摘要： Techniques and a control architecture (apparatus and logic) are provided for an adaptive hybrid DWDM-aware computation scheme. The architecture is one that is a hybrid of a centralized control scheme and a distributed control scheme that performs adaptive physical impairment computations for an optical network. A central control server is connected to multiple client control devices each of which resides in a node in a dense wavelength division multiplexed (DWDM) optical network, wherein each client control device is part of an optical control plane associated with the optical network. The control server obtains data for path route analysis from the client control devices. The control server then determines optical feasibility of at least one path route from a source node to a destination node from optical parametric information based on the data obtained from multiple client control devices and without real-time communication between the central control server and the multiple client control devices while performing the optical feasibility computations.

摘要： A reconfigurable WDM add/drop multiplexer and its method of operation at an add/drop node on an optical fiber carrying a plurality of WDM signals is described. The WDM add/drop multiplexer has a coupler and a demultiplexer element dropping WDM signals from the optical fiber to a plurality of drop terminals, and a wavelength-selective switch adding WDM signals from a plurality of add terminals onto the optical fiber. The coupler splits the WDM signals received from the optical fiber and passes the split WDM signals to the first and second output terminals. The demultiplexer element separates the split WDM signals at the plurality of drop terminals. The wavelength-selective switch, which has an input terminal for connection to the second coupler output terminal and an output terminal for connection to the optical fiber, selectively adds WDM signals on the plurality of add terminals to the optical fiber responsive to control signals.

摘要： A mesh optical network node has switch cards which carry active components, such as wavelength routers to switch the paths of optical signals through the node and a fiber organizer handles the numerous optical fiber interconnections among the switch cards. The fiber organizer has no active components and can include optical paths to verify not only that a switch card connection to the fiber organizer has been made but that the connection is properly made.
