Options for Copper Beyond 112 Gbps

Future data center and high-speed computation require faster connectivity to meet the increasing set of applications and bandwidth. IEEE and OIF have developed 106-112 Gbps per lane electrical interface specifications P802.3ck1 and CEI-112 G2 for the 400 GbE system. To meet the next-generation system bandwidth requirement, industry and standard bodies recently kicked off new projects aiming at 800 GbE or even higher speeds beyond 1 TbE. So what comes next beyond 112 Gbps for electrical interfaces over copper (Cu) channels? Will it be 224 Gbps?
