NDFIS Response to BIS Capital Consultation

Professor Alwyn Seeds, Director of NDFIS, with optical networking equipment at UCL

 

The National Dark Fibre Infrastructure Service (NDFIS) is an Engineering and Physical Sciences Research Council (EPSRC) Mid-Range Facility, established in 2014 to enable researchers to develop the underpinning communications technologies for the future internet. EPSRC has provided £2.5 Million to fund the project. Following a competitive tendering process, the 5 year contract for NDFIS has been awarded to UCL as prime contractor for a consortium comprising the Universities of Bristol, Cambridge and Southampton. NDFIS will provide access to a dedicated dark fibre network connecting these universities, with onward connection to European and Worldwide research networks via telecommunications facilities in London. The network will be engineered with equipment that can be configured remotely and dynamically, and will be a pioneering example of a Software Defined Network (SDN). The fibre paths linking the Universities, comprising some 800 km of single mode fibre, together with control and monitoring systems, will be provided to NDFIS by Janet, part of the JISC group, funded by BIS through its e-Infrastructure programme. Researchers in the UK will be able to access the new network, to be named Aurora2, both directly by placing equipment at consortium sites and remotely using the Janet Lightpath service.

Dark fibre is optical fibre that users can access at the optical data level rather than the electrical data level as in conventional communications networks. Access at the optical level enables users to experiment with novel communication techniques, such as high order optical modulation or quantum communication.  The new service builds on previous work carried out by the consortium using a fixed path dark fibre network, Janet Aurora. The new network will offer programmable transmission parameters, dynamic reconfiguration into multiple sub-networks and the ability to handle multiple transmission formats simultaneously.

As well as supporting research on the future core optical network, which underpins the internet, NDFIS will also enable research with experimental metro networks, such as the Gigabit Bristol network. NDFIS will also support research on wireless backhaul networks for future Wireless Systems such as 5G.

NDFIS provides a key resource to researchers developing the future wireless and optical communications systems that will underpin the future internet.

Although, it is possible for researchers throughout the UK to send data and conduct research on the NDFIS Aurora2 network the geographical reach of the dark fibres forming the physical layer of the network is currently limited to the southern part of the UK.  We therefore propose that the reach of the Aurora2 network be extended by adding fibre routes to expand the geographical coverage to include further major centres of communications and networking research, through a northwards extension of the network, including for example Birmingham, Manchester, Lancaster, Strathclyde, Edinburgh and Northern Ireland. The cost of this enhancement would be £5m to £15m, depending on geographical extent.

Creating a Nationwide Dark Fibre Research Network would enable large scale experimentation to study flexible and reconfigurable networks offering unprecedented capacity. This will enable UK researchers to remain at the forefront of technology research for the future internet and its applications.

UK Photonics and UK electronics are large industries with annual revenues of £10 billion and £29 billion respectively. We will be working with leading UK companies to transfer technologies developed with the aid of NDFIS into new products and services. The benefits to the UK economy will be correspondingly large.
