The composite triple beat is all the discrete third order intennodulalion distotions (lMD 3 ) produced at a channel or around a carrier when two or more signals are input to a device or system with non-linearity.The composite triple beat that fall directly onto the channels designated for use can limit the performance of the radio-over-fiber system m.til,:) suppress or interfere destructively with nlrriers that reside in these channels.Arranging the channels to be used in accordance to the Golomb Ruler's r' n l1rks was found to reduce the composite triple beat, generated b} an optical system employing intensity modulation, that fell directly onto these channels as compared to positioning them in equidistant based on a simple experiment performed involving 14 used channels.The decrease in CTB levels led to CTB reduction factor of above OdB and decrease in carrier suppression.
