DETAILED DESCRIPTION

[0024] FIGS. 1A and 1B depict an environment for employing a breakout cable assembly in an example embodiments. In FIG. 1A, a breakout cable assembly 100 is used to connect first equipment 10 to a plurality of second equipment 20, located at various heights in an equipment rack. In FIG. 1B, the second equipment 20 is located in separate racks. In the example in FIGS. 1A and 1B, the first equipment is a network switch 10 and the second equipment includes servers 20. It is understood that a variety of types of equipment may be used with the breakout cable assembly 100, and embodiments are not limited to the equipment depicted in FIGS. 1A and 1B. The breakout cable assembly 100 is connected to the first equipment 10, passes through a cable management area 102 and then is connected to each second equipment 20. The distance between the cable management area 102 and each second equipment may be, for example but not limited to, 0.5 meters.

[0025] FIG. 2 depicts a breakout cable assembly 100 in an example embodiment. A first connector 104 is used to connect to the first equipment 10. In the example in FIG. 2, the first connector 104 is a QSFP connector. It is understood that other types of connectors may be used as the first connector 104. Exiting the first connector 104 are four cable legs 106. The cable legs 106 include optical fiber. The cable legs 106 extend from the first connector 104 to the second connector 108. Each cable leg 106 includes two or more optical fibers, defining send and receive channels for the first connector 104. In the example in FIG. 2, the second connector 108 is a SFP connector. It is understood that other types of connectors may be used as the second connector 104.

[0026] Each cable leg 106 includes a first cable segment 110 and a second cable segment 112, connected by an intermediate connector 114. The first cable segment 110 is terminated at the first connector 104 and the intermediate connector 114. The second cable segment 112 is terminated at the intermediate connector 114 and the second connector 108. In the example of FIG. 2, the intermediate connector 114 includes a third connector 116 terminated on the first cable segment 110 and a fourth connector 118 terminated on the second cable segment 112. In the example in FIG. 2, the third connector 116 and the fourth connector 118 are LC connectors, mated through an adapter 120. It is understood that the intermediate connector 114 may be implemented in other manners, such as a plug and outlet and is not limited to LC connectors. In example embodiments, the third connector 116 and the fourth connector 118 are multi-fiber push on (MPO) connectors.

[0027] The length of the second cable segment 112 may be equal to the distance between the cable management area 102 and the second equipment 20 (e.g., 0.5 meters). The length of the first cable segment 110 may be variable, depending on the location (e.g. height) of the second equipment 20 in the equipment rack.

[0028] The intermediate connector 114 allows for disconnection of a faulty or damaged second cable segment 112 and/or faulty or damaged second connecter 108, without disconnecting any other second cable segments 112. This reduces service interruptions on second equipment 20.

[0029] FIG. 3 depicts a breakout cable assembly 200 in an example embodiment. In FIG. 3, the intermediate connector 114 and second cable segment 112 are similar to those in FIG. 2. The first cable segment 110 is divided into a first section 230 and a second 232 by a second intermediate connecter 214. The first section 230 is terminated at the first connector 104 and the second intermediate connector 214. The second section 232 is terminated at the second intermediate connector 214 and the intermediate connecter 114. The second cable segment 112 is terminated at the intermediate connector 114 and the second connector 108. In the example of FIG. 3, the second intermediate connector 214 includes a fifth connector 216 terminated on the first section 230 and a sixth connector 218 terminated on the second section 232. In the example in FIG. 3, the fifth connector 216 and the sixth connector 218 are LC connectors, mated through an adapter 220. It is understood that the second intermediate connector 214 may be implemented in other manners, such as a plug and outlet. In example embodiments, the fifth connector 216 and the sixth connector 218 are multi-fiber push on (MPO) connectors.

[0030] In FIG. 3, the length of the first section 230 of the first cable segment 110 may be equal to the distance between the cable management area 102 and the second equipment 20 (e.g., 0.5 meters). The length of the second section 232 of the first cable segment 110 may be variable, depending on the location (e.g. height) of the second equipment 20 in the equipment rack.

[0031] FIG. 4 depicts a breakout cable assembly in an example embodiment. The embodiment of FIG. 4 is similar to that in FIG. 3. One difference in FIG. 4 is the use of a splitter 300 at an output of the first connecter 104. The splitter 300 is terminated to the output (e.g., fibers) of connector 104. The splitter 300 divides the output of the first connector 104 into the four first sections 230 of the first cable segments 110. As shown in FIG. 4, the splitter is an multi-fiber push on (MPO) to LC splitter. It is understood that the splitter 300 may interface with various connector configurations, and embodiments are not limited to MPO to LC. The splitter 300 may also be used in the embodiment of FIG. 2, at the output of first connecter 104.

[0032] FIG. 5 depicts a breakout cable assembly in an example embodiment. In FIG. 5, the splitter 300 of FIG. 4 is used with the cable legs 106 of FIG. 2.

[0033] FIG. 6 depicts a breakout cable assembly in an example embodiment. In FIG. 6, a splitter 400 is connected to the first connector 104. The splitter 400 is terminated to the output (e.g., fibers) of connector 104. The splitter 400 divides an MPO output of the first connector 104 into at least two MPO cable legs 106. The intermediate connectors 114 are implemented using MPO connectors.
