Abstract :
We have proposed an improved OSNR measurement technique called optical polarization splitting based on the polarization-nulling method. The test results with Tellabs ultra high speed networks showed that the proposed technique could measure the OSNR accurately at all modulation formats even when the signal was significantly depolarized due to PMD and nonlinear birefringence.
