Description

IEC 61300-3-20 Ed. 1.0 b – Fibre optic interconnecting devices and passive components – Basic test and measurement procedures – Part 3-20: Examinations and measurements – Directivity of fibre optic branching devices

Applies to measuring the directivity of light between channels of a multiport non-wavelength-selective MxN fibre optic branching device. The directivity is the fraction of light that goes from one input path to another path, normally isolated from each other.
