Sb. Alleston et al., 1000 km transmission of 40 Gbit s single channel RZ data over dispersion managed standard (non-dispersion shifted) fibre, ELECTR LETT, 35(10), 1999, pp. 823-824
Error-free transmission of a single polarisation optical time division mult
iplexed 40Gbit/s dispersion managed pulse data stream over 1009km has been
achieved in dispersion-compensated standard (non-dispersion shifted) fibre.
This distance is twice the previous record at this data rate.
