1.28 Tbit/s–70 km OTDM transmission usingthird- andfourth-order simultaneous dispersion compensationwith a phase modulator

Abstract
A single wavelength channel, optical time division multiplexed and polarisation multiplexed 1.28 Tbit/s signal has been successfully transmitted over 70 km. Third- and fourth-order simultaneous dispersion compensation was used with a 10 GHz synchronous phase modulator. The input pulsewidth was 380 fs, and the transmitted pulse width was 400 fs. All 128 channels demultiplexed to 10 Gbit/s had a bit error rate of less than 1 × 10-9.
