Fibre optic interconnecting devices and passive components. Basic test and measurement procedures. Examinations and measurements - Directivity of fibre optic branching devicesWhat is BS EN 61300 3 20 Fibre optic branching devices about? BS EN 61300 3 20 is a part of an international multi series standard that discusses fibre optic interconnecting devices and passive components. BS EN 61300 3 20 measures the directivity of light between channels of a multiport non wavelength selective M x N fibre optic branching device. Directivity is defined as the fraction of the light that goes from an input path to another input optical
