Fiber optic fanout with intermediate portions and method of assembly
A main fanout includes a plurality of intermediate fanout devices that are connected to one another. Each intermediate fanout device can be assembled separately and then connected together to form the main fanout. Each intermediate fanout device is connected to an intermediate cable of a main cable and a plurality of optical fibers of each intermediate cable is positioned within at least one furcation tube. The plurality of optical fibers and at least one furcation tube are secured to a main body of each intermediate fanout device. Each intermediate fanout device includes a mating feature to connect to adjacent intermediate fanout devices with a like mating feature. The mating feature reduces relative movement between adjacent intermediate fanout devices.
1. An optical fiber cable comprising:
a main cable outer jacket having a first end and a second end, the main cable outer jacket having a slit extending from the first end of the main cable outer jacket to a termination location on the main cable outer jacket;
a slit cover positioned over the main cable outer jacket, the slit cover extending at least from the termination location to the first end of the main cable outer jacket to cover the slit;
a plurality of intermediate cables positioned within the main cable outer jacket, each of the plurality of intermediate cables containing a plurality of optical fibers within an intermediate cable outer jacket;
a main fanout including:
a plurality of intermediate fanout devices connected to one another, each intermediate fanout device being connected to an intermediate cable of the plurality of intermediate cables, the plurality of optical fibers of each intermediate cable being positioned within at least one furcation tube, wherein the plurality of optical fibers and at least one furcation tube is secured to a main body of each intermediate fanout device, each intermediate fanout device including a mating feature to connect to adjacent intermediate fanout devices with a like mating feature, wherein the mating feature reduces relative movement between adjacent intermediate fanout devices, and
wherein the main body of each intermediate fanout device includes a first end and a second end, the first end of the main body including an opening for receiving and, at least partially surrounding the intermediate cable of the plurality of intermediate cables, the second end of the main body including a v-shaped channel for positioning and securing therein, the plurality of optical fibers and at least one furcation tube, the plurality of optical fibers entering the v-shaped channel outside of the intermediate cable outer jacket and leaving the v-shaped channel disposed within the at least one furcation tube.
