Major Custom Cable’s expanded beam fiber optic assemblies have been designed for use in the most demanding harsh environment applications; we only use the highest grades of polyurethane tactical multi-fiber cable. Our expanded beam connectors are hermaphroditic which facilitates daisy-chaining and makes them ideal for tactical deployments such as satcom, military tactical communications, outside broadcast, petrochemical plant, mining, and offshore systems.

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 fiber optic connectors. Instead, the fiber is sealed behind a precision lens that increases the diameter of the beam by many orders of magnitude. In the mating connector, a second lens collects the light and focuses it into a second optical fiber to complete the connection.
