Abstract :
We report a two-wavelength WDM analog CATV transmission system with cross talk <-60 dBc at launched power of +9 dBm/wavelength, an improvement of 13 dB over previous results. We are able to achieve this result principally by reducing the channel spacing from 8.6 nm to 2.2 nm. In addition, contrary to expectations for SRS, we find significant reduction of the cross talk by applying a 2-GHz dithering tone to the laser
