Abstract:
A wavelength-division-multiplexing (WDM) system including:a first multiplexer, operatively interconnecting a plurality of digital information channels onto a transmission path;a transmission path including an optical fiber span whose length (L) exceeds 10 kilometers and whose zero dispersion wavelength (.lambda..sub.0) is about 1310 nm,CHARACTERIZED IN THATthe optical fiber has a loss at 1385 nm, which is less than its loss at 1310 nm, and a chromatic dispersion of between 1.5 and 8.0 ps/nm-km in the 1.4 .mu.m wavelength region; andwherein the first multiplexer provides at least three channels of WDM signals in the 1.4 .mu.m wavelength region onto the transmission path.
