Abstract: 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.

Abstract: The present invention provides an optical transceiver which can be miniaturized while having a number of electronic components mounted on an electrical circuit board thereof. An optical transceiver comprises: a substrate having at least one electronic component mounted thereon; a base comprising a receptacle for connecting an optical connector; and a case which houses the substrate. The substrate is substantially perpendicular to an upper surface or a lower surface of the case.

Abstract: If a user pushes an operating member 50 in a state in which a case 11 of an optical transceiver 1 is locked in a cage 2, a lever 22 is turned to the front of the optical transceiver 1. If the user pulls out the turned lever 22, a projection provided on an actuating piece 28 abuts a convex portion 35 so that an end of the actuating piece 28 projects below the case 11. If a plate spring portion 18 of the cage 2 is pressed and elastically displaced by the end of the actuating piece 28, a lock portion 17 of the case 11 comes off a locking hole 19 of the plate spring portion 18, and the optical transceiver 1 can be pulled out of the cage 2.

Abstract: 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.
