Transmitter Quality Metric for a standalone estimate of Coherent Optical Transmitter Performance

Abstract

Systems and methods for a transmitter quality metric (TQM) for a standalone estimate of coherent optical transmitter performance include, responsive to defining a reference receiver having known parameters, conducting noise loading on an output signal from a transmitter under test; utilizing the reference receiver and a calculation to determine a transmitter only required signal-to-noise ratio (RSNR) penalty, ΔRSNRtx; and providing the ΔRSNRtx as a transmitter quality metric (TQM). The transmitter only RSNR penalty is a difference between a RSNR to achieve a required pre-forward error correction (FEC) bit error rate (BER) and a theoretically required RSNR for an ideal modem.
