Nokia achieves 600G transmission milestone over 1008km long-haul network in Italy

0 20

Nokia today announced that they have successfully completed a network trial with TIM using the Nokia PSE-Vs fifth generation super coherent optics. The trial demonstrated 600G transmission over a 1008km live link in TIM’s terrestrial backbone network in Italy. 

“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.”

James Watt, Head of Optical Networks Division, Nokia

This trial sets new milestones in spectral efficiency over a live, real-world network. It also enables TIM to further increase its optical network capacity and support 400 Gigabit Ethernet (400GE) services across its long-haul network.    

The trial was Performed on a long-haul route connecting TIM’s live network of mixed SMF/LEAF fiber spanning the breadth of Italy, using Nokia’s 1830 PSI-M compact modular disaggregated transport system. 

This trial leverages TIM’s existing long-haul network based on Nokia’s CDC-F ROADM architecture and demonstrates the ability to achieve milestone transmission speeds of 600G per wavelength using PSE-Vs super coherent optics from Nokia. 

TIM and Nokia demonstrated error-free performance at 600Gb/s over a 1008km link from Torino to Rome, consisting of 18 fiber spans and through five ROADMs nodes, and 400Gb/s over a 2140km link from Torino to Catania, Sicily, consisting of 37 fiber spans and 12 ROADMs nodes.

“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”.

Alberto Maria Langellotti, Head of IP, Transport & SDN Engineering, TIM Italy

Operating with 100GHz WDM channels to maximize network capacity, this trial sets a milestone spectral efficiency record of 6.0bits/sec/Hz over TIM’s strategic long-haul routes.

The Nokia PSE-V is the industry’s most advanced family of digital coherent optics (DCO), powering the next generation of Nokia high-performance, high-capacity transponders, packet-optical switches, disaggregated compact modular and subsea terminal platforms. 

The PSE-V super coherent DSP (PSE-Vs) implements the industry’s only second generation probabilistic constellation shaping (PCS) with continuous baud rate adjustment, and supports higher wavelength capacities over longer distances,  including support for 400G over any distance,  over spectrally efficient 100GHz WDM channels while further reducing network costs and power consumption per bit.
