所有设备+线都要正确接地
而且Cat.8布线长度按标准也只有3m+24m+3m
最高速率也就是40Gbps
个人觉得还是考虑放光缆作主干的好 |

非常正确放光缆作主干 100g不是问题

Terabit Ethernet or TbE is Ethernet with speeds above 100 Gbit/s. 400
Gigabit Ethernet (400G, 400GbE) and 200 Gigabit Ethernet (200G, 200GbE)[1]
standards developed by the IEEE P802.3bs Task Force using broadly similar
technology to 100 Gigabit Ethernet[2][3] were approved on December 6, 2017.[
4][5] In 2016, several networking equipment suppliers were already offering
proprietary solutions for 200G and 400G.[5]
The Ethernet Alliance's 2019 technology roadmap expects speeds of 800 Gbit/s
and 1.6 Tbit/s become IEEE standard after 2020 possibly in 2025.[6][7]
Doubling to 800 GbE is expected to occur after 112 Gbit/s SerDes become
available. The Optical Internetworking Forum (OIF) has already announced
five new projects at 112 Gb/s which would also make 4th generation (single-
lane) 100 GbE links possible.[8]
