Crosslake Fibre

Overview

Crosslake Fibre is a submarine cable system spanning 59 kilometers, connecting Toronto, Ontario, Canada, and Buffalo, New York, United States. Fully operational since 2019, the cable is owned and operated by Crosslake Fibre. This system provides a direct fiber-optic link between two major metropolitan areas, facilitating high-speed data transmission across the Canada-U.S. border. Its strategic design enhances connectivity for businesses, data centers, and telecommunications networks in both regions.

As a relatively short submarine cable, Crosslake Fibre exemplifies the use of advanced fiber-optic technology to bridge international borders efficiently. It plays a vital role in supporting economic and technological collaboration between Canada and the United States, particularly in sectors reliant on low-latency communications.

Route and Landings

Crosslake Fibre connects Toronto, Ontario, Canada, and Buffalo, New York, United States, via a submerged route across Lake Ontario. Toronto, located on the northern shore of the lake, is Canada's largest city and a global financial hub. Buffalo, situated on the southeastern edge of Lake Ontario, is an industrial and commercial center with strategic access to the Midwest region of the United States.

The cable’s path across Lake Ontario avoids overland routes, which can be more vulnerable to environmental disruptions or logistical challenges. By leveraging the lake as a natural corridor, the cable ensures a direct and secure connection between the two cities. This route also minimizes latency, making it particularly beneficial for industries requiring rapid data exchange, such as finance, technology, and logistics.

Toronto’s landing point ties into the city’s extensive telecommunications infrastructure, while Buffalo’s landing integrates with regional networks that serve both local and interstate data demands. Together, these landing points strengthen cross-border connectivity and support economic activities on both sides of the lake.

Ownership and History

Crosslake Fibre is the sole owner and operator of the cable system. The company specializes in developing and managing fiber-optic infrastructure, with a focus on providing low-latency connectivity between key markets. The Crosslake Fibre cable was completed and ready for service in 2019, marking a significant milestone in enhancing Canada-U.S. telecommunications links.

The decision to build a submarine cable across Lake Ontario reflects the growing demand for direct, high-speed communication pathways between Toronto and Buffalo. Historically, cross-border data exchange relied heavily on terrestrial networks, which often involved longer routes and higher latency. By deploying this submarine cable, Crosslake Fibre has addressed these challenges, offering a more efficient solution for international connectivity.

Since its launch, the cable has contributed to the development of digital infrastructure in the region, supporting industries such as finance, manufacturing, and technology. Its ownership structure ensures streamlined operations and maintenance, allowing Crosslake Fibre to focus on delivering reliable services to its customers.

What Our Measurements Show

Our live monitoring of the Crosslake Fibre cable reveals consistent performance across 138 measured corridors. The best round-trip time (RTT) recorded is 7 milliseconds, while the average RTT stands at 24 milliseconds. These metrics highlight the cable’s low-latency capabilities, which are essential for applications requiring real-time data transmission.

The cable’s short length of 59 kilometers contributes to its efficiency, as shorter routes typically experience less signal degradation and lower latency. This makes Crosslake Fibre particularly suitable for industries such as financial trading, cloud computing, and telecommunications, where milliseconds can significantly impact operations.

Additionally, our probes indicate stable performance across varying traffic conditions, underscoring the reliability of the system. The consistent measurements reflect the robust design and maintenance of the cable, ensuring uninterrupted connectivity between Toronto and Buffalo. By providing a direct link across Lake Ontario, Crosslake Fibre plays a pivotal role in supporting seamless cross-border communication.
