Deliverables Short pulse generation Summary: Short pulse generation opens for optical multiplexing up to 40, 80 and 160 Gbit/s enabling the operation of all-optical trunk lines at such bit rates using lower bit rate digital electronics. Optical time division multiplexer Summary: All optical demultiplexing from 40, 80 and 160 Gbit/s have been demonstrated enabling the operation of all-optical trunk lines at such bit rates. Exploitable results HIGHWAY: photonic technologies for ultra high speed information highways HIGHWAY addresses promising ultra-high speed optoelectronic components and subsystem technologies for photonic 40 Gbit/s time division multiplexed (TDM) transport systems. Advanced TDM system laboratory demonstrators are to be realised and tested over field-installed fibre. The field experiments will demonstrate that the 40 Gbit/s TDM system technologies developed offer promising options for a field deployment of high capacity information highways in future trans-European telecommunication networks. HIGHWAY has so far achieved substantial progress with respect to component/ subsystem development, subsystem/system functional tests, 40 Gbit/s transmission tests and the definition and preparation of field test infrastructures. A large number of advanced components/subsystems with attractive features have been realised (some packaged), demonstrated or designed including 10/40 GHz optical return to zero (RZ) sources, modulators, 10/20 GHz laser based or, semiconductor optical amplifier (SOA)-based clock recovery, 40/10 Gbit/s optical demux, 10/40 Gbit/s ADM, 10/20 Gbit/s optical preamp receiver, 40 Gbit/s electronic circuit design/layout, and SOA-based 40 Gbit/s mid-span-spectral-inversion (MSSI). All basic system functionalities for 40 Gbit/s TDM transport have been demonstrated using the above-mentioned elements. 40 Gbit/s transmission experiments have been performed successfully, including clock extraction. 40 Gbit/s has been transmitted over up to 400 km of standard (non-dispersion-shifted) single-mode fibre (SSMF) using MSSI for dispersion accommodation. These laboratory experiments have confirmed the viability of the proposed options. Theoretical models for the evaluation of basic system limitations and of dispersion accommodation at 40 Gbit/s have been developed and used for the analysis of long-haul transmission, in laboratory experiments. This work provides a solid theoretical background for the reliable prediction of system performance and final system specification. The fibre link infrastructures for the system field tests have been defined and specified by the respective telecommunication operators. Searching for OpenAIRE data...
