Fiber Optic Connectors & Contacts

A terminus is a device used to terminate, hold, and position an optical fiber within a connector, and termini refers to more than one. The MIL-T-29504 (M29504) is a military specification for termini and is qualified to MIL-PRF-29504B specifications. This series of fiber optic termini offers outstanding optical and mechanical performance and are compatible with M28876 and comparable to other military connectors.

All fiber optic connectors and contacts are offered fully terminated and tested ensuring signal integrity for ruggedized application environments.
