1. A breakout cable, comprising:
a polymer jacket; and a plurality of micromodules enclosed within the jacket, each micromodule having a plurality of bend resistant optical fibers and a polymer sheath comprising polyvinyl chloride surrounding the bend resistant optical fibers, wherein each of the plurality of bend resistant optical fibers is a multimode optical fiber, comprising a glass cladding region surrounding and directly adjacent to a glass core region, wherein the core region is a graded-index glass core region, wherein the refractive index of the core region has a profile having a parabolic or substantially curved shape, wherein the cladding comprises a first annular portion having a lesser refractive index relative to a second annular portion of the cladding, wherein the first annular portion is interior to the second annular portion, and wherein the cladding is surrounded by a low modulus primary coating and a high modulus secondary coating, and wherein when subjected to a corner bend load of six kilograms, delta attenuation at 850 nm in the cable due to the load is less than 0.4 dB. |
