Data centres look to fibre optics and photonics to reduce power consumption
Überblick
Data centre developers are increasingly turning to photonics—using light instead of electrons for internal data transmission—to reduce power consumption and cooling requirements. While traditional data centres rely heavily on copper wiring, transitioning to fibre optics can significantly lower heat generation and energy use. However, the industry still faces manufacturing challenges, supply chain complexities, heat sensitivity issues, and the need for technicians to learn new installation skills.
Wichtige Punkte
- Typical 100MW data centres use around 400 tonnes of copper, with portions dedicated to electrical infrastructure, servers, and network wiring.
- Photonics uses light (photons) instead of electricity (electrons) to transmit data, generating far less heat and reducing energy needed for cooling.
- AI chip giant Nvidia has supported the technology, and experts note that photonics is moving from the laboratory into widespread commercial application.
- Transitioning to optical networking presents challenges, including managing manufacturing costs, global supply chains, and the heat sensitivity of optical components.
- Engineers and technicians must learn new handling skills, such as avoiding tight bends when installing fibre optic cables.
- Older silicon manufacturing equipment from previous generations of processors can be repurposed to help lower the cost of producing photonics at scale.
