If there is one sentence that captures the industry direction revealed by the first group of papers at #
ECOC# 2026, it is this: the most important change is no longer simply pushing optical communications from 800G to 1.6T, and then from 1.6T to 3.2T.
Instead, the industry is beginning to confront a much broader question: as each lane becomes faster, optical engines move closer to compute silicon, and the number of fibers continues to increase, how can the entire system still be manufactured at scale while keeping power consumption, yield, packaging complexity, testing requirements, and cost under control?
This is what makes ECOC 2026 particularly important.
