Abstract :
We have measured cross-phase modulation (CPM) at L-band in both dispersion shifted fiber (DSF) and conventional fiber (CF) and compared it to that produced in an amplifier. Our measurements, intended to simulate a twenty channel 10 Gb/s WDM system with 100 GHz channel spacing, show that the CPM produced in our L-band amplifier is negligible compared to that from DSF and a factor of nine lower than that from CF. We operate all twenty channels simultaneously in order to realistically mimic the cross-talk of a fully populated WDM system. These results show that CPM produced in L-band amplifiers is not necessarily a problem
