200g optical transmission can be technically feasible, and if you assume a certain amount of loss, is there a realistic PAM6 study?
Regarding Ethernet or 10GBASE-T, from 2017 [10GBASE-T, finally spread?] And delivered 11 times and 2 extra editions.However, the Ethernet of the copper line by twisted pairs is up to 10GBASE-T, and 25/40GBase-T has not yet been put into practical use.
[Access line 10Gbps road] may be a part of it, but here we will introduce “optical Ethernet” that uses optical fiber.

Furthermore, let's take a look at the 802.3 Beyond 400 GB/S Ethernet Study Group's meeting in May 2021.
Last time, although he wrote that there was not much proposal for Optic, Huawei's Maxim Kuschnerov and Lin Youxi showed the comparison of PAM4 and PAM6 in 200g lanes.
Regarding PAM4 and PAM6, "200g x 8 1.6Tbps, x 4 800Gbps is the transfer in 2023?Google presentations at the March meeting introduced in March were compared as follows.What was issued at the May meeting was the result of simulating this a little more finely.
3月のミーティングでは、“もしPAM6が消費電力を低く抑えられれば、PAM4とPAM6の使い分けも可能”とされていた
