100G transmission revolutionized long-haul DWDM transport by dramatically increasing capacity and lowering cost per bit transmitted. But network operators can no longer rely on 100G alone to keep up with surging bandwidth demand. Platforms powered by the Nokia Photonic Service Engine 2 Super Coherent (PSE-2s) digital signal processor (DSP) double long-haul and ultra-long-haul capacities. They can help you continue decreasing cost per bit transmitted and expand the capacity of your long-haul DWDM systems.
