摘要： A method of configuring a rack-mountable chassis is provided. The method includes measuring a length and width of a card module slot of the chassis, a first opening width of a first rack for housing the chassis, and a second opening width of a second rack for housing the chassis, where the first opening width is greater than the second opening width. The method also includes verifying whether the first opening width is sufficiently wide to allow enough clearance between at least one side of the chassis and the first rack when the chassis is disposed in the first rack, to allow for the adequate cooling of housed components. If the first opening width is sufficiently wide, a dimension of at least one parameter related to the configuration of the chassis is determined so that the second opening width is a multiple of a total chassis width of the chassis. A chassis configured according to the method is provided.

摘要： In today's reconfϊgurable optical add/drop multiplexer (ROADM) based optical node, ROADMs multiplex (and demultiplex) colored optical signals to form wavelength-division multiplexed (WDM) signals. Transponders connected to the ROADMs' add/drop ports convert noncolored optical signals to colored optical signals (and vice versa). Dedicating transponders to given ports degrades the node's ability to route around network failures. Example embodiments of the invention include an optical node and corresponding method for routing optical signals within an optical node that compensate for this inflexibility. The optical node may include two ROADMs to transmit respective WDM signals onto at least two internode network paths and a routing module that can direct channels of the same wavelength along different internode network paths. Advantageously, a transponder may transmit (receive) different signals at the same wavelength to (from) different network node interfaces within the optical node, thereby improving the optical node's ability to route around network failures.

摘要： In today's reconfigurable optical add/drop multiplexer (ROADM) based optical node, transponders associated with the ROADMs' add/drop ports are dedicated to a given network node interface. Dedicated transponders reduce the flexibility to route around network failures. Example embodiments of the invention includes an optical node and corresponding method for routing optical signals within an optical node. The optical node may include at least two ROADMs to transmit respective wavelength division multiplexed (WDM) signals onto at least two inter-node network paths and at least one add/drop module including add ports to direct add wavelengths received from tributary network paths to each of the ROADMs via intra-node network paths to allow the wavelengths to be available to be added to the inter-node network paths. Advantageously, a transponder may transmit and receive to and from different network node interfaces within the optical node, thereby improving the optical node's ability to route around network failures.

摘要： An example embodiment of the invention includes a method and apparatus for supporting fiber span loss and dispersion measurements in the presence or absence of dispersion compensation elements (DCE). The technique may be used to configure a network link by accessing an optical signal at an ingress side of a connection point for a DCE coupling an egress side of a fiber span at the ingress side of the DCE to an optical amplifier at a connection point for an egress side of the DCE. The technique may include determining chromatic dispersion of the fiber span based on the optical signal and reporting information associated with chromatic dispersion. As a result, the technique may be used, for example, during initial system installation when user data signals and the DCE are not present as well as after the network begins carrying user traffic and after a DCE has been installed.
