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:
