Amphenol Fiber Systems International TFOCA-II Fiber Optic Connectors & Termini
Amphenol Fiber Systems International TFOCA-II Fiber Optic Connectors and Termini are AFSI designed to provide reliable function in harsh battlefield conditions for military applications. The robust, free-floating termini allows the TFOCA-II connectors to seal tightly against high humidity and moisture. The mated connector and termini enable full axial and orbital movement while providing low insertion loss and back reflection. The TFOCA-II family features a four-channel connector design, which is a two-fold channel increase over the TFOCA line, and better optical performance. The connectors offer an improved cable retention strength of 400lbs and protect fibers from stress. The Amphenol Fiber Systems International TFOCA-II Fiber Optic Connectors have commercial ceramic ferrule technology enabling multimode and single-mode interconnect with SPC and UPC polishes.
The TFOCA-II MTFP Termini are built in accordance with MIL-PRF-29504/16 and feature a double-floating seal design. The design allows maximum terminus travel with minimum side forces and ensures maximum optical isolation and terminus sealing. The TFOCA-II connectors and MFTP termini are ideal for military, oil, gas, geoscience, mining, and industrial applications.
