AbolishedSpecifications for optical fibre test methods - Part 49: Measurement methods and test procedures for transmission and optical characteristics - Differential mode delay
光纤试验方法规范 第49部分：传输特性和光学特性的测量方法和试验程序-微分模时延
Application Summary AI generated
This standard specifies the test method for measuring differential mode delay in multimode optical fibres, which quantifies the variation in propagation time between different optical modes. It is applied in the telecommunications industry for quality control and performance verification of multimode fibres used in high-speed local area networks and data centers. The procedure ensures accurate bandwidth characterization, critical for optimizing fibre performance in short-reach, high-data-rate transmission systems.
