Fibre optic communication subsystem test procedures - General communication subsystems. Central wavelength and spectral width measurement Ingestion-build-117251 procuring or installing diaphragm gas1 Scope This part of IEC 61280 provides definitions and measure procedures for several wavelength and spectral width properties of an optical spectrum associated with a fibre optic communication subsystem, an optical transmitter, or other light sources used in the operation or test of communication subsystems. The measurement is done for the purpose of system construction and or maintenance. In the case of communication subsystem signals, the optical
