2.2 Alliance 2W
L2ROU 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 L2RDU,
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 L2RDU 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.
L2ROU can be equipped with up to three L2RDUs (Remote Drive Unit) and the module is
composed of maximal Dual Band.

3.1.3 Optical Cabling
L2ROU makes optical-electronic conversion of TX signals from upper ODU and OEU and makes
electronic- optical conversion of RX signals. L2ROU 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. L2ROU 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 20/27
Optical cables should be inserted into Optic Port outside of L2ROU. Using an optical slack devices
in L2ROU, 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).
3.1.4 GND Terminal Connection
L2ROU has one GND terminal port where is on bottom side, like below
- Take off the GND terminal port from enclosure and connect to ground cable, then fix it

- The opposite end of the ground cable should connect to the communication GND of
building
3.1.5 Coaxial cable and Antenna Connection
- The coaxial cables which are connected to antenna distribued network connect to
antenna port of L2ROU. Before connection, check the VSWR value of coaxial cable
whether it is within specification using SITEMASTER .
- At this time, check if the Return loss have above 15dB or VSWR have below 1.5
- The part of antenna connection fasten to port not to be loosed and not to be injected the
dusty and insects
- The antenna connected to L2ROU is only serviced in inbuilding
3.1.6 Insertion of L2RDU
L2ROU has slots to enable up to three L2RDU modules to be inserted into the unit.
You can insert a L2RDU into any slot. It is not possible to provide services with a L2RDU module
