Learn about coherent optical transceiver technology in this 23-minute NANOG conference talk that explores the implementation of 400G coherent technology in pluggable optical transceivers. Dive into Nokia's implementation and examine potential interoperability issues addressed by the OIForum, with a focus on interface parameters for transport systems, routers, and switches using coherent pluggable transceivers. Explore key concepts including direct detection, polarization, quadratic amplitude modulation, signal-to-noise ratio, constellation diagrams, and digital diagnostic monitoring. Understand coherent parameters, chromatic dispersion, Q factors, and application modes while getting insights into future developments with 800G and 1.6T formfactors. Speaker Thomas Weible from Flexoptix provides practical knowledge for network engineers and administrators working with advanced optical networking technologies.
