Experimental results of 256QAM signal transmission by DAVIC 1.0 with cw carrier interference and Composite Triple Beat(CTB) in a transmission line are described. We have obtained the required condition that D/U of a cw carrier interference level is more than 36dB and CTB is less than -50dBc in order to keep BER of less than 1×10^<-4> without forward error correction.
