Project Description

TFOCA-II® 12-Channel RigLinQ

Hybrid Fiber Optic Connectors

The TFOCA-II® 12-channel RigLinQ fiber optic connector is ideally suited for environmentally harsh conditions. Hybrid design lowers overall systems cost and greatly reduces panel mount foot print by combining optical and electrical signals in one quick connect housing. The unique TFOCA-II®connector series is designed and patented by Amphenol Fiber Systems International.

This design takes advantage of the latest in fiber optic connectivity technology by utilizing an industry exclusive fully articulating optical termini for superior optical performance and environmental open-face sealing.

The TFOCA-II® RigLinQ connector is designed for minimal maintenance in the field. Field cleaning if required is facilatated by a removable end cap allowing direct access to the alignment sleeves and termini.

Features & Benefits

  • Hermaphroditic Design for Versatility – Enables multiple TFOCA-II® plug assemblies to be concatenated
  • Removable End Cap – Allows for easy field maintenance and cleaning
  • Improved Cable Retention Strength – Designed to meet 400 lbs pull strength while protecting fibers from stress
  • Ni-PTFE Plating – Provides substantial longevity to corrosive environments and is conductive allowing safe grounding of cable armor. Meets new mandate set by the Environmental Protection Agency for elimination of heavy metal plating
  • High Performance Insert – High Perfomance Injection Molded Insert made from 30% GF Ultem® 2300 provides outstanding dielectric strength plus superior mechanical performance
  • Hi Performance Metal Alignment Sleeves – More robust than ceramic alignment sleeves
  • Hermaphroditic Dust Cap – Plug and/or receptacle dust caps connect together to prevent dust and moisture penetration during deployment
  • Field Repairable Using Existing Parts – Additional connector components (other than termini) are not required to perform field repair
  • Panel Mount Versions Available – In-line Panel mount with full environmental protection available as well as standard panel mount. Both designs feature industry first Blind Mate Assist Sleeves to aid user ergonomics.
  • Also Available in Stainless Steel and Brass – Allows the connector to be used in a variety of applications Oil, Gas, and Geoscience industries
  • Multiple Fiber Types – Supports Single mode, Mutlimode, and Plastic Optical Fiber (POF)


  • Next Gen Drilling Rig Control Systems
  • Mining
  • Industrial
  • Broadcast
  • Supports both multimode and single mode fiber
  • Expanded beam technology is less susceptible to dust and debris
  • Monolithic insert design facilitates cleaning
  • Hermaphroditic design enables daisy-chaining of cable assemblies to support varying distances
  • Non-contacting interface allows thousands of mating cycles
