  • Patent number: 6994478
    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 By pulling the lever-actuator away from the cage assembly, the fiber optic module is withdrawn from the cage assembly.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.

  • Patent number: 6974265
    Abstract: Fiber optic modules having a pull-actuator to unlatch and withdraw (i.e. unplug) it from a cage assembly or a module receptacle. The pull-actuator includes a pull-tab, an arm or push rod, and a catch to couple to a pivot-arm actuator. The pivot-arm actuator pivotally latches to the pull-actuator and to the cage assembly or module receptacle. The pull-actuator makes it easy to de-latch and unplug a fiber optic module. A nose grip is further provided to pull the fiber optic module away from the cage or module receptacle. A belly-to-belly mounting configuration is introduced for the pull-release fiber optic modules.

  • Patent number: 6692159
    Abstract: Fiber optic modules including a bail-latch to disengage and withdraw the fiber optic module from a cage assembly or module receptacle. In one embodiment, the fiber optic modules further include a spring to bias the bail-latch into an engaged position and one or more electro-optic transducers to convert optical signals into electrical signals or electrical signals into optical signals. In another embodiment the fiber optic modules further include an engaging triangle to engage an opening in a latch of the cage assembly which is responsive to the bail-latch. In yet another embodiment, the fiber optic modules include a sliding actuator having a butt surface at one end and at least one ramp at an opposite end, instead of an engaging triangle. A belly-to-belly mounting configuration is introduced for the bail-latch release fiber optic modules.
