Abstract:
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, the polymer sheath having a thickness in the range of 0.2 to 0.3 mm, wherein the bend resistant optical fibers in the micromodules can be accessed by tearing the micromodule sheath with a user's fingers, wherein each of the plurality of bend resistant optical fibers is comprises a glass cladding region surrounding and directly adjacent to a glass core region, wherein the cladding comprises a first annular portion having a lesser refractive index relative to a second annular portion of the cladding, 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.
