Hs. Chung et al., 640/Gbit/s (32 x 20 Gbit/s) WDM transmission with 0.4 (bit/s)/Hz spectral efficiency using short-period dispersion-managed fibre, ELECTR LETT, 37(10), 2001, pp. 618-620
640Gbit/s (32 channel x 20Gbit/s) WDM transmission with 0.4(bit/s)/Hz spect
ral efficiency is demonstrated using short-period dispersion-managed fibre
(Perfect Cable (TM)). The average Q-factor was measured to be better than 1
8dB after transmission over 280km.
