Abstract

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 By pulling the lever-actuator away from the cage assembly, the fiber optic module is withdrawn from the cage assembly.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.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 106 words
A fiber optic module comprising: a nose receptacle including a fiber optic cable receptacle to receive one or more fiber optic cable plugs, a lever-actuator to release the fiber optic module from a cage assembly using a rotational action, a spring to bias the lever-actuator to an engaged position, and a second actuator coupled to the lever-actuator, the second actuator to release a keeper from a latch to release the fiber optic module in response to a rotational action on the lever-actuator; and a printed circuit board including one or more electro-optic transducers to convert optical signals into electrical signals or electrical signals into optical signals.
Claim 2
Dependent Claim 106 words
A fiber optic module comprising: a nose receptacle including a fiber optic cable receptacle to receive one or more fiber optic cable plugs, a lever-actuator to release the fiber optic module from a cage assembly using a rotational action, a spring to bias the lever-actuator to an engaged position, and a second actuator coupled to the lever-actuator, the second actuator to release a keeper from a latch to release the fiber optic module in response to a rotational action on the lever-actuator; and a printed circuit board including one or more electro-optic transducers to convert optical signals into electrical signals or electrical signals into optical signals.
Claim 3
Dependent Claim 33 words
The fiber optic module of claim 1 wherein, the fiber optic module is a small form pluggable (SFP) fiber optic module and the cage assembly is a small form pluggable (SFP) cage assembly.
Claim 4
Dependent Claim 23 words
The fiber optic module of claim 1 further comprising: a housing to couple to the nose receptacle and cover the printed circuit board.
Claim 5
Dependent Claim 21 words
The fiber optic module of claim 3 wherein, the housing is shielded to protect the printed circuit board from electromagnetic interference.
Claim 6
Dependent Claim 21 words
The fiber optic module of claim 1 wherein, the lever-actuator includes one or more pins to rotationally engage the nose receptacle.
Claim 7
Dependent Claim 21 words
The fiber optic module of claim 1 wherein, the lever-actuator includes one or more holes to rotationally engage the nose receptacle.
Claim 8
Dependent Claim 21 words
The fiber optic module of claim 1 wherein, the lever-actuator includes one or more pins to rotationally engage the nose receptacle.
Claim 9
Dependent Claim 21 words
The fiber optic module of claim 1 wherein, the second-actuator slides to release the fiber optic module from the cage assembly.
Claim 10
Dependent Claim 21 words
The fiber optic module of claim 1 wherein, the second-actuator includes grooves to slideably couple the second-actuator to the nose receptacle.
Claim 11
Dependent Claim 21 words
The fiber optic module of claim 1 wherein, the second-actuator includes rails to slideably couple the second-actuator to the nose receptacle.
Claim 12
Dependent Claim 32 words
The fiber optic module of claim 1 wherein the spring is a biasing spring, a tension spring, a torsion spring, a wind-up spring, or a coil spring to apply the bias force.
