摘要：
The use of a high-power 1.5 mum DFB laser and a linearised Ti: LiNbO2 Mach-Zehnder modulator as a transmitter in a CATV lightwave system is reported. The performance is compared with directly-modulated 1.5 mum-wavelength DFB lazers in 60 channel transmission over 16 km of conventional singlemode fibre. The transmission of 52 high-fiequency channels is demonstrated (450-750 MHz) in anticipation of futum CATV upgrades.
