100G is not quite state-of-the-art anymore, but it is what is being deployed. This chip supports 10G ports, and can do 400Gbps through it, but does not support 100Gbps front-panel ports from what I can see.

There are field trials and pre-prod switch/route chips and optical/DWDM gear that support 400G Ethernet using 56Gbps SerDes. This chip uses older 12.5Gbps SerDes, current-gen 100Gbps stuff uses 28Gbps SerDes.
