Data centres adopt optical technology to reduce power consumption

Data‑centre operators are increasingly replacing traditional copper cabling with optical‑based interconnects to reduce energy consumption and boost bandwidth. Optical links, which transmit information as light through fiber‑optic cables, consume markedly less power than copper because they eliminate the need for electrical amplification and can carry higher data rates over longer distances without signal degradation. Industry reports indicate that the shift can cut power draw for networking equipment by up to 30 percent while simultaneously expanding the aggregate capacity of server farms to meet growing demand for cloud services and high‑performance computing.

The transition is being driven by the rapid rise in data traffic and the need for more sustainable infrastructure. Major cloud providers and enterprise data‑centre owners have begun retrofitting existing facilities and designing new builds around dense wavelength‑division multiplexing (DWDM) and other photonic technologies that enable multiple data streams on a single fiber. Analysts expect the adoption of optical interconnects to accelerate as component costs fall and standards mature, positioning light‑based networking as a cornerstone of future data‑centre efficiency and scalability.
