4 Maintenance and Service
Protect the PDB48xC-AC from adverse weather conditions. The PDB48xC-AC is not water res-
istant.
Attention
To avoid damage to the instrument, do not expose it to spray, liquids or solvents!
The unit does not need a regular maintenance by the user. It does not contain any modules
and/or components that could be repaired by the user himself. If a malfunction occurs, please
contact Thorlabs for return instructions.
Do not remove covers!
To clean the PDB48xC-AC series housing, use a mild detergent and damp cloth. Do not soak
the unit in water or use solvent based cleaners.
Cleaning of the fiber connectors
The photodiodes of the PDB48xC-AC
are pigtailed with single mode fiber
and connectorized by FC/APC con-
nectors. Clean and dust-free surfaces
of the ferrule tips are essential to
minimize coupling losses. If the con-
nectors are suspected to be soiled,
the ferrule tips can be cleaned this
way:
Remove the two screws (1), fixing the
front part (2) of the switchable ad-
apter. Detach the front part (2) an
clean the ferrule tip using a lint-free
tissue damped with alcohol or pro-
panol. The ferrule receptacle of the
front part (2) can be cleaned from
dust using compressed air (duster).
When mounting the front adapter, take care for it's correct orientation: The cylindrical key of the
front part must match with it's counterpart in the PDB48xC-AC's housing.
Warning
The screws (3), fixing the base of the switchable adapter to the housing, must not be re-
moved !
