To convert an Inon style fiber cable to Sea & Sea and adaptor connector is needed and the Xit 404 Fiber Optic Connector, Inon to Sea & Sea Kit does just that. It consists of two parts that snap together to capture the end on the fiber cable. A small set screw secures the cable in the connector. Once assembled you can now insert the fiber into a Sea & Sea style opening. The Fiber Optic Connector is made from durable Red plastic.
