Mexico's Megacable transmitted 1.1 Tbps in a single-carrier wavelength over 390 km on one of its existing long-distance routes.
For the trial, Nokia deployed a next-generation optical transport solution, based on its sixth-generation super-coherent PSE-6s technology over its existing 1830 PSS optical transport platform, running live traffic without any impact to the network. The transmission passed through several intermediate ROADMs and no Raman amplifications. A previous test, run under similar conditions, demonstrated 900 Gbps in a single-carrier transmission over 600km. On both tests, the channel speeds were achieved without regeneration.
The tests are part of the actions that Megacable is taking to rapidly scale its network capacity and increase its long-distance data transmission speeds from 9.6Tb to 28.8Tb in a first phase using Nokia’s Photonic Service Engine-Vs (PSE-Vs) coherent optics, and up to 38.4Tb with the new PSE-6s in a second test phase that will interconnect all its data centers nationwide.
Miguel Sol, Chief Technology Officer at Megacable, said: “We selected Nokia for this trial to prove our network evolution, since our first deployment with Nokia was 9.6 Tbps of total capacity. As part of our technology innovation and evolution program, we agreed with Nokia to set and select the transport routes to perform the trial of their new PSE-6s chipset. It will allow us to increase optical spectrum efficiency, enabling capacities up to 38.4Tbps, as well as cost and power consumption efficiencies over our Optical Long Haul fiber network. Those are the key aspects that we evaluate to cover the requirements of all markets to which Megacable provides connectivity, especially for Fiber High-speed connectivity, dedicated Enterprise links and Carriers-to-Carrier services. The new PSE-6s coherent optics, will allow Megacable to do a fast deployment of ultra-high-capacity wavelengths on the most high-demand routes of our network, and deliver the best connectivity for our customers in Mexico.”
