Telesat Lightspeed network combines the global reach of satellites with leading-edge network architecture to provide true carrier-grade connectivity

OTTAWA, Canada, and HANOVER, Md., U.S.A. – October 12, 2021 – Telesat, one of the world’s largest and most innovative satellite operators, is deploying Routing and Switching platforms from Ciena (NYSE: CIEN) for its Telesat Lightspeed terrestrial backhaul network. Ciena’s advanced routing and switching technology will ensure that Telesat has a modern, cost-effective network that takes advantage of emerging technologies including network functions virtualization (NFV) and edge computing to efficiently support both existing and future customer requirements.

The Telesat Lightspeed network will initially be comprised of 298 advanced Low Earth Orbit (LEO) satellites that seamlessly integrate with terrestrial networks. LEO satellites operate 25 to 30 times closer to the Earth’s surface than traditional satellites and can process data with ultra-low latency—typically on par with fiber-optic speeds, even to the world’s most rural and remote locations.

Ciena is supplying hardware and software that will provide high-speed, high-capacity connections to governments, telcos, mobile operators, and other enterprise customers for the delivery of 5G, cloud computing, video, and other bandwidth-intensive broadband services.

Telesat will use Ciena’s 3926 and 5170 platforms to provide agile, assured MEF-compliant services at its points of presence (PoPs), as well as terrestrial connectivity to as many as 50 Earth-based landing stations. The Ciena platforms have advanced quality of service (QoS) mechanisms, including hierarchical ingress metering, that will provide Telesat with fine-grained control of network traffic. Ciena’s Manage, Control and Plan (MCP) domain controller will provide highly effective software control and automation to drive business agility.

Additionally, Telesat is utilizing Ciena Services for terrestrial network design, implementation, and testing.

Executive Comments:

• “As the leading provider of aggregated, global Tier 1 carrier connectivity, Ciena’s field-proven routing and switching technology will ensure flexible, reliable connectivity between our Earth station antennas and Points of Presence throughout the world. The seamless integration of on-ground data networks with our advanced Telesat Lightspeed satellites will ensure unmatched speed and performance for our global enterprise and government customers.”
