400G, 800G, and Terabit Pluggable Optics: What You Need to Know - BRKOPT-2699#

Mark Nowell (Cisco), Errol Roberts (Cisco)

• Why: Optics is a listed core interest, and this is the standards-and-roadmap session covering the full 400G→1.6T transition.
• What: Current 400G pluggable technologies and applications, next-gen form factors for 800G and 1.6T (including breakout use cases), the new 800Gb/s and 1.6Tb/s Ethernet standardization work, and optical co-packaging developments for integrating optics into ASICs (from abstract only).
• How: Covers both coherent and non-coherent optics, what's driving each development, and the system/network implications of adopting them.
• Where applicable: Broadly applicable industry roadmap rather than a Cisco product pitch (Mark Nowell is a long-time IEEE 802.3 participant); co-packaging and LPO/LRO implications matter to any high-density DC design.
