Advances in 400 Gigabit Ethernet Field Trials
Lynn E. Nelson · Optical Fiber Communication Conference · 2018
We review two recent 400G field trials in AT&T's network. We demonstrated 400Gb/s Ethernet end-to-end circuits, with CFP8 client interfaces and dual-wavelength 16QAM or single-wavelength 32QAM lineside, and SDN-controlled creation, deletion, and re-routing of 400G services.
