Migrating to 400G? Choosing the Right Option
Migrating to 400G? Choosing the Right OptionAs customers deploy 400G connectivity, they are transitioning from 25/100G connectivity to 100/400G connectivity for the different tiers of the network. Before making a decision, you should carefully consider your technical needs and budget with these parameters in mind: Reach: the distance you need to transmit dataPower ConsumptionFlexibility – bending ratio. This is particularly important in tight spacesCost Let us
