The Molex SC/APC connector combines a Telcordia and IEC tested connector design with a uniquely precise, pre-angled,
pre-radiused, and pre-polished Angled Physical Contact (APC) ferrule. The result is an APC connector with superior insertion
and return loss performance.
Ferrule endface geometry is especially critical in angled fiber optic connectors. For this reason, Molex has developed a
unique polishing process which in addition to putting an 8 degree angle on the ferrules, also provides a 10mm radius. With
this endface geometry, physical contact of the fibers is maintained, ensuring a minimum insertion loss and a maximum return
loss. Combining this pre-polished ferrule with the preassembled 1-piece body design has produced a superior performance
APC connector that is easy to terminate both in the factory and in the field.
A shield against exposure to laser radiation and a barrier to dust contamination are 2 features of a series of shuttered SC
adapters. These adapters are equipped with a spring loaded shutter which automatically closes when a connector is
removed from the adapter. Both the shuttered and the standard SC adapter styles are available with either zirconia ceramic or
phosphor bronze alignment sleeves.
