25G PON technology trialled in Turkey

Provider Türk Telekom is accelerating the build out of its high-capacity network in Turkey. 

As part of this, the formerly state-owned firm has completed its first successful 25G PON trial in Turkey, which the company said achieves 10 times higher bandwidth than possible with existing GPON networks. 

The laboratory trial took place at the Türk Telekom Ankara Innovation Center and achieved downstream speeds of 20Gb/s over a single wavelength. Türk Telekon selected Nokia’s 25G PON solution, which includes Lightspan and ISAM access nodes, Quillion based Multi-PON line cards and fibre modems. The Turkish provider is exploring how to deliver superfast services to support smart city, office and home services. 

Yusuf Kıraç CTO of Türk Telekom explained: ‘Our goal is to provide better service quality to our consumer and corporate customers with faster and higher capacity technologies. Our trials demonstrated 20Gb/s for downstream and 9.1 Gb/s for upstream, which will enable us to support better quality for upcoming services such as 16K TV, 3D 360 degree videos and augmented and virtual reality experiences.’

Özgür Erzincan, general manager of Nokia Turkey, added: ‘Global investments in fibre underline the importance of competitive advantage brought by high-speed networks. 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 fibre (FTTH) network.’
