Patent ID: 8582941

Claim:
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 PVC surrounding the bend resistant optical fibers, the polymer sheath having a thickness in the range of 0.2 mm to 0.3 mm, 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; wherein when the cable is subjected to a corner bend tie down test at two tie down bend locations of 25.4 mm radius, delta attenuation at 850 nm in the cable due to the bend is less than 0.05 dB.
