400G, 800G, and Terabit Pluggable Optics:

Equipment and electrical serdes can evolve through 3 generations (25 Gb/s, 50 Gb/s or 100 Gb/s) without changing the optical interface that interconnects your equipment.

Inside an AI server today, the GPUs talk to each other through copper

Inside an AI server today, the GPUs talk to each other through copper cables and small pluggable optical modules. Starting in the second half of 2026, that wiring gets replaced by lasers
