The 500G DWDM Muxponder supports a variety of optical modulation formats, including DP-64QAM modulation to support single-carrier 400G, DP-8QAM for 200G, and 4-dimensional set partition QPSK (4D-SP-QPSK) for transcontinental 100G. The two-slot card supports two line ports with independently provisionable operating mode, fully tunable across extended C-Band. On the client side, 5xCFP4 clients support 100GBASE-LR4, 100GBASE-SR4, and OTU4. Nokia's WaveTracker technology offers end-to-end photonic OAM.
Judge's comment: "I believe this product will be the first for both dual-carrier PSE, single-carrier 400G, while in a reasonably dense footprint. It may also be the first commercial product to operate at 45 Gbaud."
