摘要
In this paper, the effect of phase-shifting between pumping lightand input signal light in a optical Phase-Sensitive Amplifier(PSA)ondispersion compensation for optical fiber communication systems usingPSA as In-line amplifiers is theoretically analyzed by computersimulation. From ur simulation we've got the result that Theeye-pattern degradation of the high-speed signal increase rapidlywith the accretion of fiber dispersion and also Increase with theincreasing of phase shift. But if the phase shift is controlled in acertain range, it won't affect the System performance. Otherwise, thesystem performance will be seriously degraded. At all events, theshifting Range of PSA's phase, which shifts at both sides of zero,will be half of that which shifts at only one side.
