G652D 48.8KM 50.4KM per spool SM BARE FIBER can custom length
G.652.D is currently the most widely used standard single-mode optical fiber, extensively used in backbone networks, metropolitan area networks, access networks, and long-distance communication networks. Its zero-dispersion wavelength design is around 1310 nm, and it also performs excellently in the 1550 nm transmission window. G.652.D fiber supports an extended wavelength range from 1260 nm to 1625 nm, making it suitable for CWDM, DWDM, FTTH, and high-capacity optical transmission systems. With its low attenuation, excellent splice compatibility, and proven long-term reliability, G.652.D remains the industry standard for modern fiber optic infrastructure worldwide.
Product Overview
G.652.D is a standard low-water-peak single-mode optical fiber widely used in long-haul, metro, access, and backbone communication networks. It complies with ITU-T G.652.D and provides excellent transmission performance over the 1260–1625 nm wavelength range, including O, E, S, C, and L bands. Compared with earlier G.652 fiber types, G.652.D features reduced water-peak attenuation, enabling efficient CWDM and DWDM transmission. It offers low attenuation, high bandwidth capacity, and reliable long-distance performance. Fully compatible with existing single-mode fiber infrastructure, G.652.D is one of the most commonly deployed fibers in modern optical communication systems.
