TFOCA-III® Fiber Optic Connectors

Physical Contact Connectors – Hermaphroditic Connectors

The TFOCA-III® series of 6 & 24-channel fiber optic connectors are ideal for environmentally harsh conditions.

The TFOCA-III® design utilizes the latest technology in fiber optic connectivity by incorporating industry standard physical contact ceramic ferrules and alignment sleeves.


  • Hermaphroditic design for versatility – enables multiple TFOCA-III® plug assemblies to be daisy-chained
  • Removable end cap allows for easy field maintenance and cleaning
  • 6 & 24-channel connector design is ideal for high-density harsh environment applications
  • Superior cable retention strength is designed to meet 400 lb pull strength while protecting fibers from stress
  • Zn-Ni plating provides substantial longevity to corrosive environments. Meets new mandate set by the Environmental Protection Agency for elimination of heavy metal plating
  • Commercial ceramic ferrule technology enables TFOCA-III® connector to provision multimode and single mode interconnect 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, 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, which allows the connector to be used in a variety of applications


  • US Army, Navy, and Marine Corps military tactical deployments
  • Oil, gas and geoscience industries
  • Mining
  • Industrial
  • Broadcast
  • Disaster recovery
