Abstract: An apparatus for monitoring extinction ratio (ER) of optical signals comprises an optical spectrum analyzing unit, an ER monitoring control unit and an ER monitoring output unit. The optical spectrum analyzing unit measures two peak values corresponding to level one and level zero of optical signals from an optical coupler, and obtains two wavelengths for the two peak values.

With a relation formula of the wavelength difference, the ER monitoring control unit estimates an optimal resolution bandwidth for setting up the optical spectrum analyzing unit. As such, the optical spectrum analyzing unit measures two optical powers corresponding to level one and level zero of optical signals. With the two optical powers, the ER monitoring output unit computes an ER value.

Abstract: A non-sampling-based Q-factor measuring apparatus and method use a power conversion module to transform the power variation of inputted optical signals in time domain into the variation in other domains, such as optical wavelength, optical polarization and different output ports of optical elements. Taking optical wavelength as an example, different levels of power variation respond different outputs of wavelength variation through the use of a power-to-wavelength conversion module. An optical filter then separates the inputted optical signals with different wavelengths. The power average of a wavelength for its corresponding optical signals is further calculated by a photo detector. Thereby, the information of the power variation for the inputted optical signals at levels 1 and 0 can be obtained, and the Q-factor for the inputted optical signals is easily measured.
