Abstract :
It has been suggested that the level of cross-phase modulation (XPM) produced in erbium-doped fiber amplifiers (EDFA´s) may be greater than that produced in the transmission fiber. We measure and compare the levels of XPM produced in an EDFA to that produced in both dispersion-shifted fiber (DSF) and conventional transmission fiber for a 10-Gb/s L-band wavelength-division-multiplexed system. Our results show that, for a system with twenty channels, the levels of XPM produced by our amplifier was negligible compared to that from the DSF, and a factor of approximately nine smaller than for the conventional fiber.
