Unrepeatered 80 Gbit/s RZ single channel transmission over 160 km of standard fibre at 1.55 mu m with large wavelength tolerance

Unrepeatered 80 Gbit/s RZ single channel transmission over 160 km of standard singlemode fibre at 1.55 mu m involving the use of passive compensation of the dispersion and dispersion-slope is reported. Error-free transmission (BER-10-9) with a receiver sensitivity of -22 dBm and a wavelength tolerance of 10 nm has been achieved.
