Facing competitive pressures and rapidly accelerating user demand for interactive services, cable operators need to upgrade their network architectures. These upgrade requirements are pushing optical fiber deeper into the network. But simply replacing existing transmission lines with fiber is no longer the most cost-effective way to handle increasing bandwidth requirements. Operators are now taking advantage of advances in optical filtering that significantly increase the number of signals (or wavelengths) that can be carried on a single fiber, a process known as dDense wavelength-division multiplexing (DWDM).
