Fiber Optic Connectors

Size 12 | Expanded Beam Connector


The Size 12 | expanded beam connector  is particularly well suited for tough environments and use in indoor and outdoor multimode applications. These contacts have a robust, reliable optical fiber connection. Its transmission performances are unaffected even in tough environments and when subjected to mechanical stresses. Thanks to the expansion of the optical beam, these expanded beam connectors are insensitive to contamination. The Size 12 expanded beam contact is suitable for use in circular connectors but can also be used in hybrid systems
