WDM networks in general depend on transmitters and receivers that are precisely tuned to predetermined fmed wavelengths. Robust WDM is an approach aimed at relaxing manujkcturing and operating wavelength tolerance requirements, which will lead to cost effective implementations. In this approach, connections are based on dynamically selected wavelengths as(More)
Many WDM architectures are based onJixed wavelength channels which require the lasers to be tuned to their channels accurately. Achieving this task is difJicult and costly especially in the distributed environments. Robust WDM is an approach that tolerates large laser wavelength variations, due to temperature drifts and manufacturing tolerances. A(More)
SUMMARY WDM networks depend on predetermined, fixed wavelength channels, requiring highly stable lasers and tunable filters. Robust WDM networks, based on dynamically selected wavelengths, relax manufacturing and operating wavelength tolerance requirements leading to low-cost implementations. A node dynamically selects a currently unused wavelength for(More)
