M. Jinno et al., FIRST DEMONSTRATION OF 1580 NM WAVELENGTH BAND WDM TRANSMISSION FOR DOUBLING USABLE BANDWIDTH AND SUPPRESSING FWM IN DSF, Electronics Letters, 33(10), 1997, pp. 882-883
The author; demonstrate WDM transmission in the unexplored 1580nm band
, for the first time, using newly developed gain-shifted EDFAs. By usi
ng the 1580nm band, equally-spaced eight 10Gbit/s WDM channel, repeate
rless transmission over 160km dispersion-shifted fibre is achieved wit
hout any four-wave mixing degradation.
