Abstract :
The authors describe the design and performance of all-fiber video distribution (AFVD) systems based on AM/FM FDM subcarrier multiplexing (SCM) and erbium-doped fiber amplifiers (EDFAs). The impact of applying EDFAs to SCM analog video distribution systems is investigated. AM/FM hybrid systems, which can simultaneously distribute 11 AM TV channels and 50 FM TV channels are proposed and discussed. Four-stage amplifier-branch transmission experiments are introduced. The construction and performance of a newly designed 50-channel FM tuner are also presented
