Project Description


Fiber Optic Connectors

Amphenol Fiber Systems International (AFSI) manufactures a complete line of next generation circular fiber optic connectors designed to meet the needs of harsh environment applications. Building on the legacy of MIL-PRF-28876, Rev. E these connectors incorporate the latest technologies in fiber optic interconnect design. These connectors are precision machined to stringent tolerances and designed to provide superior optical performance in extreme environmental conditions.

The backshells feature the Quickloc™ captivation system developed by Amphenol Fiber Systems International. Not only is it simple to install, it is also easy to remove the captivated aramid yarn of the cable and recapture without cutting back the cable. The Quickloc™ backshell also allows easy access to maintain or reconfigure termini without altering the captivated aramid fiber.
