Application Summary AI generated

GB/T 18478-2001 specifies the technical requirements, test methods, and inspection rules for fiber optic circulators, which are non-reciprocal optical devices that direct light signals sequentially from one port to another. This standard is applied in the telecommunications industry for manufacturing and testing circulators used in dense wavelength division multiplexing (DWDM) systems, optical amplifiers, and fiber optic sensor networks to ensure signal routing integrity and isolation performance. It provides a benchmark for quality control and compatibility in both domestic Chinese telecom equipment production and procurement contexts.
