Abstract

Rotate-and-pull mechanisms for fiber optic modules. The rotate-and-pull mechanisms have 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 the second actuator to release the fiber optic module from the cage assembly. The lever-actuator includes an actuating-tab to cause the second actuator to move when the lever-actuator is rotated. By pulling the lever-actuator away from the cage assembly, the fiber optic module is withdrawn from the cage assembly. A belly-to-belly mounting configuration is introduced for the rotate-and-pull release fiber optic modules.

the pull-arm is a bail-latch.

16. The lever-actuator of claim 1 wherein

the actuating tab to rotate and cause a fiber optic module to disengage from a cage assembly in response to a rotation of the lever arm.

17. The lever-actuator of claim 16 wherein

the lever arm has a second end opposite the first end, the second end of the lever arm being free to rotate away from the fiber optic module.

18. The lever-actuator of claim 16 wherein

the actuating tab is stiff and rigidly coupled to the lever arm.

19. A lever-actuator for fiber optic modules, the lever-actuator comprising:

a lever arm having a first end;

a pivoting fastener coupled to the first end of the lever arm; and

a sliding-actuator to couple to the first end of the lever arm and to slide and disengage a fiber optic module from a cage assembly in response to a rotation of the lever arm.

20. The lever-actuator of claim 19 further comprising:

an actuating tab coupled to the first end of the lever arm, the actuating tab to rotate and couple to the sliding-actuator to slide the sliding-actuator and disengage the fiber optic module from the cage assembly in response to the rotation of the lever arm.

21. The lever-actuator of claim 20 wherein

the actuating tab prevents the lever arm from rotating further once it reaches a limit point.
