The demand for bandwidth in our telecommunication networks worldwide has been growing continuously by 50-100% per year for more than a decade, regardless of any economic crises. In recent years a number of new applications such as online gaming, cloud computing, high-definition video streaming, YouTube, Twitter, Flickr, etc. have kept demand growing and this trend is not likely to end. In order to cope with this increasing demand research and innovation in all parts of the telecommunication network are needed.
In the core part of the network, the current challenge is to increase the transported data capacity per wavelength channel to over 100 Gbit/s (Beyond 100G). But at the same time, the cost, power consumption and footprint per transported bit needs to decrease. Different technologies can be employed to achieve this task. The Submarine & Core Systems Group is a partner for research & development in all these fields.
