摘要
An apparatus for detecting a light source causing OBI noise in an SCMA optical network. Subcarrier power meters in the apparatus measure powers of subcarrier signals obtained by filtering a multiplexed optical signal transmitted from the subscriber terminals. A OBI power meter measures OBI noise power from an output of an optical receiver that receives the multiplexed optical signal. A noise occurrence determination unit sequentially changes output powers of light sources in the subscriber terminals if the minimum SNR between the subcarrier signal powers and the OBI noise power is less than a reference SNR, and determines that a light source, which causes a change in the OBI noise power in response to the change in the output power of the light source, is an OBI-causing light source.
