適用范圍：The purpose of this part of IEC 61300 is 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.
