The Corning SMF-28e Optical Fiber is a single-mode fiber engineered for long-haul telecommunications, FTTH deployments, ISP backbones, and data center interconnects. This 10 km spool meets ITU-T G.652.D specifications and incorporates bend-insensitive technology for reliable performance in installations with constrained routing. The fiber delivers minimal attenuation across C, L, and O bands while maintaining excellent chromatic dispersion characteristics across extended wavelength ranges.
