Passive Optical Network (PON), cloud, and 5G continue to catalyze the growth of network-edge bandwidth needs. The industry is well past 1G and 10G and has moved onto 100G for edge applications, which is a deployment priority from now through 2023. The 100G transition at the edge will, in turn, catalyze bandwidth growth in the network core, where 400G has been deployed. The 400G capability will be extended into the aggregation segment of the network to handle the growth of 100G access links.
