“There is probably more technical risk in 400 gigabits than any of the historical data-rate jumps we have seen,” says Rafik Ward, vice president of marketing at Finisar.

PAM-4, a higher order modulation scheme, used for the electrical and optical client interfaces is another challenge at 400-gigabit. The use of PAM-4 requires a slight increase in bandwidth, says Brooks, and introduces a loss that requires compensation using forward error correction (FEC). “Four-hundred-gigabits is the first Ethernet technology where you always have FEC on,” he says.

But the large-scale data centre players are not interested in the CFP8 which they see as too bulky for the data centre. Instead, Amazon, Facebook, and equipment vendor Cisco Systems are backing the higher-density QSFP-DD, while Google and Arista Networks are proponents of the OSFP.

“The data centre players don’t need IEEE standardisation, they need the lowest cost and the most compact form factor,” says Lumentum’s Collings.

Wow, does this article just scream "LWLG P2IC Platform" which is now in the process of scaling to a 100Gbs standalone proto, and based on our knowledge of the materials response time being a femptosecond, LWLG can scale into the Terabit range as a standalone

WoW just Wow !!
