MIL-PRF-28876 Connectors

As an industry standard fiber optic interconnect for shipboard and ship-to-shore uses, the Timbercon MIL-PRF-28876 has become the universal standard connector for Navy applications. The MIL-PRF-28876 is constructed out of aluminum alloy with double start threads for extra durability in rough environments. This connector meets the U.S. Navy’s stringent MIL-S-901 Grade A Medium shock requirement.

The MIL-PRF-28876 is available in plug, wall-mount receptacles, and jam-nut mounted receptacles in a full range of standard insert arrangements. This connector uses the MIL-T-29504 /14 and /15 sealed termini which Timbercon terminates in our factory using custom, automatic polishing fixtures.

Timbercon utilizes high-reliability fiber optic connectors, such as the MIL-PRF-28876, to produce precision alignment of optical fibers. Connectors with polarization keys and keyways are manufactured to exacting tolerances to reduce radial misalignment and insertion loss. Timbercon military specific connectors also incorporate a bottoming surface to ensure reliable shell-to-shell connection. This attribute ensures that the linear dimensional relationship of the contact termini are the same. Contact Timbercon to learn more about MIL-PRF-28876 fiber optics.
