Abstract:

An analog coherent subcarrier multiplexing system for video transmission using frequency modulation of both the subcarrier and optical carrier is analyzed. Theoretical receiver sensitivity for realistic values of receiver noise and phase noise is approximately -41 dBm for 50 channels and -25 dBm for 100 channels.
