What is an Expanded Beam Connector?

Expanded Beam uses a lens in front of the fiber to collimate the light coming out of the fiber. The lens expands the size of the beam from 9 um to 285 um for SM. Expanded Beam connectors have distinct advantages and disadvantages compared to Physical Contact connectors. Read our White Paper on Expanded Beam Connectors for more in-depth details.

Amphenol Fiber Systems International (AFSI) is the only manufacturer that offers a complete suite of both Expanded Beam and Physical Contact connectors. Contact your AFSI sales representative to discuss which option is best suited for your application
