Application Summary AI generated

This standard specifies test methods for measuring polarization mode dispersion (PMD) in single-mode optical fibres, which is critical for high-speed digital transmission systems. It is applied in the telecommunications industry for quality assurance and performance verification of fibre optic cables used in long-haul networks and data centers. The standard ensures that PMD-induced signal distortion remains within acceptable limits for reliable high-bandwidth communication.
