K. Yonenaga et al., EXPANSION OF TOLERABLE DISPERSION RANGE IN A 40GBIT S OPTICAL-TRANSMISSION SYSTEM USING AN OPTICAL DUOBINARY SIGNAL/, Electronics Letters, 34(4), 1998, pp. 385-386
The authors demonstrate the high dispersion tolerance of a 40 Gbit/s o
ptical duobinary signal. The tolerable dispersion range of the signal
was 175 ps/nm. This dispersion range is more than twice that obtained
using a binary non-return-to-zero intensity-modulated signal.
