A frequency-division-multiplexing technique for digital baseband and AM/64QAM subcarrier-multiplexed signals using a super wideband optical FM converter

摘要

Fiber-optic access system integration is key to providing various kinds of services to home users. The combination of ATM- and SCM-PON systems is essential to support a high-speed data service and analog/digital video distribution services. From this viewpoint, we describe experimentally obtained results for frequency-division-multiplexed signals consisting of digital baseband and subcarrier-multiplexed signals. The experiments were carried out using 156 Mb/s baseband signal and an FM-converted signal containing AM and 64 QAM signals. An FDM signal consisting of 156 Mb/s baseband, 30 carriers of 64 QAM and 30 carriers of AM was successfully transmitted.
