1 Scope
2 General description
3 Apparatus
3.1 Optical source (S)
3.2 Temporary joint (TJ)
3.3 Terminations (T)
3.4 Detector (D)
4 Procedure
Aims to measure the directivity of light between channels of a multiport non-wavelength-selective MxN fibre optic branching device. The directivity is defined as the fraction of the light that goes from an input path to another input optical path, normally isolated from the previous one.
