Abstract

Subcarrier multiplexed (SCM) optical communication systems represent a very attractive approach to the design of wideband distribution systems.¹ SCM systems provide a way to exploit the multigigahertz bandwidth potential of single-mode optical fiber and optoelectronic components using well-established microwave technology. They also offer a highly flexible way to design broadband systems which can accommodate both analog and digital^1–4 modulation formats and can evolve in step with expected changes in video technology. We present the performance results of a twenty- channel SCM system in the 2-6-GHz frequency band over a 9-km single-mode fiber link. Each data channel was modulated using frequency shift keying (FSK) at 100 Mbit/s.
