Ciena announced that Japanese service provider QTnet will deploy its 6500 packet-optical platform to support growing demand with higher levels of network capacity, flexibility and resiliency.

QTnet offers fiber optic cable, internet, video and broadband telecommunications services to hundreds of thousands of households and enterprises and local governments in Kyushu, Japan’s third largest island. Ciena’s 6500 platform – powered by the company’s WaveLogic Ai programmable coherent optics – will enable QTnet to increase capacity up to 400 Gbps per wavelength across its upgraded flexible grid network.

The solution will also help improve QTnet’s competitive advantage by enabling the operator to offer higher speed connectivity services, gain more fiber capacity, and reduce power and footprint, with fewer wavelengths to manage, Ciena says.

Additionally, the 6500’s flexible grid with a colorless, directionless, contentionless (CDC) photonic layer and Layer 0 control plane for self-healing capabilities will future-proof the network for new technologies, Ciena adds. It will also provide the highest resiliency against potential network/fiber failures and will serve to protect QTnet’s customer traffic from natural disasters, such as typhoons, torrential storms and earthquakes which impact the island of Kyushu.

“For our network upgrade, we needed a high capacity solution that can provide higher reliability and that can also withstand large-scale natural disasters,” said Sadao Mouri, director and senior managing executive officer at QTnet.
