Description
Non-Dispersion-Shifted Single Mode Fiber is optimized for 10–40 Gb/s transmission systems in both the C-band and L-band. It features low attenuation, dispersion, polarization mode dispersion (PMD), and zero dispersion slope, ensuring excellent system performance. Additionally, it provides low bend-induced loss at the 1550 nm wavelength and the more sensitive 1625 nm window, making it ideal for high-speed, long-distance communication networks.
Application
G.655C Optical Fiber can be applied to high-speed, single/multi-channel, long-distance digital transmission systems; various optical cable structures, including optical fiber ribbon cables, loose tube stranded cables, skeleton cables, central bundle tube cables and tight-buffered cables.
