Abstract

For the efficient operation and maintenance of a modern dynamic WDM network, it is necessary to monitor various parameters including the channel power, wavelength, and optical signal-to-noise ratio (OSNR), etc [1]. In particular, OSNR is an important parameter to be monitored for the estimation of the quality of transmitted signal. This paper reviews the current status of the OSNR monitoring technique based on the polarization-nulling method.
