Product Overview
Winner G.652.D single-mode optical fiber is the industry-standard solution for metropolitan, access, and long-haul networks requiring cost-effective, high-capacity transmission. Engineered with a low water peak profile, it enables seamless full-spectrum operation from O- to L-band (1260–1625 nm), supporting CWDM, DWDM, and future-proof coherent transmission systems.
The fiber exhibits true zero chromatic dispersion near 1310 nm and ultra-low attenuation (≤0.33 dB/km @1310 nm, ≤0.20 dB/km @1550 nm), significantly reducing the need for amplification or dispersion compensation over medium distances. With polarization mode dispersion (PMDQ) < 0.2 ps/√km and stringent geometric tolerances, it ensures signal integrity for 10G/25G/100G Ethernet, OTN, and 5G transport applications.
