Hi CASPERites, I believe that 40 Gbps Ethernet interoperates rather transparently with 10 Gbps. Because the 40 Gbps is arranged as four x 10 G lanes, so its possibly to break a 40 QSFP port into four 10 SFP+ with a suitable breakout cable. Or with proper packet addressing via a network switch with 40 and 10 ports.
Likewise 100 Gbps interoperates with 50/25 easily. And 400 with 200 and 200, and so on. The question arose in a meeting today whether it’s a simple matter to transform a 100 Gbps Ethernet stream into 10 Gbps streams, 10 of them or whatever? There are various switches on the market with both 100 and 10 Gbps ports, but not clear whether these re distinct networks, or whether they transparently interoperate. Can someone offer input as to whether transforming 100 Gbps QSFP28 into multiple 10 Gbps SFP+ links is easily accomplished in a suitable switch? Or a complicated endeavor? Hope this is clear.
