Updates from Ciena

500G transpacific. Yep, we did that!
The news from SubOptic? Let’s start with our successful single-wavelength 500G field trial over a 9,000km transpacific cable. Ciena’s Brian Lavallee explains more about this milestone as well as other highlights from this important technical conference.
By Brian Lavallée – SubOptic 2019 has recently come to a close, and as the locals say, “laissez les bon temps rouler”, or let the good times roll – and they did.

We shared the news of a successful single-wavelength 500G field trial over a 9,000km transpacific cable, which was completed just before the event. Of course, this means we can also do 500G single-wavelength transmission across much shorter transatlantic distances too. The transpacific field trial leveraged our very latest WaveLogic 5 Extreme coherent optical technology, which truly takes our pioneering submarine networking solution,

GeoMesh Extreme, to the extreme. In just under a decade, we’ve leaped from 10G to 500G transpacific – a truly impressive feat.

How did we achieve such performance?

By leveraging advanced Digital Signal Processing (DSP) capabilities, 95Gbaud operation, Probabilistic Constellation Shaping (PCS), throughput-optimized FEC, and nonlinear mitigation techniques. more>
