Latest Patents
One of his latest patents is titled "Method and apparatus for optical amplifier gain and noise figure." This innovative method improves the measurement of noise figure and gain of optical amplifiers by transforming the amplifier into an oscillator through optical feedback with known loss. The feedback system includes a tunable filter for wavelength control and a variable attenuator for gain control. By measuring the output power at a specific wavelength and analyzing the noise characteristics of the output signal, Farber's method allows for comprehensive characterization of the optical amplifier.
Another significant patent is "Method and apparatus for monitoring wavelength multiplexed optical." This method determines the signal-to-noise ratio of an optical signal by modeling the noise floor based on amplified spontaneous emission (ASE) accumulated along the link. The ASE wavelength dependence is represented by a mathematical function with limited parameters, derived from noise floor measurements. The system utilizes fiber grating filters and an optical circulator to sample and direct the reflected ASE light, allowing for precise monitoring and computation of the signal and noise characteristics.
