NTT tunes up Ciena's 800G for data center interconnect in Japan

Thanks to working with Ciena, NTT Communications is laying claim to being the first telecoms provider in Japan to deploy 800G in its network.

NTT will deploy a single-wave 800G line speed solution for data center interconnect (DCI). The increased capacity will enable NTT to accommodate the growth of 5G services and applications, gaming and cloud services.  After postponing the summer Olympic Games this year, Japan is set to host the Tokyo Olympic Games next year.

NTT will be using Ciena’s WaveLogic 5 Extreme optical platform to increase the capacity and lower power requirements for its high bandwidth applications. Using the wavelength multiplexing technology, NTT Com’s upgraded network can support capacity up to 33.6Tbps between data centers in metro areas. Ciena's 800G technology can also scale up as needed.

While Ciena and Infinera have been battling each other to win 800G contracts, Ciena said it's currently the only company that's supplying 800G across live networks. This past summer, Verizon announced it had worked with Infinera to successfully test 800G on a single wavelength over 400 miles on its long-haul network between Dallas and Atlanta.

In May, Deutsche Telekom Global Carrier laid claim to the first European 800G transmission by partnering with Ciena.

Earlier this year, Verizon completed a test that pushed 800 Gbps of data across a single fiber wavelength by working with Ciena and Juniper networks. Verizon's 800G trial on its live fiber network was notable because it showed equipment interoperability from two different vendors. The trial proved the capability to quadruple the typical capacity that's normally carried on a wavelength.

Earlier this year, Ciena joined the Innovative Optical and Wireless Network Global Forum (IOWN GF), which was co-founded by NTT, Intel Corporation and Sony last year to define a next generation communications infrastructure.
