TY - CONF AB - A coding scheme called diode is compared with duobinary signalling and with normal binary transmission. It is shown that the diode coding suppresses the FWM products of a three channel DWDM system and this reduction against that achieved with duobinary coding is presented. The results presented show how the average level of the FWM products relative to the average levels of the three optical carriers vary over the channel spacing range. The suppression observed is about / dB more than that achieved with duobinary modulation and is greater for narrow channel spacing.
