Ciena's WaveLogic Ai Improves QTnet's Network Flexibility, Capacity and Resiliency

QTnet selected Ciena to Support Network Expansion in Kyushu, Japan

Ciena's
(NYSE:CIEN) 6500 Packet-Optical Platform powered by WaveLogic Ai has
been chosen by QTnet,
a communications service provider in Kyushu, Japan to support growing
demand for telecommunications services. Through this deployment, QTnet
will achieve higher levels of network capacity, flexibility and
resiliency.

Key Facts:

• 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. Japan is prone to natural disasters, such as typhoons,
  torrential storms and earthquakes. Located southwest of the main
  island of Honshu, Kyushu also experienced earthquakes and torrential
  rain damage.
• Ciena's 6500
  Packet-Optical Platform powered by WaveLogic
  Ai programmable coherent optics will enable QTnet to increase
  capacity up to 400 Gb/s 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,
  all with fewer wavelengths to manage.
• 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. 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.

Executive Comments:

• "For our network upgrade, we needed a high capacity solution that can
  provide higher reliability and that can also withstand large-scale
  natural disasters. By selecting Ciena's WaveLogic Ai, we are convinced
  that we can give our customers high capacity, reliable and stable
  service. This upgrade supports QTnet's vision of "Delivering ‘New
  Lights' to open up New Generation from Kyushu", and allows us to
  continue delivering "impressive quality" to our customers' daily lives
  and businesses."
  - Sadao Mouri, Director & Senior
  Managing Executive Officer, QTnet
• "This deployment is yet another example of our continued success in
  the Asia-Pacific region. With an adaptive and resilient optical
  network powered by our WaveLogic Ai, QTnet can increase its network
  capacity and assess the demands being placed on its network in real
  time. With this additional network insight, QTnet will also be able to
  dynamically adjust capacity to meet customer demands."
  - Hiroyuki
  Kume, President, Ciena Communications Japan
