ABSTRACT:
An optical connector plug according to the present invention which is joined to a front end of an optical fiber cord covering an optical fiber and which is removably inserted to one end of an optical adapter having a locking member for locking the optical connector plug in an engaged state, includes an inserted portion removably inserted to one end of the optical adapter, a plug body joined to a front end of the optical fiber cord, a locking portion formed between the plug body and the inserted portion and locked by the locking member of the optical adapter, and a rotational phase reference surface formed on the plug body away from the locking portion. The optical connector plug according to the present invention can be applied to APC optical connector plug, secure high reliability for optical cross-connecting, and also reduce cost.
