.
C:
Optical output connectors dirty.
S:
Disable optical output and clean optical connectors.
C:
Use of incorrect optical adapters or connectors.
S:
Use only the indicated optical adapters and connectors. If
measurement instruments accept different connector type, then
use hybrid patchcords. For shorter wavelengths (<1300nm), use
of special coupling patchcords with matching wavelength will be
necessary to couple the light efficiently.
C:
Optical output connector damaged.
S:
Measure optical output power with power meter and compare
with readout on Main Display. Return to Optilab for repair if the
difference is high (>4 dB) and cannot be corrected by cleaning or
replacing the optical connectors. Always apply dust cover plugs
to unused optical receptacles to prevent the damage of internal
optical connectors.

C:
Insufficient optical output isolation.
S:
Connect isolator of corresponding wavelength to optical output
connector. The use of angled patchcords (APC) will help minimize
the light being reflected back into the laser and improve stability.
