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.

2) Remote Power Supply Unit (RPSU)
RPSU receives -48V of input. This unit is divided into DC/DC type to output +6V, +9V and +27V
of DC power and AC/DC type to receive 120V of AC input and to output +6V, +9V and +27V of
DC power.
Upon order, either of the two types should be decided. MS Connector, which uses ports to

different.
RPSU has a circuit brake to turn the power ON/OFF and has LED indicator at the top to check if
input power is normally supplied.
3) Remote Optic(R OPTIC)
Remote Optic converts optical signals into RF signals and performs vice versa. With an FSK
modem in it, the unit communicates with upper devices.
It also has internal ATT for optical compensation to compensate for optical cable loss, if any.

the front of the module, it has LED indicator to show system status, letting you check any
abnormalities at a time. At the same front, it also has communication LED Indicators to show
communication status with upper devices. Through RS-232C Serial Port, the unit enables you to
check and control device status through PC and laptop. This equipment is indoor use and all the
communication wirings are limited to inside of the building.

Multiplexer works as a module to combine or distribute multiple signals into one antenna.
This device has a port to combine multiple signals. You need to connect input and output ports
of RDU through a corresponding port.

Add on V/UHF ROU
Add on V/UHF ROU(forward naming“AOR) is connected existing ROU to service VHF and UHF
band. AOR should support VHF+UHF RDU only, not support other RDUs which have cavity
filter. RDUs which have cavity filter is too big so that AOR body can’t accommodate these.
AOR locates above or under of exisiting ROU. AOR receives TX signals from ROU and then
amplify these through High Power Amplifier, filter out of band signals and radiated to the TX
antenna port. When receiving RX signals through the RX antenna port, this unit filters out-ofband signals and amplify with Low noise Amlifier and output power is connected existing ROU’s
RX port. External BPF should be located between TX/RX antenna and AOR’s IN/OUT ports
because the BPF rejects the strong broadcasting signal and etc
AOR body meets to NEMA4 degree.

RF Interface at BIU
BIU can be connected with Bi-Directional Amplifier and Base Station Tranceiver.
To connect BIU with BDA, you need to use a duplexer or a circulator to separate TX/RX signals
from each other.
BIU can feed external TX/RX signals from the Back Plane.
Using MDBU separated from each carrier band, BIU can easily expand and interface with bands.
As seen in the table below, MDBU is divided into Single and Dual Bands. The unit can be
connected with two to four carrier signals per band. At the rear, #1~4 marks are seen in order
per MDBU. The following table shows signals to be fed to corresponding ports:

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
67/139
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
68/139
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
69/139
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
70/139
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:

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.

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.
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
