O. Leclerc et al., Demonstration of high robustness to SNR impairment in 20Gbit/s long-haul transmission using 1.5 mu m saturable absorber, ELECTR LETT, 36(23), 2000, pp. 1944-1946
Improved robustness to signal-to-noise ratio impairment is shown for the fi
rst time at 20Gbit/s in an RZ transmission loop using a 1.5 mum heavy-ion-i
rradiated quantum well saturable absorber. Error-free transmission is achie
ved over 7800km.
