The Corning SMF-LS Optical Bare Fiber 13 km CPC6 is a single-mode fiber engineered for long-distance telecommunications and high-bandwidth data transmission. The fiber delivers low attenuation across C and L bands with a CPC6 protective coating that enables reliable stripping and integration into diverse cable architectures—tight buffer, ribbon, loose tube, and slotted core designs. Operating from −60 °C to +85 °C with stable performance across temperature and humidity cycling, this fiber meets ITU-T G.652.B standards and supports modern DWDM systems.
