kSARIA Expanded Beam Fiber Optic AssemblieskSARIA expanded beam fiber optic assemblies have been designed for use in the most demanding harsh environment applications including: military tactical communications, outside broadcast, petrochemical plant, mining, and offshore systems.

Using a precision lens system, expanded beam connectors increase the diameter of the beam through the connector’s optical path.


  • Expanded beam connectors are less susceptible to insertion loss due to dust and debris than physical contact connectors.
  • There is no physical contact of meeting termini as in butt-joint fiber optic connectors.
  • Expanded beam connectors can have >1000 mating cycles.
  • The expanded beam connectors are hermaphroditic which facilitates daisy-chaining and makes them ideal for tactical deployments such as satcom, military and broadcast applications


  • MIL-DTL-83526 Specification
  • Singlemode and Multimode options
  • Field repairable: EB insert & shell parts replaceable / re-useable
  • 1, 2 & 4 channel plugs and bulkheads
  • Low insertion loss / high return loss
  • 90° Backshell options for plug and bulkhead
