Bend-insensitive single-mode fiber has various characteristics of the fiber, and has better resistance to macrobending. It is a bend-insensitive low-water-peak fiber, which can fully utilize the O-E-S-C-L band (1260 ~ 1625nm) transmission. The bending resistance of the fiber not only ensures that the L-band is available, but also easy to install, such as the installation of a switch box. For indoor fiber optic cables, optical fibers are suitable for tight installations with small bend radii. The minimum bending radius can reach 10mm.
Applications
? Optical cable suitable for various structures
? Excellent performance in O-E-S-C-L band
? FTTx high-speed optical routing
Product Standards
YOFC? bend-insensitive single-mode fiber meets or exceeds ITU-T G.652.D / G.657.A1 optical fiber technical specifications and IEC60793-2-50 B1.3 / B6.a1 optical fiber technical specifications.
Features
? Low attenuation meets the requirements of O-E-S-C-L working band
? In the case of small radius bending, the fiber can well suppress bending loss
? Low bending loss meets the requirements of higher cable design requirements including fiber optic ribbons
