The LUCENT BARE SINGLE MODE FIBER 20Km is a precision-engineered optical fiber delivering low-loss signal transmission across extended distances. This bare fiber maintains full compatibility with SMF-28 specifications and operates across the 1310 nm and 1550 nm wavelength regions for telecommunications and data communications infrastructure. Constructed with mechanically strippable dual acrylate coating (Corning CPC6) and manufactured via Outside Vapor Deposition, the fiber provides exceptional attenuation performance and polarization mode dispersion characteristics suitable for long-haul network deployments.
