Two channel wavelength division multiplexing (WDM) over a 908km path w
ith seven in-line erbium doped fibre amplifiers (EDFAs) is reported. A
t the 10Gbit/s transmission level the line exhibited a good performanc
e margin and significant robustness to simulated faults. To the author
s' knowledge, this is the longest amplifier spacing reported in a syst
em of this length at this line rate.
