An optical module comprises a case having a connection port for connection with an external optical fiber cable connector, and a locking member for locking the case in a cage for accommodating the case. The locking member is configured to lock the case in the cage when a connector is connected to the connection port after the case has been inserted into the cage up to a predetermined position, and to unlock the case from the cage when the connector is disconnected from the connection port. According to this optical module, the case can be locked in the cage through a simple operation of inserting the connector into the connection port after the case has been inserted into the cage.

Optical module capable of facilitating release from locking state with cage which accommodates optical module

If a user pushes an operating memberin a state in which a caseof an optical transceiveris locked in a cage, a leveris turned to the front of the optical transceiver. If the user pulls out the turned lever, a projection provided on an actuating pieceabuts a convex portionso that an end of the actuating pieceprojects below the case. If a plate spring portionof the cageis pressed and elastically displaced by the end of the actuating piece, a lock portionof the casecomes off a locking holeof the plate spring portion, and the optical transceivercan be pulled out of the cage

Mechanism for releasing lock between optical transceiver and cage, optical transceiver, communication apparatus and method of releasing lock between optical transceiver and cage

An optical module locking mechanism has locking means for locking a locking member swingably arranged in a case which forms part of an optical module and a cage for housing the case to each other, and a lever pivotably arranged on the case and capable of moving the locking member to release a locking state of the locking means. The locking means is released from the locking state by pulling the lever in a direction in which the optical module housed in the cage is drawn out of the cage. According to this optical module locking mechanism, the locking means can be released from the locking state by pulling the lever in the direction in which the optical module housed in the cage is drawn out of the cage, and the optical module can be removed from the cage by subsequently continuing to pull the lever in the same manner.
