.4 ROU (Remote Optic Unit)
ROU receives TX optical signals from ODU or OEU and converts them into RF signals. The
converted RF signals are amplified through High Power Amp in a corresponding RDU,
combined with Multiplexer module and then radiated to the antenna port.
When receiving RX signals through the antenna port, this unit filters out-of-band signals in a
corresponding RDU and sends the results to Remote Optic Module to make electronic-optical
conversion of them. After converted, the signals are sent to a upper device of ODU or OEU.
ROU can be equipped with up to three RDUs (Remote Drive Unit) and the module is composed
of maximal Dual Band.

At the rear of BIU, input and output ports are seen for each MDBU. The name of all the ports
are silk printed as "#1, #2, #3 and #4." Referring to the table above, you need to feed right
signals to input and output ports of corresponding MDBU.
Confidential & Proprietary 68/139
For each port, TX signals and RX signals are separated from each other. You don't have to
terminate unused ports unless you want to.
BIU interface with Base station Transceiver
Basically, BIU has different TX and RX ports, and so, you have only to connect input
and output ports.
Through spectrum, you need to check signals sent from BTS TX. If the signals exceed
input range (-20dBm~+10dBm), you can connect an attenuator ahead of the input port
to put the signals in the input range.
BIU interface with Bi-Directional Amplifier
Basically, BIU is in Simplexer type; when you use BDA, you need to separate BDA
signals from TX and RX type.
Using a duplexer or a circulator, you can separate TX/RX signals of an external device
Confidential & Proprietary 69/139
from each other.
Figure 5.2 – 800PS BDA Interface using Circulator
Figure 5.3 – 800PS BDA Interface using Duplexer
BIU interfaces with BDA in either of the methods above. In this case, you need to
check TX input range as well.
Confidential & Proprietary 70/139
Given the TX input range (-20dBm~+10dBm/Total per port), make sure to see if the
value is in the input range, using Spectrum Analyzer, when you connect input ports.
5.1.4 MDBU insertion
MDBU is designed to let a MDBU be inserted into any slot.
BIU can be equipped with a total of four MDBUs. If only one MDBU is inserted into a
slot with the other slots reserved, you need to insert BLANK cards into the other slots.
Confidential & Proprietary 71/139
If you do not terminate input and output ports of MCDU, which combines TX signals and
divides RX signals, it will cause loss and generation of spurious signals at the other party's band.
Given this, make sure to insert MDBU BLANK into slots of MDBU.
When MDBU is inserted into BIU, LED at the front panel will show the following information:
Confidential & Proprietary 72/139
MONITOR SMA port seen at the front panel of MDBU enables you to check current
level of TX input and RX output signals in current service without affecting main signals.
TX MON is -20dB compared with TX Input power and RX MON is -20dB as well
compared with RX Output power.
5.1.5 ODU Interface
BIU supports up to four ODUs. At the rear of BIU, eight RF input and output ports for
ODU and four power ports for power supply and communication are provided. At BIU,
you can check installation information of ODU.

ODU 1 #1 ODU-1
ODU 2 #2 ODU-2
ODU 3 #3 ODU-3
ODU 4 #4 ODU-4
Confidential & Proprietary 74/139
If ODU is not connected in the right order, related devices may fail to communicate with
each other or the unit may read wrong information. Given this, you need to connect the unit with
accurate RF Port and Signal Port in a corresponding number.
Confidential & Proprietary 75/139
For unused RF Ports for ODU expansion, make sure to terminate them using SMA Term.
Confidential & Proprietary 76/139
When you put ODU on the top of BIU, it is recommended to install the unit at least 1U
apart from BIU. Heat from BIU climbes up to reach ODU.
