[en] In optical analog/digital multichannel CATV transmission using external modulation system, the clipping of the laser is a potential major disturbance. The clipping noise can be taken as impulsive impairment and leads to the appearance of a penalty in the BER curve. For that purpose, this paper presents a set-up based constellation analyser, which allows to characterize the penalty in the BER curve of clipping-induced impulse noise on M-QAM signal.
