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).
