Fiber Couplers

Shop fiber optic couplers for connecting compatible fiber patch cables, jumpers and equipment interfaces. Also called fiber adapters, mating sleeves or fiber connector couplers, these components align two matching optical connectors to create a continuous fiber connection.

Find LC-to-LC fiber couplers for single-mode fiber networks, including simplex and duplex configurations. Flanged and low-profile no-flange designs support different mounting requirements within fiber panels, wall plates, test setups and network enclosures.

Fiber couplers with ceramic alignment sleeves help position connector ferrules within the adapter interface. These components are used throughout broadband networks, data centers, enterprise systems, DAS installations, 5G infrastructure, fiber-to-the-home networks and fiber testing applications.

Browse additional fiber optic adapters, fiber jumpers and fiber patch cables. Pair your couplers with fiber termination boxes and distribution enclosures for organized panel-mounted connections.
