Project Description

TFOCA Multi-Channel Fiber Optic Connectors

Physical Contact Connectors – Hermaphroditic Connectors

In 1999, Amphenol Fiber Systems International (AFSI) designed the TFOCA connector series as a direct replacement for the connector portion of the US Army’s legacy TFOCA (Tactical Fiber Optic Cable Assembly) equipment. This connector series has become known simply as “TFOCA.” The AFSI TFOCA series has been formally approved by CECOM (US Army Communications Electronics Command Fort Monmouth, New Jersey) and meets the performance criteria as specified in MIL-C-83526. In addition, AFSI is fully qualified and formally approved by CECOM to fabricate cable assemblies using the AFSI TFOCA connector. These assemblies have been tested in accordance with MIL-C-49292.

The TFOCA connector is a hermaphroditic design utilized for tactical deployable communications systems. This genderless characteristic allows for concatenations of cable assemblies without regard for connector interface compatibility.

The ruggedized connector and housing will withstand the repeated handling and mating cycles typically required for rapid fiber optic cable deployment and retrieval in a tactical environment.


The TFOCA’s unique design and environmentally protected construction provide protection from high compressive and tensile loads. Seals at every interface ensure outstanding resistance to moisture penetration. The cable termination is designed to firmly anchor the cable Kevlar® strength members to the connector housing without special tooling. The AFSI TFOCA connectors can be terminated and repaired in the field using existing US Army equipment or the AFSI TFOCA Termination Kit (P/N KTBK7000).
