Using a precision lens system, expanded beam connectors increase the diameter of the beam through the connector’s optical path. Consequently, expanded beam connectors are less susceptible to insertion loss due to dust and debris than physical contact connectors. In addition, there is no physical contact of mating termini as in butt-joint fibre optic connectors. Thus, expanded beam connectors can have >1000 mating cycles. Also, these expanded beam connectors are hermaphroditic which facilitates daisy-chaining and makes them ideal for tactical deployments such as satcom, military and broadcast applications.

Diamond Defence’s expanded beam cable assemblies are available in single mode or multimode configurations and are offered with a wide variety of cable, connector configurations and reel options. Contact a Diamond Defence representative to find out more about how Diamond Defence can customize an expanded beam MIL- DTL-83526/20 and /21 assembly for your application.
