Using existing optical infrastructure to transmit up to 400Gbit/s highlights the scalability of our FSP 3000 and shows our customers how much potential lies in their deployed networks.
The 400Gbit/s trial made use of the City of Cape Town’s existing WDM infrastructure, which stretches over more than 100km and covers the whole metropolitan area. The meshed network is built on the ADVA FSP 3000, a modular optical networking platform designed for scalability and bandwidth optimization. To achieve the phenomenally high channel capacity, the demonstrators created a two-wavelength super-channel. Data rates were then switched between 200, 300 and 400Gbit/s to show how capacity can be automatically adjusted according to the network’s shifting traffic and transmission quality requirements. Successfully transmitting a 300Gbit/s channel at just DP-8QAM is a significant milestone. This modulation format can handle lower signal-to-noise ratios for increased reliability, yet optimized fiber utilization.
“Using existing optical infrastructure to transmit up to 400Gbit/s highlights the scalability of our FSP 3000 and shows our customers how much potential lies in their deployed networks,” commented Günter Landers, sales director Africa, ADVA Optical Networking. “This trial demonstrates that backbone networks can be made to work even more efficiently so that future bandwidth demand can be met without the need for significant investment. The City of Cape Town is one of the leading municipalities in the country when it comes to providing its residents with state-of-the-art connectivity. It’s been great to work with them on a demo like this. We’ve proved that they already possess the infrastructure to do so much more. Their not-for-profit network will soon be able to give an even bigger boost to local businesses and enhance the life chances of more people.”
