Clear The Laser-Off-Wvl-Drift Condition - Cisco NCS 2000 series Troubleshooting Manual

Alarm Troubleshooting
The Laser shutdown due to wavelength drift condition is raised when the transmit wavelength of the
ONS-XC-10G-C XFP drifts beyond the threshold limit. This causes the TX laser to shut down to avoid
transmitting a wavelength that is not provisioned in the network.

Clear the LASER-OFF-WVL-DRIFT Condition

SUMMARY STEPS
1. Provision a different wavelength or replace the affected ONS-XC-10G-C XFP. Refer to the NTP-G326
Install, Provision, and Delete PPMs section in the
Modules in Cisco ONS Platforms
DETAILED STEPS
Provision a different wavelength or replace the affected ONS-XC-10G-C XFP. Refer to the NTP-G326 Install, Provision,
and Delete PPMs section in the
replace the affected XFP.
If the condition does not clear, log into the Technical Support Website at
for more information or call Cisco TAC (1 800 553-2447).

The Laser Bias Current Degrade alarm occurs on an amplifier card (OPT-BST, OPT-PRE, OPT-AMP-C, or
OPT-AMP-17-C), 40-SMR1-C, and 40-SMR2-C cards when laser aging causes a degrade, but not failure, of
laser transmission.

Warning Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector. Do
not stare into the beam directly with optical instruments. Viewing the laser output with certain optical
instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm could
pose an eye hazard. Statement 1056
