Data Centres Turn to Light to Cut Power Use
Data centres are switching from copper wires to optical technology to save power and increase capacity, according to a BBC Technology report.
Data centres are exploring a shift from copper wiring to optical technology in an effort to reduce power consumption and boost capacity, according to a BBC Technology report published on September 22, 2026.
The report indicates that the move involves using light-based systems instead of traditional copper cables. This change is being considered as a way to address the growing energy demands of data centres.
While the report suggests that optical technology could help cut power use, it does not provide specific figures or details on the scale of potential savings. The transition is presented as an ongoing development in the data centre industry.
Further information on the implementation and impact of this switch has not been provided in the source material. The BBC Technology report highlights the interest in optical solutions as a means to improve efficiency.
