An optical fiber connector has three major components: the ferrule, the connector body and the coupling mechanism. Generally made from ceramic, metal or high quality plastic, the ferrule is a thin structure (often cylindrical) that holds the glass fiber. The connector body is a plastic or metal structure that holds the ferrule and attaches to the jacket and strengthens members of the fiber cable itself. And the coupling mechanism is a part of the connector body that holds the connector in place when it gets attached to another device.
