Abstract :
An 11 Gbit/s optical transmission experiment, employing a 1540 nm distributed feedback (DFB) laser modulated with non-return-to-zero signal format and an ultrawideband PIN/HEMT receiver, is described. This is the highest data rate transmission experiment reported to date using a directly modulated DFB laser. A span of 81 km of dispersion shifted fibre was employed resulting in a record bit rate-distance product of 890 Gbit/s km, with no observable penalty due to insertion of the fibre.
