Effective utilization of optical transponders in WDM mesh networks

Effective utilization of optical transponders in WDM mesh networks We consider a multi-degree optical node configuration, which can provide multiple fiber links to the other nodes in wavelength-division-multiplexing (WDM) mesh networks.

Abstract

We consider a multi-degree optical node configuration, which can provide multiple fiber links to the other nodes in wavelength-division-multiplexing (WDM) mesh networks. In the node, optical transponders are utilized for the wavelength channels sources and 3R-wavelength converters. It is shown that blocking originated from both the limited signal impairment threshold (SIT) problem and wavelength contentions can be resolved by the optical transponders. Moreover, the number of optical transponders per fiber link can be reduced down to half of the number of wavelength channels without degrading the network performance.
