Optical Performance Distribution

The Molex FC Angled Physical Contact (APC) connector series combines a NTT-FC connector design with a uniquely precise,

pre-angled, pre-radiused and pre-polished ferrule to deliver superior APC performance. This connector is available with

either the NTT-FC standard or non-standard, tight fit key configuration.

In angled fiber optic connectors, the ferrule endface geometry is especially critical. This is the reason Molex has developed a

unique polishing process which not only polishes an 8 degree angle on the ferrule endface, but also 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 the pre-polished ferrule with the preassembled 1-piece body design produces a superior performance APC

connector that is easy to terminate in either the factory or in the field.

Flange mount or “D” hole adapters, in both standard or tight fit key configurations, provide connector-to-connector mating.
