March the 13th, 2022 - Hrvatski Telekom/Croatian Telecom (HT) and Nokia were among the first in the entire world to test advanced 25G PON optical technology in the HT Rijeka lab.

As Poslovni Dnevnik writes, this is the latest generation of optical network, which increases the speed of download and transmission to unprecedented levels, and with this test, the Rijeka lab measured a speed of 20 gigabits per second.

25G PON technology is otherwise ten times faster than GPON technology, which was enabled by HT for the first time with gigabit broadband access back in 2007, then again but two and a half times faster than XGS-PON technology which was applicable within the HT network from 2021.

The equipment currently used by Hrvatski Telekom is ready for 25G PON, which means that it isn't necessary to make any further adjustments to the main systems in order to realise its commercial availability.

The biggest advantages of 25G PON optics are large capacities, cost optimisation, a generally wider application and a simple introduction into the existing HT optical network, and its application will accelerate the introduction and development of advanced high-performance solutions such as big data, artificial intelligence (AI) and machine learning.

"Ten years ago, a piece of technology was launched that enabled the transition to HDTV without which many of us wouldn't be able to imagine everyday life now, and today the 25G PON optical network is making history at speeds 200 times faster than that. By testing 25G PON optics and being among the first in the world to do so at the Rijeka lab, Hrvatski Telekom is highlighting its commitment to establishing and maintaining the best user experience through monitoring and introducing some of the world's most modern technological trends,'' said Ivan Uremovic, the director of Strategy and Planning of Access Networks.

Hrvatski Telekom is otherwise one of the first companies from the Deutsche Telekom Group to test out Nokia's broadband 25G PON optics.

Manfred Egger, head of Fixed Access Network Development for Deutsche Telekom and Central Europe at Nokia, said:

“25G PON works flawlessly on the same hardware with existing GPON and XGS-PON broadband technologies. We're very proud to have successfully completed this important test, which confirms the ease with which communication service providers can expand their scope and capacity of broadband access.''

Back in 2021, Hrvatski Telekom increased its fixed network with a record introduction of optics for a new 100,000 households and companies, and the total FTTH coverage increased by 30 percent compared to last year. In that same year, HT was also awarded Umlaut's "Best in Test" award for the best fixed network.

ZAGREB, 10 March 2022 - Hrvatski Telekom (HT) and Nokia on Thursday tested in Rijeka Nokia's 25G PON broadband optical network, a new generation of optical networks that significantly enhances the speed of data transfer, HT said.

The first national testing of Nokia's network was performed in HT's Rijeka laboratory, as part of which high speeds were achieved, of 20 gigabits per second.

"25G PON technology is ten times faster than GPON technology, whereby HT enabled a gigabit broadband connection for the first time in 2007. It is also two and a half times faster than XGS-PON technology that has been in use in HT's network since 2021," the company said, adding that HT's equipment was ready for 25G PON and that adjustments of the main systems to enable its commercial availability were not necessary.

The commercial use of the technology will be possible once user services for the network are developed.

HT says the biggest advantage of the 25G PON optical network is its high capacity, cost optimization, broader use, and simple introduction in HT's existing optical network.

HT expects the new optical network to facilitate the development and introduction of advanced, high-performance solutions such as big data, artificial intelligence, and machine learning, 5G transport via PON, and ultra-high capacity wholesale services.
