An optical fiber connector constitutes a fiber-to-fiber interconnection and aligns the fiber core of two optical fibers. Due to the fast development of optical nets a variety of optical fiber connectors are available. The main difference is in the dimensions and the mechanical grip. Standard connectors are the LC, FC, ST and SC connectors. If the fiber end is angled to reduce back reflections this is usually described by adding APC (Angled Physical contact Connector) to the name. Optical fibers An optical fiber or fibre is a transparent thin fiber, usually made of glass or plastic, for transmitting light. ...

• FC (Ferrule Connector) has a floating ferrule that provides good mechanical isolation. However, it is screwed into contact which can induce scratches on the fiber.

• SC connector offers excellent packing density, and its push-pull design resists fiber end face contact damage during connection.

Common types of fiber optic connectors include biconic, D4, ESCON, FC, FDDI, LC, loopback, MTP, MT-RJ, MU, SC, SMA and ST.

In general the insertion loss should not exceed 0.75 dB and the return should not be higher than -20dB. Typical insertion repeatability, i.e. the difference in insertion loss between one plugging and another, is 0.2 dB.
