TIM, Nokia send 600G over 1008-km long-haul fiber network
Nokia says it has completed a successful 600-Gbps transmission trial with Italy’s TIM. The trial included the transmission of 600 Gbps over a 1008-km link within TIM’s terrestrial fiber backbone network.
The trial used fielded colorless, directionless, and directionless flexible-grid ROADMs from Nokia (specifically, 1830 PSI-M compact modular disaggregated transport systems) that TIM is using for its backbone infrastructure. The ROADMs were equipped with the technology vendor’s PSE-Vs super coherent optics. The 600G transmission leverage 100-GHz channels and produced a spectral efficiency of 6 bits/sec/Hz, which Nokia asserted was a record.
The route featured mixed SMF/LEAF fiber on a link that connected Torino to Rome; the link comprised 18 fiber spans and ran through five ROADM nodes. As part of the trial, the two companies also transmitted 400 Gbps over a 2140-km link from Torino to Catania, Sicily. That link contained 37 fiber spans and 12 ROADMs nodes.
The trial established TIM’s ability to support 400 Gigabit Ethernet services when using the PSE-Vs coherent technology. “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.”
