Product Overview
Winner single-mode bare optical fiber features a standard 9/125 μm core/cladding geometry with a 250 μm UV-cured acrylate coating, engineered to meet or exceed ITU-T G.652.D specifications—the most widely deployed single-mode fiber standard globally. With ultra-low water peak attenuation (≤0.34 dB/km @1383 nm), it enables full-spectrum transmission from 1260 nm to 1625 nm (O-, E-, S-, C-, L-, and U-bands), making it ideal for CWDM, DWDM, 5G fronthaul, and high-capacity data center interconnects.
The fiber exhibits exceptional geometric control: core-cladding concentricity error ≤0.6 μm and cladding non-circularity ≤1.0%, ensuring low splice loss (<0.03 dB typical) and high connector yield. Its cutoff wavelength of ≤1260 nm guarantees true single-mode operation across all operating bands. With a macrobend radius of ≥4 m and robust performance over -40°C to +85°C, Winner single-mode fiber maintains signal integrity in demanding indoor and outdoor environments. The product supports data rates from 1G up to 800G and beyond, limited only by transceiver technology—not the fiber itself.

Standards & Compatibility
Winner single-mode fiber complies with ITU-T G.652.D, IEC 60793-2-50 B1.3, and Telcordia GR-20-CORE requirements. It is fully compatible with standard SMF connectors (LC, SC, FC), fusion splicers, and all major transceiver standards including 10GBASE-LR, 100GBASE-LR4, 400GBASE-FR4, and OTU4. For bend-sensitive applications, G.657.A1/A2 variants are available with enhanced macrobend performance down to 7.5 mm radius.
