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.<\/p>\n

The measurement is done for the purpose of system construction and\/or maintenance. In the case of communication subsystem signals, the optical transmitter is typically under modulation.<\/p>\n

\n

NOTE Different properties may be appropriate to different spectral types, such as continuous spectra characteristic of light-emitting diodes (LEDs), and multilongitudinal-mode (MLM), multitransverse-mode (MTM) and single-longitudinal mode (SLM) spectra, characteristic of laser diodes (LDs).<\/p>\n<\/blockquote>\n
