    • An apparatus and method for analyzing the spectrum of a wavelength division multiplexed (WDM) optical signal, in wavelength division multiplexing (WDM) optical transmission systems, are provided. An optical filter includes an input unit for receiving a wavelength division multiplexed (WDM) optical signal via an optical transmission medium and outputting optical signals that have different incidence angles according to the wavelengths of the optical signals. Also, the optical filter includes a filter for receiving the optical signals from the input unit and separating the WDM optical signal into optical signals having different wavelengths using the difference between resonance lengths according to the different incidence angles. In order to analyze the spectrum of an optical signal, the optical signal is made incident upon etalon at different incidence angles according to the wavelengths of the optical signal, and the resonance length between two mirrors of etalon is varied according to the wavelengths of the optical signal. Accordingly, an optical spectrum can be obtained by detecting optical signals having different wavelengths.
    • 提供了一种在波分复用(WDM)光传输系统中分析波分复用(WDM)光信号的频谱的装置和方法。 光滤波器包括用于经由光传输介质接收波分复用(WDM)光信号的输入单元,并根据光信号的波长输出具有不同入射角的光信号。 此外,滤光器包括用于从输入单元接收光信号的滤波器,并且使用根据不同入射角的谐振长度之间的差分将WDM光信号分离成具有不同波长的光信号。 为了分析光信号的光谱,光信号根据光信号的波长以不同的入射角入射在标准具上,并且标准具的两个反射镜之间的共振长度根据光学信号的波长而变化 信号。 因此,可以通过检测具有不同波长的光信号来获得光谱。
