Optical signal-to-noise ratio (OSNR) is a key metric of signal quality in DWDM networks. Over the years, the adoption of new technologies like reconfigurable optical add drop multiplexers (ROADM) and coherent transmission have rendered existing OSNR measurement methods obsolete.
In this webinar, we will first review the importance of OSNR as a key performance indicator of system performance. We will then discuss the existing OSNR methods, and why they cannot be used on live coherent signals. We will then introduce a novel method to measure non-intrusively the OSNR of 100G+ coherent signals, EXFO’s in-service Pol-Mux OSNR method.
