Telus Launches 125km Undersea Internet Cable to Boost Connectivity

Telus Unveils New Submarine Fiber Optic Cable in Quebec
Telus has recently revealed the launch of a new submarine fiber optic cable that stretches nearly 125 kilometers, linking Sept-Îles to Sainte-Anne-des-Monts in Quebec. This enterprising project began back in November and aims to enhance communication services across the region.
Boosting connectivity for Eastern Communities
The newly installed fiber optic cable is set to significantly improve telecommunications for communities located east of Baie-Comeau. Telus emphasizes that this cable serves as a crucial backup route, ensuring uninterrupted telecommunication services even if there are issues with terrestrial networks. Remarkably, despite its length, the cable has a diameter of just 3 centimeters and is buried approximately one and a half meters beneath the ocean floor. Historically, cables like this have proven to last several decades.
Innovative Installation Techniques for Marine Protection
During the installation process, Telus implemented advanced detection systems utilizing thermal imaging and artificial intelligence (AI) technology to safeguard marine life. This commitment reflects their dedication not only to enhancing connectivity but also to protecting local ecosystems during construction activities.
A Commitment to Environmental restoration
Looking ahead, Telus plans environmental restoration efforts scheduled for spring and summer 2026. these initiatives aim to protect the shoreline of the St. Lawrence River while promoting regrowth among local plant species such as sea lyme-grass.
A Collaborative Investment for Future Growth
This project represents a joint investment exceeding $20 million, with support from the Government of Canada contributing up to $7.5 million towards its realization. The submarine fiber optic cable aligns with Telus’ broader mission of connecting various regions across Canada and is part of an impressive billion investment plan slated through 2029.
