Nokia and TIM achieve 550Gbps on backbone network

30 May 2019

Nokia and Telecom Italia (TIM) say they have broken the European record for long-distance data transmission speeds over a backbone network. The firms say they achieved a wavelength speed of 550Gbps on TIM’s 350km network between Rome and Florence using the new Nokia Photonic Service Engine 3 (Nokia PSE-3) solution. In addition to this milestone, TIM and Nokia also say they reached a transmission rate of 400Gbps over a distance of 900km between Rome and Milan, and 300Gbps over a 1,750km route.

TIM’s DWDM backbone network currently has a capacity of 100Gbps over distances of up to 1,800km, and 200Gbps up to 800km. The network includes 16,000km of fibre and connects 65 PoPs nationwide.

Elisabetta Romano, Chief Technology & Innovation Officer at TIM, said: ’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.’

Earlier this month, rival Italian ISP Fastweb carried out a successful demonstration of 500Gbps single-wavelength service connectivity on its live network using technology supplied by Infinera. The live trial was conducted on Fastweb’s 180km fibre backbone link between Milan and Turin.
