Application Summary AI generated

This standard specifies the test and measurement procedures for determining the directivity of fibre optic branching devices, such as couplers and splitters. It is applied in the telecommunications industry to ensure that these passive components minimize signal leakage between input and output ports, which is critical for maintaining network performance and preventing crosstalk in optical distribution systems. The standard is used during product qualification, manufacturing quality control, and compliance testing for fibre optic networks.
