Nokia and Türk Telekom successfully test 25G PON technology in Turkey

  • Turk Telekom is accelerating build out of Turkey’s leading high capacity network
  • First 25G PON trial in the country achieves 10 times higher bandwidth than is possible with existing GPON networks

30 November 2021

Espoo, Finland – Nokia and Türk Telekom have completed the first successful 25G PON trial in Turkey making it the fastest fiber network in the country. The laboratory trial took place in Türk Telekom Ankara Innovation Center and achieved downstream speeds of 20Gbps over a single wavelength.

Türk Telekom is exploring how to deliver superfast services to support smart city, office and home services.

Yusuf Kıraç CTO of Türk Telekom, said “Our goal is to provide better service quality to our consumer and corporate customers with faster and higher capacity technologies. The 25G PON solution we tested with Nokia achieves approximately 10 times higher bandwidth than is possible with existing GPON networks. Our trials demonstrated 20 Gbps for downstream and 9.1 Gbps for upstream which will enable us to support better quality for upcoming services such as 16K TV, 3D 360 degree videos and augmented & virtual reality experiences.”

Özgür Erzincan, General Manager of Nokia Turkey, said: “Global investments in fiber underline the importance of competitive advantage brought by high-speed networks. Nokia is the leader in 10Gb/s symmetrical PON and is the only manufacturer to offer a seamless transition to 25G speeds. We are happy to support Türk Telekom in deploying all three-generations of PON technology powered by Nokia's Quillion chipset simultaneously, enabling Turkey's first 25G PON network, and providing high-speed broadband to customers in Turkey's largest fiber (FTTH) network.”

Notes to editors

Nokia’s 25G PON solution utilizes the world’s first implementation of 25G PON technology and includes Lightspan and ISAM access nodes, Quillion based Multi-PON line cards and fiber modems.

Dependent on the optics chosen, 25G PON supports symmetrical bitrates (25Gb/s in downstream and 25G in upstream) and asymmetrical bitrates (25/10).

Usually located in telecom central offices, Nokia’s high-capacity access nodes are deployed for massive scale fiber roll-outs. They connect thousands of users via optical fibre, 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.
