Amphenol Fiber Systems International TFOCA-II® 4-Channel Fiber Optic Plug Assemblies

Amphenol Fiber Systems International (AFSI) TFOCA-II® 4-Channel Fiber Optic Plug Assemblies are deployable connectors featuring the TFOCA-II sealed free-floating termini. The unique termini design enables TFOCA-II connectors to seal against high humidity and moisture conditions while allowing the mated termini's full axial and orbital movement, providing low insertion loss and minimal back reflection. The hermaphroditic AFSI TFOCA-II® 4-Channel Fiber Optic Plug Assemblies are designed and patented for deployable network applications in environmentally harsh conditions.

Features

Versatile hermaphroditic, physical contact design enables multiple TFOCA-II® plug assemblies to be concatenated
Removable end cap allows for easy field maintenance and cleaning
4-channel connector design offers a two-fold improvement over TFOCA with better optical performance
Improved cable retention strength, designed to meet 400lb pull strength while protecting fibers from stress
ZnNi-plating provides substantial longevity to corrosive environments and meets the mandate set by the Environmental Protection Agency for eliminating heavy metal plating
Commercial ceramic ferrule technology enables the TFOCA-II® connectors to provision multimode and single-mode interconnects with a variety of polishes, including SPC and UPC
Solid core alignment sleeves are more robust than split alignment sleeves
Hermaphroditic dust cap, plug, and/or receptacle dust caps connect together to prevent dust and moisture penetration during deployable conditions
Optional key positions (four key positions: 1, 2, 3, and universal) available that enable segregation of mated plug/receptacles or plug/plug through a mechanical interface
Field repairable using existing parts, additional connector components (other than termini) are not required to perform field repair
Also available in stainless steel and brass, allowing the connector to be used in a variety of applications
