Abstract:
A breakout cable includes a polymer jacket and a plurality of micromodules enclosed within the jacket. Each micromodule has a plurality of bend resistant optical fibers and a polymer sheath comprising PVC surrounding the bend resistant optical fibers. Each of the plurality of bend resistant optical fibers is a multimode optical fiber including a glass cladding region surrounding and directly adjacent to a glass core region. The core region is a graded-index glass core region, where the refractive index of the core region has a profile having a parabolic or substantially curved shape. The cladding includes a first annular portion having a lesser refractive index relative to a second annular portion of the cladding. The first annular portion is interior to the second annular portion. The cladding is surrounded by a low modulus primary coating and a high modulus secondary coating.
