We demonstrate 100 GHz-spaced 40/spl times/43 Gb/s WDM transmission over 2540 km of SMF fibre in a terrestrial configuration, with combined erbium and Raman amplification and a standard NRZ format. All channels perform better than the enhanced FEC limit.Show More
Error-free unrepeated C+L transmission of 320 25 GHz spaced channels at 10.66 Gbit/s over 310 km is demonstrated. A low noise distributed Raman amplification over 72.4 nm optical bandwidth is implementedShow More
A fully broadcasting 128/spl times/128 cross-connect with an all-optical switching fabric has been designed and a managed, rack-mounted prototype based on commercially available technologies has been developed for testing. System architecture and experimental results are reported, and 512/spl times/512 feasibility is demonstrated.Show More
