The OCEAN project aimed to develop cost-effective optical orthogonal frequency division multiplexing (OOFDM) systems for future access networks. The 39 month project comprised Bangor University (Coordinator, UK), Heinrich-Hertz-Institut (DE), Fujitsu Semiconductor Europe (FSE, UK), Fujitsu Labs (non-funded partner, JP) , VPI Photonics (DE), Finisar (IL) and TerOpta (UK) which joined the project following the withdrawal of FSE after the second year.
By making use of commercially-available, low-cost optical/electrical components, the project developed a number of world-first, real-time, end-to-end, adaptive OOFDM transceivers operating at signal bit rates of up to 30Gb/s for various cost-sensitive application scenarios. The transceivers offered unique features including, for example, on-line performance monitoring and optimization, digital signal processing (DSP)-based effective compensation of both linear and nonlinear component/system/network impairments, as well as excellent performance flexibility and adaptability to both channel spectral characteristics and data traffic conditions. In addition, the feasibility of utilising conventional 10G-class intensity modulators to achieve >100Gb/s/λ OOFDM transmissions has also been experimentally confirmed for short-reach applications. The OCEAN results indicated that the development of cost-effective, high-speed, flexible and intelligent OOFDM transceivers is practically feasible for the realisation of software-defined networking-enabled elastic optical networks satisfying highly dynamic end-users’ data traffic patterns.
