Abstract
1 Scope This part of IEC 61280 provides definitions and measurement 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. This document also provides definitions and measurement procedures for side-mode suppression ratio and signal-to-source spontaneous emission ratio. 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.
NOTE Different properties can be appropriate to different spectral types, such as continuous
spectra characteristics of light-emitting diodes (LEDs), as well as multilongitudinal-mode
(MLM), multitransverse-mode (MTM) and single-longitudinal mode (SLM) spectra, which
are characteristic of laser diodes (LDs).
