An optical connector with memory function comprises memory function for storing respective identification information in order to readily and exactly perform separate control of respective control steps and further to obtain convenient handling of connectors. The optical connector with memory functionof the present invention is characterized by a memory function capable of untouchably performing, from outside thereof, writing-in and reading-out of necessary information. The memory function has a structure mounted on or mountable on the outer construction of a housing accommodating therein the optical connection portion of an optical connector plug in the optical connector with memory function.

Optical connector with memory function

A non-lock detector switch is provided on or near an adapter to be switched by a connector plug when the connector plug with memory function unit is coupled to the adapter having an antenna for accessing to the memory function unit. Accordingly, connection state of each connector can be directly and simultaneously detected by the switching operation of the detector switch at a time preceding a little from a time when the antenna detects the memory function unit just having closed to a position opposed to the antenna. This is useful for exactly and detecting without delay the complete coupling state of each one of a number of adapters in distinction from the incomplete coupling state of any one of adapters.
