Demonstration of four-wave-mixing induced crosstalk cancellation in 10-Gbit/s phase locked multi-carrier OOK signals transmission

Abstract

This paper introduces a technique to suppress FWM-induced crosstalk and demonstrates its performance as applied to phase locked 10Gbit/s OOK-signal 6-carrier transmission. The initial carrier phases are set to cancel out 56% of the generated crosstalk. Successful transmission over DSF is achieved with a power penalty of 1dB even though the crosstalk level was -15dB.
