Abstract: 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.

Abstract: 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

Abstract: Systems and methods for in-service measurement of nonlinear interference on a per span basis in an optical network having a plurality of spans include steps of varying power in a span of the plurality of spans to cause small power perturbations which do not impact traffic carrying signals; observing a change in noise at an optical receiver at an end of the plurality of spans with the change due to the varying the power in the span; and determining the nonlinear interference for the span based on the change in the noise.

Abstract: 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.

Abstract: A module for use in an optical network includes one or more elements concatenated to one another; and circuitry configured to receive and store calibration data associated with the one or more elements, and transmit the calibration data to one or more processing devices for modeling of the module in a link in the optical network. The one or more elements can include gain blocks for optical amplification. The calibration data can be determined at manufacturing via testing. The calibration data can relate to determining gain and noise transfer functions of the module at various operating points.
