The IEEE P802.3dj Task Force has advanced its initiative to define Ethernet standards at 200 Gbps, 400 Gbps, 800 Gbps, and 1.6 Tbps by moving to the Working Group Ballot phase. This progression marks a significant step toward finalizing specifications that utilize 200 Gbps per-lane signaling for both electrical and optical interfaces, aiming to meet the escalating bandwidth demands of data centers and AI/ML infrastructures.
The P802.3dj project encompasses a range of physical layer (PHY) specifications, including 800 Gbps and 1.6 Tbps Ethernet over copper and single-mode fiber, with reach capabilities extending up to 40 km. It also addresses 200 Gbps and 400 Gbps Ethernet standards where applicable, ensuring a comprehensive approach to next-generation Ethernet interconnects. The project has adopted baselines for various media types, including backplane, copper cable, and single-mode fiber, and has incorporated objectives for long-reach applications, such as 800 Gbps over single-mode fiber up to 20 km.
The IEEE P802.3dj Task Force’s efforts are part of a broader strategy to support the evolution of Ethernet standards in response to the growing needs of high-performance computing environments. The task force has considered numerous technical contributions and made key architectural decisions to facilitate the development of these high-speed Ethernet standards. The next steps involve generating draft versions of the standard and conducting reviews to refine the specifications further.
