Abstract
An optical module has a lever for bending a spring plate possessed by a cage for accommodating a case of the optical module in a direction in which a retaining hole formed through the spring plate comes off a latch formed on the case. The lever has a shaft pivotably supported on the case, a tongue disposed on one side of the shaft, and an actuator disposed on the opposite side of the shaft with respect to the tongue. The lever pivotally moves about the shaft in response to a movement of the tongue toward the case, causing the actuator to press the spring plate to bend in the foregoing direction. A user can readily release the latch by moving the tongue toward the case, and withdraw the optical module from the cage through a simple manipulation of pulling the case out while holding the case and tongue together.
