Nokia and Megacable achieve 1.1Tbps Latin American optical transmission speed record


Nokia and Megacable announced that together they have achieved a Latin American speed record in long-distance optical transmission, having reached 1.1Tbps (Terabits per second) in a single-carrier wavelength transmission over a long-distance fiber network.

The trial was carried over one of Megacable’ s existing long-distance routes with challenging fiber conditions and maintained all actual required network margins to replicate a real-world deployment scenario. The milestone was achieved over 390km, with 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.

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.

Nokia’s PSE-6s is the industry’s most advanced digital coherent optics (DCO) technology, powering the latest generation of high-performance, high-capacity Nokia transponders, packet optical switches and disaggregated compact modular and subsea terminal platforms. The Nokia PSE-6s is the first platform that can support up to 1.2Tb/s in metro applications, and 800Gbps transmission over long-haul distances.

Having a next-generation optical transport network allows cutting-edge operators like Megacable to provide the high-speed, low-latency, high-quality ultra-broadband connectivity that is essential for business customers and is also necessary to support accelerated growth in residential users. Additionally, Megacable will benefit from lower energy consumption in the network and a lower operating cost per bit. It is expected that new 5nm PSE-6s will provide 45% less power consumption.
