QTnet selected Ciena to Support Network Expansion in Kyushu, Japan

(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

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
    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.
