GMPLS-based transparent optical networks suffer from accumulation of physical layer impairments (PLIs) and wavelength continuity constraint along the transparent optical path. To increase optical reach, resource utilization, and average call acceptance ratio (and hence the revenues), network operators resort to translucent optical networks. In these networks a limited number of regenerators are placed...
In conventional optical data transmission schemes, electrical filters and/or optical filters are used to improve the quality of system performance. In this paper, improved design of dense wavelength division multiplexing (DWDM) optical systems is achieved by using a selective electrical filter assignment method. The methodology objective is to optimize system design and mitigate the effects of fiber...
