To connect two fiber optic cables, you’ll need a coupler. The CPLR-SCSC-FD is a handy way to do this. It connects two fiber optic cables with duplex SC to duplex SC connectors to extend the cable run. This coupler is built from high-quality lightweight plastic for reliability and long life. It supports a duplex fiber connection and features alignment sleeves to ensure signal integrity. Dust caps are included to keep out contaminants and particles when not in use.
