Application Summary AI generated

GB/T 9771.2-2000 specifies the geometric, optical, transmission, and mechanical characteristics of cut-off wavelength shifted single-mode optical fibres used in telecommunications. It applies to fibres designed for long-haul, high-bit-rate transmission systems operating in the 1550 nm wavelength window, where shifting the cut-off wavelength reduces bending losses. This standard is used by fibre manufacturers and network operators to ensure consistent performance in dense wavelength division multiplexing (DWDM) and submarine cable applications.
