What this means for you

Nothing to act on from this. It is a general description of a shift, with no supplier, efficiency figure or date, so there is nothing to evaluate or buy against. If you plan data-centre power budgets, watch for a named optical interconnect with a measured joules-per-bit figure; none is given here.

Data centres are replacing the copper wiring that carries data between machines with links that move it as light, according to a BBC Technology report published on 22 September 2026. The reasons given are lower power consumption and more capacity. The source text available to us names no supplier, product, measurement or deployment date, so the scale of the change cannot be checked from it. On what is available, this describes a direction of travel rather than a result.

What the sources say

  • BBC Technology — Poses the copper-to-light shift as an open question rather than reporting a measured result.
