Performance analysis of multichannel 16/64-QAM CATV distribution network using semiconductor optical amplifier as an external modulator

It is shown numerically that by using a TWSOA as an external modulator at the transmitter end of a multichannel 16/64-QAM fiber-optic CATV link, up to 400/600 MPEG2 video channels could he transmitted with a total link budget of 34/28 db.
