Request InfoNokiaESPOO, Finland, March 7, 2023 — The PSE-6s super-coherent photonic service engine from Nokia reduces power consumption for optical transport networks. The engine supports the efficient delivery of high-speed services including 800-Gbit Ethernet over distances of 2000 km and beyond. A unique chip-to-chip interface enables deployment in pairs to power 2.4-Tb/s coherent transport solutions, allowing network operators to efficiently transport any combination of high-speed client services. CSTAR silicon photonics are integrated with 5-nm coherent digital signal processors. Operating at 130 Gbaud, the PSE-6s powers coherent...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 4/2/2024Optical Transport SolutionsThe optical transport solutions from Nokia are meant for optical transport, IP routing, and PON applications and include coherent optical transceivers, a photonic engine, and a multihaul transceiver....Photonics.com 7/14/2022Pluggable Coherent TransceiverADVA Optical Networking SE and II-VI Inc. have announced a 100ZR pluggable coherent transceiver for the optical network edge.
