Abstract
We propose a novel method for optical signal-to-noise ratio (OSNR) monitoring by the correction to the error of OSNR in high speed coherent optical communication systems. We calculate the total power and the total noise power by the real and imaginary part of the coherent detection signal. Then, the error of OSNR is corrected by a polynomial function. The simulation results demonstrate that, with the input power of 0.0dBm and 2.0dBm of 15-35GB QPSK optical fiber communication systems, the error of estimated OSNR is in the range of ±1dB with the reference OSNR of 15-25dB.
