Description
EDFA A-B module reflection alarm. This
alarm is triggered when there is high back
reflection at the output port of the
optical ILA.
A-B is the A to B direction (for example,
east to west).
EDFA A-B 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.
A-B is the A to B direction (for example,
east to west).
EDFA A-B pump 0 has reached its end
of life.
A-B is the A to B direction (for example,
east to west).
EDFA A-B pump 1 has reached its end of
life.
A-B is the A to B direction (for example,
east to west).
EDFA A-B pump 0 temperature alarm. If
the pump temperature is below 20° C or
greater than 30° C, an alarm is triggered.
E-ab is the A to B direction (for example,
east to west)
EDFA A-B pump 1 temperature alA-B is
the A to B direction (for example, east to
west).arm. If the pump temperature is
below 20° C or greater than 30° C, an
alarm is triggered.
A-B is the A to B direction (for example,
east to west).
EDFA A-B input power alarm. If the input
power is within 1.5 dB of the threshold
for the minimum input power, an alarm
is triggered.
A-B is the A to B direction (for example,
east to west).
Corrective Action
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.
When pump temperature is between 20°
and 30° C, the alarm is cleared.
When the input power is at least 1.5 dB
greater than the threshold value, the
alarm is cleared.
