+Bending insensitive single-mode fiber has two excellent characteristics: excellent bending resistance and low water peak, which can fully utilize the O-E-S-C-L band (1260-1625nm) for transmission. The anti bending performance of fiber optic cables not only ensures the use of the L-band, but also makes it easy to install, especially in fiber to the home networks where the bending radius of the fiber optic cable can meet the requirements for laying along the smallest wall corner. Moreover, the mode field diameter (MFD) of the+fiber is consistent with the standard G.652 single-mode fiber, which results in low connection losses, including fusion losses and insertion losses, with G.652 fiber. This fiber optic cable can fully meet the network's requirements for capacity and flexibility.
