Abstract

The present invention provides a performance monitoring device, an optical signal network with performance monitoring, and a performance monitoring method. The performance monitoring device (100) comprises a coherent receiver (10), an analog-to-digital-converter, ADC (20), a digital signal processing module, DSPM (30), and a noise correction module, NCM (40),the receiver (10) having a second bandwidth that is smaller than the first bandwidth (BW1) such that the receiver (10) is configured to output an electrical analog signal (72) with the second bandwidth based on the received optical signal (71) having the first bandwidth,the ADC (20), being configured to generate from the electric analog signal (72) a digital input signal (73) with the second bandwidth ;the DSPM (30) being configured to generate a raw performance monitoring metric, RPMM (74), based on the digital input signal (73);wherein the NCM (40) is configured to generate a performance monitoring metric, PMM (75), based on the digital input signal (73) by compensating distortion in the RPMM (74) caused by the coherent receiver (10) having a smaller bandwidth than the optical signal (71).
