Polish service provider Netia conducted the first field trial of Nokia's Photonic Service Engine 3 (PSE-3) super coherent technology over a live production network. In the trial, wavelengths driven by the Nokia PSE-3 and operating at 62-68 Gbaud traversed Netia's flex-grid infrastructure in 75GHz channels. Network paths currently supporting 100G and 200G wavelengths were shown to support of greater than 300G and 500G respectively, more than doubling...
