Paper Abstract

DWDM networks consist of many densely packed wavelength channels propagating independently (and even bi- directionally) within the physical fibers making up a given system. The `virtual fibers' within a DWDM transport network, aside from providing higher bandwidth capability, are able to expand overall network flexibility as well as improve reliability. Bandwidth increase is satisfied by adding wavelength channels via increasing the density of channels and/or by expanding the spectral region for incorporating additional channels. The increased flexibility addresses complex and continuously varying topologies and the frequent need to flexibly add/drop channels and re- provision channels. Further, the incorporation of non- intrusive monitoring of all optical wavelengths s improves network reliability by enabling element control, improved network management, and predictive network failure capability.
