Abstract
In a two-channel 560 Mbit/s DPSK system with optical broadband amplifiers the effect of channel spacing is investigated. The main crosstalk mechanism is independent of the amplifiers. It is caused by the spectral overlap of the two channels. No additional crosstalk due to four-wave mixing in the amplifier is found.
