Project Description

FS12 Pierside 12-Channel Fiber Optic Connector

Physical Contact Connectors – Hermaphroditic

The Amphenol Fiber Systems International (AFSI) FS12 fiber optic connector is for harsh environment, broadcast and pierside applications. This connector is available in either single mode or multimode and uses field-proven MIL-PRF-29504 termini.

The 12-channel FS12 Pierside connector design provides flexibility for current and future Navy communication requirements both afloat and ashore. This connector is also ideal for high fiber count tactical broadcast networks.

Removable termini, qualified to MIL-PRF-29504 specifications, enable quick connector reconfiguration and field maintainability.


  • Hermaphroditic design: enables plug-to-plug or plug-to-receptacle connectivity
  • Rugged design: FS12 Pierside connector handles the rigors of deployment and harsh environment conditions for both industrial and military applications
  • Environmentally sealed connector: ensures environmental integrity
  • Military qualified MIL-PRF-29504 /14 & /15 Termini: takes advantage of tightly toleranced commercial ceramic ferrules and alignment sleeves allowing either single mode or multimode use
  • Removable insert cap: enables ease of socket termini cleaning
  • Captive insert cap screw: prevents loss of screw during cleaning or repair
  • Sealed termini: keeps the optical path clear under extreme environmental conditions
  • Field repairable using existing parts: additional connector components (other than termini) are not required to perform field repair


  • Umbilical cables used to interface between shore and ship networks
  • Broadcast
  • US Army, Navy, Air Force and Marine Corps tactical and strategic deployments
  • Oil, gas and geoscience industries
  • Industrial
