IEC 61300-3-3:2009(E) describes the procedure to monitor changes in attenuation and/or return loss of a component or an interconnecting device, when subjected to an environmental or mechanical test. The procedure may be applied to measurements on single samples or to simultaneous measurements on multiple samples, both at single wavelengths and multiple wavelengths, by using branching devices and/or switches as appropriate. This edition constitutes a minor revision. The change with respect to the previous edition is the structure of the document.
