ActiveSpecifications for optical fibre test methods—Part 44: Measurement methods and test procedures for transmission and optical characteristics—Cut-off wavelength
光纤试验方法规范 第44部分：传输特性和光学特性的测量方法和试验程序 截止波长
Application Summary AI generated
This standard specifies the measurement method for determining the cut-off wavelength of single-mode optical fibres, which is the wavelength above which only the fundamental mode propagates. It is applied in the telecommunications industry for quality control and performance verification of optical fibres used in long-haul and metro network cables. The test ensures that fibre links operate in single-mode condition to minimize modal dispersion and signal loss.
