Application Summary AI generated

This standard specifies the geometric, optical, and transmission characteristics of cut-off wavelength shifted single-mode optical fibres, designed to minimize bend loss and optimize performance in the 1550 nm wavelength region. It is applied in the manufacturing and testing of fibres used in long-haul, metropolitan, and access telecommunication networks, particularly for dense wavelength division multiplexing (DWDM) systems requiring low dispersion and high data rates.
