Abstract :
Lightwave-subcarrier-multiplexed (SCM) transmission systems can provide high-capacity and low-cost delivery of both current and future advanced TV signals. Compatibility of SCM technology with existing baseband digital transmission equipment would eliminate the need for a separate analog distribution network and thereby permit a more graceful evolution to a broadband integrated digital services network (B-ISDN). One version of a hybrid system whereby SCM video and baseband digital signals are simultaneously transmitted by a single laser diode, and the technical issues related to such an implementation are considered. An experiment is discussed in which the three color components of a high-definition TV (HDTV) signal and a baseband 622.08-Mb/s SONET STS-12 rate data signal are transmitted simultaneously by a DFB laser diode via frequency-modulated (FM) subcarriers, over 2 km of a single-mode fiber
