Application Summary AI generated

This standard specifies the optical transmission test procedures for optical circuit boards that lack input/output fibres, focusing on measuring insertion loss and return loss within the board's internal waveguide structures. It is applied in the manufacturing and quality control of optical circuit boards used in telecommunications, data centers, and high-speed optical interconnects where integrated photonic components are tested without external fibre pigtails.
