摘要: We have proposed a new optical monitoring technique that employs an optical time-domain reflectometer combined with an acoustooptic switch and concatenated fiber Bragg gratings to achieve simultaneous optical monitoring and fiber surveillance for wavelength-division-multiplexed (WDM) networks. The optical power monitoring with dynamic range of 26 dB and accuracy less than or equal to 0.1 dB for each WDM channel and the feasibility of simultaneous optical monitoring and fiber surveillance in WDM networks have also been demonstrated by using this technique.
