Abstract
A processor of an apparatus is configured to apply one or more control algorithms using estimated data to adjust the one or more control parameters of a section of an optical fiber network. The estimated data are derived from measurements of optical signals in the section and from knowledge of the section. The estimated data is a function of optical nonlinearity and of amplified spontaneous emission.
Claims20
An apparatus comprising:
- circuitry to support an optical service channel;
- and
- a processor configured
- to evaluate gradients of an objective function using measurements of optical signals in a section of an optical fiber network and using estimated data derived from the measurements and from knowledge of the section, wherein the estimated data is a function of optical nonlinearity and of amplified spontaneous emission;
- and
- to apply one or more control algorithms using at least the gradients to adjust one or more control parameters of the section,
- wherein the measurements include per-channel optical power or power spectral density and the measurements of per-channel optical power or power spectral density are taken at fewer geographic locations than a number of geographic sites in the section having optical amplifier devices, and
- wherein the objective function includes effects of per-channel optical powers of a plurality of channels at a geographic location in between geographic locations of per-channel measurement of optical power or measurement of power spectral density.
