Nokia has completed a network trial with Telecom Italia (TIM), demonstrating 600G transmission over a 1008km live link in the latter’s terrestrial backbone network in Italy.

It is thought that the trial will enable TIM to further increase its optical network capacity and support 400GbE services across its long-haul network. It leveraged TIM’s existing long-haul network based on Nokia’s CDC-F ROADM architecture and demonstrated the ability to achieve the aforementioned transmission speeds using PSE-Vs super coherent optics from Nokia. Operating with 100GHz WDM channels to maximise network capacity, this trial also demonstrated 6.0bits/sec/Hz over TIM’s strategic long-haul routes.

It was performed on a long-haul route connecting TIM’s live network of mixed SMF/LEAF fibre spanning the breadth of Italy, using Nokia’s 1830 PSI-M compact modular disaggregated transport system. TIM and Nokia demonstrated error-free performance at 600Gb/s over a 1008km link from Torino to Rome, consisting of 18 fibre spans and through five ROADMs nodes, and 400Gb/s over a 2140km link from Torino to Catania, Sicily, consisting of 37 fibre spans and 12 ROADMs nodes.

Alberto Maria Langellotti, head of IP, transport and SDN engineering at TIM Italy, commented: ‘This live network field trial validates our plans to seamlessly scale network capacity everywhere over our existing long-haul network, using the latest generation of high-performance coherent optics. With this trial, we demonstrate a record spectral efficiency over our advanced network to ensure the best dissemination of new digital services.’

James Watt, head of optical networks division at Nokia, added: ‘We are delighted to work with TIM to support continued capacity evolution of its core long-haul network. With the introduction of the PSE-Vs super coherent capabilities, we enable scale made simple across our entire 1830 portfolio. Nokia is enabling spectrally-efficient network capacity over real-world long-haul networks while setting new milestones for capacity-reach performance.’
