Description
EDFA A-B output power alarm. If the
output power is within 1.5 dB of the
threshold for the minimum output power,
an alarm is triggered.
A-B is the A to B direction (for example,
east to west).
EDFA A-B calibration table error.
EDFA B-A case temperature alarm. When
the EDFA case temperature is above
80° C, this alarm is triggered.
B-A is the B to A direction (for example,
west to east).
EDFA B-A module reflection alarm. This
alarm is triggered when there is high back
reflection at the output port of the
optical ILA.
B-A is the B to A direction (for example,
west to east)
EDFA B-A is out of gain. This alarm is
triggered if the difference between the
gain setting and the actual achieved gain
is more than 0.5 dB.
B-A is the B to A direction (for example,
west to east).
EDFA B-A pump 0 has reached its end
of life.
B-A is the B to A direction (for example,
west to east).
EDFA B-Apump 1 has reached its end of
life.
B-A is the B to A direction (for example,
west to east).
EDFA B-A pump 0 temperature alarm. If
the pump temperature is below 20° C or
greater than 30° C, an alarm is triggered.
B-A is the B to A direction (for example,
west to east).
Chapter 12: Operational Commands
Corrective Action
When the output power is at least 1.5 dB
greater than the threshold value, the
alarm is cleared.
Return the device by using an RMA.
When the EDFA case temperature is
below 80° C, the alarm is cleared.
Check that the fiber-optic cable is
connected at the output port, and if it is
connected, clean the fiber-optic cable
and reconnect it.
Wait for the optical ILA control loops to
self--adjust.
Reset the optical ILA, or return the device
by using an RMA.
Reset the optical ILA, or return the device
by using an RMA.
When pump temperature is between 20°
and 30° C, the alarm is cleared.
