Abstract :
Hybrid WDM systems with both analog and digital channels are a natural choice for the video transmission applications. The effects of crosstalk in a hybrid WDM system are measured and analyzed in this letter. The required crosstalk rejection ratio is also provided with the assumption that the differences in received optical power among various channels are the same as their differences in receiver sensitivities.
