In this study, we present experimental results of bit error rate (BER) characteristics of 6Mbps QPSK signal, in the condition of various CTBs induced under fifty one VSB-AM channels optical hybrid transmission. We clarified the following items. (1)BER dependency of CTB cannot be specified by average CTB values. (2)In the case that maximum CTB values are considerd, amplitude probability distribution of CTB should be taken into account-(8)Amplitude probability distribution of CTB changes depending on modulation depth of DFB-LD.
