We report an experimental comparison between broadband fibre Bragg gratings (FBGs) and conventional dispersion compensating fibre (DCF) for a 40 x 10Gb/s DWDM system over 525km. A performance-optimised configuration using FBG compensators is presented.
We have investigated a new technique for the enhancement of a wavelength conversion system based on nearly degenerate four wave mixing in a InGaAsP DFB semiconductor laser amplifier. We report enhanced wavelength conversion over 20 nm from 1.55 /spl mu/m to 1.53 /spl mu/m using feedforward photomixing from two independent source lasers to directly modulate(More)
We report an experimental characterisation examining the impact of differing 50Hz neighbouring modulation formats and bit rates on the performance of 43Gb/s P-DPSK over 1300km of SSMF and LEAF<sup>TM</sup> fibre types. Performance is shown to be robust for hybrid P-DPSK and OOK systems.
