Ciena’s WaveLogic 6 Extreme coherent transceiver is the world’s first solution to deliver 1.6Tb/s per wavelength and ubiquitous unregenerated 800Gb/s connectivity across networks. It provides double the capacity within the same footprint, 50% power per bit reduction and 15% increase in spectral efficiency compared to the previous technology generation. WL6e integrates 3nm CMOS, 200 GBaud electro-optics, and new DSP innovations to deliver ultimate fiber capacity with less equipment. With WL6e delivering 1.6Tb/s across metro ROADM networks, 1.2Tb/s across 1000km distances, and 800G across the longest links, including transpacific, networks can now efficiently transport 400G/800G client connectivity across all applications.
