0x8001 The internal temperature
exceeds the high alarm lim‐
it. The transceiver is too hot.
0x8002 The TX Bias voltage exceeds
the high alarm limit. The
transmit diode current is
too high.
0x8003 The TX Bias voltage drops
below the low alarm limit.
The transmit diode current
is too low.
0x8004 The optical TX power ex‐
ceeds the high alarm limit.
The sent optical power is
too high.
0x8005 The optical TX power drops
below the low alarm limit.
The sent optical power is
too low.
0x8006 The optical RX power ex‐
ceeds the high alarm limit.
The received optical power
is too high.
Remedy
1. Check to ensure that the alarm limit is set to
the correct value.
2. Check whether the ambient temperature of
the IM is within the specified temperature
range.
3. Replace the SFP transceiver.
4. Contact Technical Support.
1. Check to ensure that the alarm limit is set to
the correct value.
2. Replace the SFP transceiver.
3. Contact Technical Support.
1. Check to ensure that the alarm limit is set to
the correct value.
2. Check the remote SFP transceiver (same
wavelength, optical transmit power).
3. Replace the SFP transceiver.
4. Contact Technical Support.
