• Fibre optic interconnecting devices and passive components - Basic test and measurement procedures - Part 3-7: Examinations and measurements - avelength dependence of attenuation and return loss of single mode components

  Description:

  This part of IEC 61300-3 describes the various methods available to measure the wavelength dependence of attenuation A(λ) and return loss RL(λ ), 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(λ ) only; - Measurement of RL(λ ) oonly; - Measurement of A(λ ) and RL(λ ) at the same time. These measurements may be performed in one direction (unidirectional) or bi-directionally.
