Field trial of real-time single-carrier and dual-carrier 400G terrestrial long-haul transmission over G.654.E fiber

摘要

The world's longest terrestrial G.654.E fiber link with a total length of 1539.6 km is performed. Error-free transmission of real-time single-carrier and dual-carrier 400G over 603-km and 1058.9-km G.654.E fiber with an OSNR margin of more than 5 dB are demonstrated, respectively.
