摘要

P To provide an optical signal quality-monitoring system, device, and method, and an optical signal transmitter and which can monitor a polarized state of each polarization channel without performing optical polarization separation of data modulated light. PSOLUTION: An optical signal quality monitor has a transmitter 10 and an optical signal quality monitor 30. The transmitter 10 includes a modulating section 11 for modulating a carrier light at a different frequency for each polarization channel and a polarization multiplexing section 12 that performs polarization multiplexing of the polarization channels and outputs them to an optical transmission line 20. The optical signal quality monitor 30 includes a polarization component detecting section 31 that extracts a light intensity component of each unit light frequency over the entire modulation bandwidth of a received data-modulated light signal and detects four kinds of polarization components for each light intensity component at each unit light frequency, a Stokes vector-calculating section 32 for calculating a Stokes vector by calculating the intensity of four kinds of light intensity polarization components, and an intensity extracting section 33 for extracting and from the Stokes vector, the intensity of a frequency modulation component added to each polarization channel.
