Abstract
Rayleigh crosstalk caused by the double Rayleigh reflection of a signal is investigated in long systems consisting of distributed Raman amplifiers. A simple equation for the crosstalk-to-signal ratio is presented and it is sh own that bidirectional pumping reduces crosstalk. Power penalties arising f rom the crosstalk are evaluated using a Gaussian crosstalk model.
