Broadband’s sustainability reckoning is happening inside the fiber rollout

Sustainability in telecom is often discussed in abstract targets and distant timeframes. But for Openreach, the company building one of the largest full‑fiber networks in Europe, the challenge is far more immediate and tangible. “We install millions of these devices every year,” said Trevor Linney, network technology director at Openreach, referring to the optical network terminals installed inside customers’ homes. “So it rapidly translates into a very material benefit when you reduce plastics or improve energy efficiency.” Openreach has already passed 23 million U.K. premises with fiber and is pushing toward 30 million. That scale makes even small design changes consequential. The ONT—which converts optical fiber to Ethernet—became a focal point for sustainability improvements because it sits at the intersection of manufacturing materials, packaging, transport, and in‑home energy use, said Linney.
