Abstract
Abstract A rotate-and-pull mechanism for fiber optic modules. The mechanism having a lever-actuator to unlatch and withdraw a fiber optic module from a cage assembly or a module receptacle. The lever-actuator pivotally couples to the fiber optic module so that when lever-actuator is rotated about its pivot point, the lever-actuator causes a pivot-arm actuator to release the fiber optic module from the cage assembly. The pivot-arm actuator further including a keeper to engage into a latch in the cage assembly. A bracket, which may be coupled to the fiber optic module, provides a flexible arm portion to provide a counteracting force when the pivot-arm actuator rotates to release the fiber optic module from the cage assembly. The bracket may include a slot through which the keeper on the pivot-arm actuator may move through as the pivot-arm actuator pivots.
