Ciena powers trial of 300 Gbps transmission via coherent optical modulation

Ciena's WaveLogic 3 Extreme chipset was a key component of a successful trial to transmit 300 Gbps capacity using coherent optical modulation. The trial results were announced at this week's TNC16 Networking Conference.

Canadian advanced networking nonprofit Canarie and the StarLight Consortium conducted the trial using Ciena's open-interface, programmable system.

"The 150 Gb/s per wavelength 8QAM (quadrature amplitude modulation) trial was conducted on a live research network that connects Ciena's labs in Ottawa with StarLight's Chicago-based R&E communication services exchange facility, at a distance of more than 1,440 km," according to a Ciena release. The company said that 8QAM offers more flexibility in applications that can be enabled by its Waveserver stackable system, and it can provide high-capacity DCI, which it said it "instrumental" in connecting an increasingly app-centric, on-demand society.

"Traffic on our network continues to surge as we enable Canadian researchers, educators and innovators to leverage advanced digital tools and massive data resources," said Mark Wolff, CTO at Canarie, in a statement. "This trial demonstrated that Ciena's Waveserver is capable of enabling us to scale our network in order to help keep Canada at the forefront of digital research and innovation." Release
