Data Centers Turn to Light-Based Tech to Cut Energy Use
Facilities are replacing copper wiring with photonic technology to reduce power consumption and expand capacity.
Data centers around the world are increasingly replacing traditional copper wiring with light-based technology in an effort to reduce energy consumption and boost operational capacity, according to a BBC News report. The shift reflects mounting pressure on the industry to address its substantial and growing electricity demands.
Copper wire has long served as the backbone of data center infrastructure, carrying electrical signals between servers and networking equipment. However, as demand for computing power accelerates — driven by cloud services, artificial intelligence workloads, and streaming — operators are confronting the physical and energy limitations of conventional electrical interconnects.

Light-based, or photonic, technology transmits data using pulses of light rather than electrical current, a method that can move information faster and with significantly less heat generation. Reduced heat output is particularly consequential for data centers, where cooling systems can account for a substantial share of total energy use.
The transition represents both a technical and financial undertaking for facility operators, who must weigh the upfront costs of new photonic components against long-term savings in power bills and the ability to handle greater data throughput without expanding physical footprints. Industry observers note that the economics are becoming increasingly favorable as photonic components grow more mature and cost-competitive.
The broader context is one of urgency: data centers are under scrutiny from governments and utilities over their surging electricity consumption, making efficiency improvements a strategic as well as environmental priority for operators. Continue reading at BBC News.
