Fiber connectors are often used as the terminations of optical fiber cables in order to provide nonpermanent connections between fiber-coupled devices. A fiber optic connector is a flexible device that connects fiber cables requiring a quick connection and disconnection. Optical fibers terminate fiber optic connections to fiber equipment or join two fiber connections without splicing. Most optical fiber connectors are spring-loaded, so the fiber faces are pressed together when connectors are mated. An optical fiber connector terminates the end of an optical fiber, and enables quicker connection and disconnection. The connectors mechanically couple and align the cores of fibers so that light can pass.
