G.657.A1. Bending Insensitive Single-mode Optical Fiber

G.657.A1, the bending insensitive single-mode optical fiber, not only has outstanding bending insensitive characteristics, but also has excellent loss characteristics at 1310 nm and 1550 nm dual wavelengths, which is conducive to extending access network coverage.

    Application Scenarios

    > Gigabit broadband home
    > 5G pre-network construction
    > Big data center & computer interconnection

    Performance Features

    > Low loss & bending insensitive
    > Two optional diameters: 245 μm (standard) & 200 μm (optional)
    > Optimized MFD and precise geometric properties
