optical connector
A demountable device for attaching a cabled or uncabled optical fiber to another, or to an active device such as a transmitter.
Note 1: A connector is distinguished by the fact that it may be disconnected and reconnected, as opposed to a splice, which permanently joins two fibers.
Note 2: Optical connectors are sometimes erroneously referred to as “couplers. ” Such usage is incorrect and is to be avoided. [After FAA]
