摘要： Systems and method include a detector communicatively coupled to a fiber span; and processing circuitry connected to the detector and configured to digitally sample and process an output of the detector, detect phase changes in the output, and identify an electrostrictive response of the fiber span based on the detected phase changes and based on a dependence of the detected phase changes with frequency. A property of the fiber span can be determined on the electrostrictive response. The property of the optical fiber can include one or more of optical fiber material type, optical fiber material property, optical fiber area, optical fiber geometry, optical fiber condition, optical fiber stress and strain, optical fiber temperature. and optical fiber radiation exposure.

摘要： Systems and methods for distributed measurement in a network implemented by an orchestrator include directing one or more modules associated with one or more network elements to each perform a subset of the distributed measurement; receiving results from at least one network element of the one or more network elements based on the directing; and detecting an event or property based on the results. The subset of the distributed measurement can be based on performance monitoring data. The method can further include shuffling assignments for the distributed measurement between the one or more modules

摘要： Systems and methods of optimizing launch power for each span in an optical system with a plurality of spans are provided. In an embodiment, a method includes varying power on a span under test of the plurality of spans; observing performance measurements related to of one or more channels, at corresponding optical receivers; and one of setting launch power for the span under test and repeating the varying and observing, responsive to the observed measurements.

摘要： An optical transmitter (102,200) is operable to generate an optical signal (260) by modulating a number N of frequency divisional multiplexing (FDM) subcarriers using transformed digital signals which are determined by applying a pseudo FDM (pFDM) transformation to preliminary digital signals representative of multi-bit symbols. Rather than experiencing the effects of the number N of FDM channels, the optical signal experiences the effects of a different number M of pFDM channels, where M≠N. In some examples, the number M of pFDM channels is less than the number N of FDM channels, and frequency-dependent degradations may be averaged across different symbol streams. In other examples, the number M of pFDM channels is greater than the number N of FDM channels, and different symbol streams may experience different frequency-dependent degradations. An optical receiver (102,300) is operable to apply an inverse pFDM transformation to recover estimates of the multi-bit symbols.

摘要： A lazy graph construction with compression includes receiving a query related to a network; one of generating a site graph for the network and accessing the site graph already in memory; performing a search on the site graph based on the query; accessing data in a database and generating, in the memory, a plurality of sub-graphs using the data, for the query; and providing a solution to the query based on the search and a search of the plurality of sub-graphs. The site graph can be at a site level and includes network elements and associated connections in the network, and the plurality of sub-graphs can be at an intra-site level including any of component-to-component connections and intra-component connections.
