D. Mathoorasing et al., 109KM TRANSMISSION EXPERIMENT AT 20GBIT S WITH DIRECTLY MODULATED DFBV-ON-U GROOVE (VUG) LASER/, Electronics Letters, 30(6), 1994, pp. 507-508
Transmission over 109km of dispersion shifted fibre is successfully ac
complished without penalty and errors at 20Gbit/s rate using a 10 well
1.5mum high-speed MQW DFB laser biased at 24mA DC with a low modulati
on voltage swing of 1.5V peak to peak.
