Project Abstract

At present, there is a large demand for green optical networks, viz. backbone optical networks with an increased optical fibre capacity and transmission distance at low operating cost and reduced power consumption. This is dictated by growing applications of e-commerce, e-banking and e-business, broadcasting media and medical applications. GRIFFON addresses the disruptive change in information and communication solutions towards drastic energy saving (green) technologies in the context of fast development and delivery of new technology, as well as cross-sectoral and multi-disciplinary staff training. GRIFFON offers increased communication capacity through coherent technique with advanced modulation formats and polarisation multiplexing of signals, increased distance and reduced power consumption by applying an ultra-long second cascade fibre Raman amplification with supressed polarisation impairments, viz. polarisation dependent gain (PDG) and polarisation mode dispersion (PMD). The project merges four complimentary fields of expertise brought by well-recognized participants: VPI – advanced modelling and design of fibre optic communications links; Aston – high-speed communication systems and Raman technologies; KTH – the development of high-speed transmitters, receivers and modulators for high-capacity fibre optic communications; and ACREO – digital signal processing techniques and algorithms for compensation of linear/nonlinear transmission impairments in coherent communication systems, to create synergy in development of innovative devices and products for new generation of optic fibre communication and secure communication systems. The proposed Academia-Industry Knowledge Transfer Programme will stimulate development of new photonic products, training the researchers through secondments, exchange of skills and recently emerged technologies and will assist to establish a long-term collaboration between the university groups and industry.

 

The GRIFFON overall scientific objective is to develop an a green optical network, viz. fibre optic coherent communication system with increased capacity, distance (over 300 km) and reduced power consumption based on an ultra-long 2nd cascade fibre Raman amplification with supressed polarisation impairments, viz. polarisation dependent gain (PDG) and polarisation mode dispersion (PMD), and digital signal processing to suppress linear (chromatic dispersion, phase noise, polarisation mode dispersion) and intra-channel nonlinear (Kerr nonlinearity) transmission impairment The GRIFFON overall objective of the Transfer of Knowledge (ToK) is to facilitate sharing of knowledge and culture between the participants through inter-sector and trans-national two-way secondments of research staff, networking activities, organisation of workshops and conferences.
