FiberHome® bending insensitive single-mode fiber encompasses all the features of low water peak dispersion unshifted single-mode fiber and provides good resistance to macro-bending. It has low macro-bending sensitivity and low water-peak level. It is comprehensively optimized for use in O-E-S-L band(1260-1625nm).
It offers good resistance to additional losses due to low macro-bending in the 1600nm wavelength region. This not only supports L-band applications but also allows for easy installation without excessive care when storing the fiber, for example, in splicing cassettes. For cable use inside buildings, the fiber supports installation with small cable bending radii and compact organizers. The bending induced loss at 1625nm no more than 0.5 dB for one wind with 10nm radius.
