Fiber Optic Connectors, Cable Assemblies and Active Optics for Harsh Environments

Fiber Optic Connectors and Cable Assemblies for Harsh Environments

Cinch design and manufacture fiber optic connectors and cable assemblies for military, security, outside broadcast, offshore, mining and other industrial harsh environment applications.

Our expanded beam connectors and cable assemblies offer high performance, flexible, cost effective solutions to any critical harsh environment communication application. Our product offering includes, physical contact, rectangular and circular connectors, hybrid connectors with fiber and copper, media converters, harnesses, reels and other active and passive devices. We also manufacture custom cable assemblies from 1m to 5km+ using high quality tactical fiber optic cable and rugged field deployable cable reels.

Expanded Beam Fiber Optics & EBOSA™ Technology: The Cinch Advantage

Cinch EBOSA™ (Expanded Beam Optibal Sub-Assembly) expands and collimates the optical beam up to 2000 times the original beam size making contaniments nearly benign to beam continuity and integrity.

Our patented active alignment technology aligns a standard LC ferrule to Cinch’s EBOSA™ with ultra-high precision. This results in insertion loss and reflectance performance that meets the MIL-DTL-83526/20 & /21 specification and can exceed the specification for customer specific applications.
