Abstract
Wavelength-division-multiplexing (WDM) transmission in lightwave systems allows increasing fiber capacity by the simultaneous transmission of multiple channels through a single optical fiber. An example is the recent demonstration of 340 Gb/s transmission over 150 km by wavelength-division multiplexing seventeen 20 Gb/s channels [1]. WDM also enables better network topologies, eases capacity growth, reduces the demands on high-speed electronics, and improves system reliability and robustness.
