Probable Cause Suggested Corrective Action
OM:
RAMAN
CR The incoming
optical signal
power level of the
OSC signal has
fallen below the
minimum level
able to be
detected by the
input monitor.
1 Verify that the incoming cable is the
correct cable and that the transmit
and receive ports are connected to
their proper respective portions of
the cable (i.e. that the fibers are not
swapped between transmit and
receive).
2 Verify that the OSC facility
transmitted by the far-end is
correctly configured, that it is
operating normally, and that it is
correctly connected into the
transmission fiber.
3 Verify that the incoming fiber is
firmly connected to the receive port
associated with the facility and that
the connector is not physically
impaired by obstructions, dirt or
component damage. Clean the
connector or replace the cable, plug
or module, as appropriate,
depending upon the cause
determined from the physical
examination.
4 Verify that a signal is present at the
cable termination and that the signal
conforms to the required
specifications (e.g. minimum and
maximum power levels). If the
signal meets the required
specifications proceed to the next
step below, otherwise locate the
source of the signal problem
upstream and repair the problem.
5 Replace the module supporting the
facility.
