Sumitomo Electric Single Mode Fiber DSF is a 25.2 km dispersion-shifted optical fiber engineered for long-haul backbone and metro networks. This germanium-doped silica core fiber delivers low attenuation across C, L, and O bands while maintaining controlled dispersion characteristics. The 9/125 µm core/cladding geometry pairs with dual acrylate protective coatings in 250 µm nominal diameter, enabling direct integration with standard splicing and connectorization equipment.
