About the TFOCA-II®Connector
In 1999, Amphenol Fiber Systems International, in conjunction
with the United States Army Communications-Electronics
Command (CECOM), designed the “next generation” deployable
fiber optic connector for the emerging “knowledge-centric
warfare communication” requirements of the future battlefield.
By combining the effective technology of both Amphenol Fiber
Systems International’s FS3H hermaphroditic and AT&T’s
TFOCA deployable fiber optic connector, the family of
TFOCA-II®connectors was born, becoming an enabling
technology for the digital battlefield.
The heart of the TFOCA-II®family of deployable fiber optic
connectors centers on 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 full axial and orbital movement of the mated
termini, providing low insertion loss and minimal back reflection.
This unique connector series was designed and patented by
Amphenol Fiber Systems International for use in
environmentally harsh conditions. The U.S. Army has
standardized on the 4-channel TFOCA-II®connector as the next
generation fiber optic connector for military tactical deployable
network applications.
Features and Benefits
•Hermaphroditic Design for Versatility - Enables multiple
TFOCA-II®plug assemblies to be concatenated.
•Removable End Cap - Allows for easy field maintenance
and cleaning.
•4-Channel Connector Design - Two fold improvement
over TFOCA with better optical performance.
•Improved Cable Retention Strength - Designed to meet
400lb. pull strength while protecting fibers from stress.
•Zn-Ni Plating - Provides substantial longevity to corrosive
environments. Meets new mandate set by Environmental
Protection Agency for elimination of heavy metal plating.
•Commercial Ceramic Ferrule Technology - Enables
TFOCA-II®connector to provision multimode and
single mode interconnect with a variety of polishes including
SPC and UPC.
•Solid Core Alignment Sleeves - 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, universal) available, enabling segregation of mated
plug/receptacles or plug/plug, through 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 - Allows the
connector to be used in a variety of applications.
Applications
• U.S. Army, Navy, and Marine Corp military tactical
deployments
• Oil, Gas and Geoscience industries
• Industrial
• Broadcast
