Nokia and Google Fiber trial 50G PON – first in the U.S.

Nokia and Google Fiber have tested 50Gb/s PON over Google’s fiber optic network.  The partners say it’s the first live network demonstration of that technology in the US.  The trial comes after last year’s partnership between Nokia and Google Fiber to enhance broadband services with 25G PON.

As fiber facility based network operators continue to push for increased speeds and reliability from their broadband networks, 50G PON acts as a catalyst to meet connectivity demands – unleashing further opportunity for growth and innovation. Capable of being easily built upon existing 25G PON solutions, it also enables flexibility for the operators to add future 50Gb/s with the fiber in place.

Nokia claims to be the only vendor that can support all next-generation PON options, with 10G and 25G products available today, 50G in trials, and 100G PON as a technology demonstrator.

With Nokia’s Lightspan fiber access platform, operators can choose a PON solution that best meets a specific use case or business need. The 50G PON trial with Nokia showcases how Google Fiber is looking at the future and what’s needed for new broadband services that foster innovation and growth. Leveraging Nokia’s fiber solution, Google Fiber was able to simultaneously run 10/25G PON along with 25/50G PON broadband service over its fiber network. This showcased the network flexibility and scalability it can deliver to keep pace with the growing demand for multi-gigabit services in the future. Google Fiber is already at the forefront of the multi-gigabit evolution, having launched the first 25G PON commercial services with Nokia in 2023.

Liz Hsu, Senior Director, Product & Billing, at Google Fiber, said: “We are always looking for ways to push the capabilities of our fiber network to deliver the best possible experience to our customers. This test with Nokia builds on the 25G PON deployment we announced together last year, paving the way for future improvements to our network that enhance customer experience in terms of speed, reliability, innovation and support for future business cases that have yet to be defined.”

Geert Heyninck, vice president of broadband networks at Nokia, said: “Service providers need to be able to select the right technology, based on their needs and business case. It is why we already offer 10G and 25G today, are trialing 50G, and developing 100G – ultimately leading to a full range of PON technologies that can be mixed and matched on the same platform and the same fiber. Our expansive toolkit of fiber solutions allows Google Fiber to future-proof their network and flexibly address their evolving network demands.”

  • GFiber Labs is the second 50G PON trial Nokia has run globally in the past 4 months and the first to occur in the U.S.
  • Nokia is the first vendor to show all PON technologies (10G, 25G & 50G) in a live fiber network.
  • Nokia is the number one vendor for XGS-PON technology globally according to 2023 market share figures from Dell’Oro and Omdia.
  • There are more than 12 operators around the world who are already gaining the benefits of 25G PON, and the eco-system is maturing with more than 5 ONT vendors bringing 25G PON solutions to the market.
  • Some operators currently deploying 25G PON include Google Fiber, EPB, Vodafone Qatar and OGI.
  • The ecosystem for 25G PON is mature, with more than 60 operators, system vendors, chipset, and optical suppliers part of an MSA focused on standardizing and accelerating the technology.
  • Nokia is a key contributor to 50G PON industry standard and introduced the industry’s first true 50G platform in 2020 with the Lightspan MF platform.
  • Once the 50G PON industry matures, the step to 100G is straight forward.


In March, Türk Telekom and ZTE carried out their own 50G PON trial in Turkey, which clocked speeds in excess of 50 Gbps in the downstream over a single fibre. It was apparently done so in a way that was compatible with existing PON generations already deployed in Türk Telekom’s network.

Meanwhile In April, Australia’s NBN demoed Nokia 100G PON tech to reach 83 Gbps on its live full fibre access network, eclipsing the previous trial the October before which achieved symmetrical throughput of 21 Gbps and was a new speed record for PON in Australia at the time.
