Application Summary AI generated

This standard specifies the geometric, optical, and transmission characteristics of dispersion-shifted single-mode optical fibres designed for long-haul, high-bit-rate telecommunication systems. It is applied in the manufacturing, testing, and procurement of optical fibres used in dense wavelength division multiplexing (DWDM) networks where zero-dispersion is shifted to the 1550 nm window to minimize signal distortion. The standard ensures compatibility and performance consistency for fibres deployed in backbone and submarine cable systems.
