Transmission of a 4 x 10Gbit/s optically time division multiplexed dat
a signal over an urepeatered link comprising 80km of standard non-disp
ersion shifted fibre is demonstrated. The 1300pns/nm dispersion of the
link is balanced using a length of dispersion compensating fibre loca
ted at the OTDM transmitter, and the signal is demultiplexed to 10Gbit
/s using a semiconductor optical amplifier.
