Telecom Italia (TIM) and Nokia have claimed a record wavelength speed of 550 Gbps, the highest ever in Europe for data transmission over a long-distance backbone network and triple the bandwidth of the Italian operator’s current network. The high-speed trial covered the 350km length of TIM’s operational network between Rome and Florence using the new Nokia Photonic Service Engine 3. The partners also reached a transmission rate of 400 Gbps over 900 kilometres between Rome and Milan, and 300 Gbps over 1,750 kilometres.

Nokia described PSE-3 as the first coherent DSP to implement a sophisticated signal processing algorithm known as Probabilistic Constellation Shaping (PCS), designed to maximise data transport capacity over any distance. TIM’s backbone is a Wavelength Division Multiplexing (WDM) network based on the latest generation of Nokia’s 1830 Photonic Service Switch. It covers over 16,000km of fibre and connects to 65 national Points of Presence, carrying over 9,000 petabytes of data traffic in the last year alone.

We are proud of this European record which confirms TIM’s technological leadership, the high quality of our network, our commitment to develop innovative solutions in order to guarantee the best experience to our customers. Today’s result, which triples transmission speed compared to the current one, confirms that TIM’s network is the most advanced infrastructure capable of offering new digital services and platforms, also with a view to developing 5G,” said Elisabetta Romano, Chief Technology & Innovation Officer at TIM.
