Abstract:
A method and device for improving a signal-to-noise ratio measurement range of a monitoring device operating on a fiber optic network. The method includes receiving a wavelength division multiplexed optical signal including a plurality of optical signals centered at different wavelengths within a range of wavelengths. The wavelength division multiplexed optical signal is dispersed to form a discrete power spectrum. The discrete power spectrum is measured, and data representing the measured optical signals is generated. The measured optical signals include a point spread function response of a pixelated optical detector. A deconvolution operation is performed on the generated data to create an estimate that is more representative of the power spectrum by compensating for the point spread function of the pixelated optical detector.
Abstract:
A monitor device and method for monitoring operating conditions of a wavelength division multiplexed optical signal. The monitor device includes an optical engine for receiving the multiplexed optical signal and generating a plurality of demultiplexed optical signals. An array of optical detectors is disposed to receive the demultiplexed optical signals from the optical engin e. The demultiplexed optical signals form spots on the array of optical detectors. At least one spot is wider than a center-to-center dimension spanning two optical detector elements in the array of optical detectors.
