Product Overview
Winner industrial single-mode bare optical fiber is designed for high-reliability deployments in thermally demanding settings such as factory automation, outdoor telecom infrastructure, medical imaging systems, and energy-sector networks. Built on a precision 9/125 μm core/cladding platform with a 250 μm dual-layer UV-cured acrylate coating, the fiber maintains geometric integrity and optical performance across its full operating spectrum (1260–1625 nm).
With chromatic dispersion of <18 ps/(nm·km) at 1550 nm and ultra-low attenuation (≤0.20 dB/km @1550 nm, ≤0.34 dB/km @1383 nm), it supports uncompensated 10G transmission over 80 km and is fully compatible with 25G/100G industrial Ethernet standards. The fiber’s core-cladding concentricity error (≤0.6 μm) and cladding non-circularity (≤1.0%) ensure minimal splice loss and high connector repeatability—even after thermal cycling. Its cutoff wavelength of ≤1260 nm guarantees true single-mode operation, while robust coating adhesion enables reliable handling in field installations.
