In optical networking conversations around the world, 400G is a hot topic. According to leading Cloud Service Providers (ICPs) and industry analysts, 400G technology is ramping at least twice as fast as 100G. Driving the demand for more network capacity are the usual suspects, 5G, data center/cloud computing, and high-definition video transmission. However, what’s driving 400G deployments is not 400G, but the sub-rates like 200GE, 100GE, 25GE, etc.
Get the latest poster from VIAVI which displays the technical aspects of line-rates from 25GE to 400GE, the lower layers.
