These modules comply with the
Class 1 Eye Safety standards as DataShee
outlined by CDRH1040.10&11, as
well as IEC825-1 and –2.
The PD-LD BiDirectional modules
are assembled using laser welding
processes. This technique guaran-
tees a semiconductor to optical fi-
ber interface that remains stable
over mechanical and environ-
mental and environmental ex-
tremes. The optical semiconductor
die are mounted within hermeti-
cally sealed TO can subassemblies
making them impervious to con-
taminants and moisture.
WDM BiDirectional modules are
built with 1 meter long 9/125/900

These fibers may be terminated
with most standard fiber optic con-
