Description
Bend-Insensitive Single-Mode Fiber is designed for superior performance, featuring excellent bend resistance to minimize signal loss, full compatibility with G.652 single-mode fibers, and broad wavelength transmission from 1260 to 1625 nm. It delivers low polarization mode dispersion (PMD) for high-speed, long-distance applications and ensures minimal micro-bending-induced attenuation across various cable types, including ribbon cables. With high fatigue resistance, this fiber guarantees a long service life even under small bending radii, making it an ideal choice for reliable, high-performance optical networks.
Application
G.657A1 Optical Fiber is suitable for optical cables of various structures, full-band transmission at 1260-1625nm, FTTH high-speed optical routing, optical cables with small bending radius requirements, small-sized optical cables and optical fiber devices, and requirements for using L-band.
