It seems that 25GbE is more preferred and accepted by end users, compare with 10GbE and 40GbE. 1.Why Choose 25GbE? While 10GbE is fine, it cannot efficiently for the next-generation Clould and web-scale environments. And 40GbE, isn't cost-effective or power-efficient. So, that's why we need 25GbE. 2.The Cost of 25GbE Wiring Is Lower 40GbE has to be cooperated with MPO fiber to transmit, it would c...
