M28876 Fiber Optic Connectors

Amphenol Fiber Systems International M28876 Fiber Optic Connectors are precision-machined to stringent tolerances and designed to provide superior optical performance in extreme environmental conditions. These circular fiber optic connectors are designed and qualified to MIL-PRF-28876, Rev E. The series offers rugged military and industrial multi-channel fiber optic connectors for deployable, shipboard, outdoor, and fixed-system requirements. The backshell features the Quickloc™ captivation system that Amphenol Fiber Systems International developed and offers easy installation. It is also easy to remove the aramid yarn of the cable (KEVLAR®) captivation and recapture without cutting back the cable. The Quickloc backshell allows easy access to maintain or reconfigure termini without altering the captivated aramid fiber.
