ROU Optic Comp Operation
ROU has the function of automatically compensating for optical loss. It can do the
5dBo of optical loss. Set “
TX OPTIC COMP
can not be made without communication with such units in upper level as ODU or OEU. For
1dBo of optical loss, basic TX OPTIC ATT is 12
4dB. OPTIC COMP works only one time before it stays dormant.
The figure below shows a screen for OPTIC Information in ROU GUI.
LD POWER means output level of ROU Laser Diode, which is sent to a upper unit by ROU. PD
POWER means
input level of Photo Diode to be received from a upper unit.
During optical compensation, the Result window shows "Processing" and then a result value.
There are three types of results as follows:
1.
Success: The optical compensation is normally made.
2. Over
Optic Loss: Generated optical loss is 5dBo or more.
3.
Communication Fail: Communication with ROU is in poor conditin.
If ROU does not make optical compensation, there will be erors in the bu
link. It can cause lower output level or make Spurious Emission not satisfying for a standard.
RDU Setting
Insert an RDU+BPF assembly you want to offer service with it and then
with interface cable (See Sector 5: How to install RDU at the INSTALL part).
Through GUI, check if the ID of RDU module is inquired at LEFT, MIDDLE and RIGHT slots of
