33.180.20 Fibre optic interconnecting devices
IEC 61300-3-7: 2009 describes the various methods available to measure the wavelength dependence of attenuation A(l) and return loss RL(l), of single-mode passive optical components (POC) used in fibre-optic (FO) telecommunications. It is not, however, applicable to dense wavelength division multiplexing (DWDM) devices. Measurement methods of wavelength dependence of attenuation of DWDM devices are described in IEC 61300-3-29. Definition of WDM device types is given in IEC 62074-1. Three measurement cases are herein considered:
Measurement of A(l) only;
Measurement of RL(l) only;
Measurement of A(l) and RL(l) at the same time.
These measurements may be performed in one direction (unidirectional) or bi-directionally. This second edition cancels and replaces the first edition published in 2000. It constitutes a technical revision. Changes from the previous edition of this standard are to reflect changes made to IEC 61300-1 and covers unidirectional and bi-directional methods of measurement.
