MIL-ST Fiber Optic Connectors
For Military & Commercial Use
MIL-ST Connectors
About Mil-ST Connectors
Amphenol Fiber Systems International (AFSI) offers
rugged military fiber optic ST connectors for deployable
and fixed communication systems. These connectors meet
the stringent requirements of MIL-C-83522. AFSI’s
connectors are designed to provide the best possible optical
performance in applications with severe environmental
conditions.
The M83522 connector features a higher spring force than
commercial ST connectors, allowing it to meet the shock
and vibration requirements of MIL-C-83522. Stainless steel
construction provides excellent mechanical strength and
superior corrosion resistance. The boot is attached either
by compression ring or by a threaded adapter.
US Navy approved Commercial-off-the-Shelf (COTS) ST
connectors provide the same robustness with a spring force
more consistent with commercial ST connectors. The
COTS product is designed for use in shock-isolated
environments, or to interface with commercial electronics
and non-mil-spec ST adapters. It is also appropriate for
applications where corrosion resistance and mechanical
strength are desirable.
