The remarkable success of the internet is unquestioned, touching all aspects of our daily lives and commerce. This success is fundamentally underpinned by the tremendous capacity of unseen underground and undersea optical fibre cables and the technologies associated with them. Indeed, the initial surge in web usage in the mid-1990s coincides with the commissioning of the first optically amplified transatlantic cable network, TAT12/13 allowing ready access to information otherwise inaccessible. In parallel with the consistent exponential increase (quadrupling every 4 years) in broadband access rates, optical transceivers used in the core of the communications network have typically grown in bandwidth at the same rate, excepting a small and temporary downturn associated with the introduction of coherent technologies. Today, just as broadband demands begin to outstrip the capabilities of the incumbent technology (twisted pair copper cables) requiring new technology (optical fibre) to be deployed, bandwidth demands in the core network are exceeding the capabilities of single carrier modulation.In this project we will develop low cost all optical techniques to continue to expand the bandwidth of the transceivers which power the internet. Our all optical solution has the potential to be compact, suiting applications both within data centres operated by the likes of Google, Facebook and Microsoft and within the core international networks. The solution will address important challenges at such high bandwidths, such as synchronisation, noise and digital signal processing. If successful EEMC2 will deliver a transponder with more than an order of magnitude more capacity than those commercially available, equivalent of a Gb broadband connection rather than 70 Mb.

互联网的巨大成功是毋庸置疑的，触及我们日常生活和商业的方方面面。这一成功从根本上得益于看不见的地下和海底光纤电缆及其相关技术的巨大容量。事实上，20世纪90年代中期网络使用的最初激增与第一个光学放大跨大西洋电缆网络TAT 12/13的投入使用相吻合，该网络允许随时访问否则无法访问的信息。在宽带接入速率持续呈指数级增长（每4年增长4倍）的同时，通信网络核心中使用的光收发器的带宽通常也以相同的速度增长，但与相干技术的引入相关的小规模和暂时的下滑除外。今天，正如宽带需求开始超过现有技术（双绞线铜缆）的能力，需要部署新技术（光纤）一样，核心网络的带宽需求也超过了单载波调制的能力。在这个项目中，我们将开发低成本的全光技术，以继续扩大为互联网提供动力的收发器的带宽。我们的全光解决方案具有紧凑的潜力，适合Google，Facebook和Microsoft等运营的数据中心以及核心国际网络中的应用。该解决方案将解决如此高带宽的重要挑战，例如同步、噪声和数字信号处理。如果成功的话，EEMC 2将提供一个比商业上可用的容量大一个数量级的转发器，相当于Gb宽带连接而不是70 Mb。
