Corning Single Mode fiber DSF Optical Bare Fiber 14900 m / 15km

Corning Single Mode Dispersion-Shifted Fiber (DSF) is a 14,900 meter bare optical fiber engineered to minimize dispersion effects and maintain signal integrity across extended transmission distances. The fiber features a 9 µm core, 125 µm cladding, and 250 µm acrylate coating, delivering low attenuation across the C and L bands while meeting ITU-T G.652.D and G.657.B3 standards.
