Description
Non-dispersion Single-mode Fiber is designed for high-speed, long-distance transmission, offering low attenuation, dispersion, and polarization mode dispersion (PMD). These characteristics make it an excellent choice for reliable and efficient performance in advanced optical communication systems.
Application
G.652B Optical Fiber is suitable for various cable structures, including ribbon cables, loose-tube stranded cables, skeleton cables, central tube cables, and tight-buffered cables.
