Bending insensitive single-mode fiber has various characteristics of optical fibers and better resistance to macro bending. It is a low water peak fiber that is not sensitive to bending and can fully utilize the O-E-S-C-L band (1260-1625nm) for transmission. eBay ® The anti bending performance of optical fibers not only ensures the availability of the L-band, but also makes it easy to install, such as in the installation of switch boxes. For indoor optical cables, optical fibers are suitable for small bending radii and tight installations. The minimum bending radius can reach 10mm.
