System Configuration and Functions
2.1 ROU (Remote Optic Unit)
ROU consist of two unit which one is MRU(Main Remote Unit) and the other is ARU(Add on Remote
Unit). We simply called as ROU combination of MRU and ARU
MRU 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 RU, combined with Multiplexer
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 RU 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.
MRU and ARU are composed of maximal dual band
The most difference of MRU an ARU is whether existence of optical module is in it or not

3.1.3 Optical Cabling
MRU makes optical-electronic conversion of TX signals from upper ODU and OEU and makes
electronic- optical conversion of RX signals. MRU has one optical module in it. As WDM is installed in
the R_OPT module, two pieces of wavelength (TX:1310nm, RX:1550nm) can be sent/received with
one optical strand at the same time. MRU 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 are recommended to clear them using alcohocol to remove dirt.
