ESPOO, Finland – Nokia has today announced a 10-year XGS-PON broadband equipment agreement with CityFibre including access nodes for its nationwide network of purpose-built Fibre Exchanges, fiber modems for customer homes and IP aggregation switches. Shipments will begin in Q4 2022.

CityFibre is building an open access network which will connect up to 8 million premises in 285 cities, towns and villages, reaching a third of the country. The Lightspan access nodes being supplied by Nokia as part of this solution will be used by CityFibre to offer its wholesale customers multigig residential broadband (up to 10Gb/s in both directions) and higher bandwidth services such as connecting Enterprises and providing backhaul for mobile networks.

Powered by Nokia's Quillion chipset, the same access nodes can be used for both XGS-PON and 25G PON (25Gb/s) on the same fiber, should CityFibre wish to do this in the future. Successful delivery of 25G PON for 5G transport using the same Lightspan access node has already been proven by CityFibre, Nokia and the University of Glasgow during a trial undertaken at the end of 2021.

Included in the deal:

  • Lightspan MF optical line terminals family (access nodes)

  • XS-010X-Q optical network terminations (fiber modems)

  • 7220 IXR-D3L IP Aggregation Switch

Usually located in fibre exchanges, Nokia's high-capacity optical line terminals are deployed for massive scale fiber roll-outs. They connect thousands of users via optical fiber, aggregate their broadband traffic and send it deeper in the network. The fiber access nodes can support multiple fiber technologies including GPON, XGS-PON, 25G PON and Point-to-Point Ethernet to deliver a wide range of services with the best fit technology.

Nokia ONT (Optical Network Termination) devices, or fiber modems, are located at the user location. They terminate the optical fibre connection and delivers broadband services within the user premises or cell sites.
