Abstract
The principle and design of a cost-effective optical fiber communication system are proposed to support hybrid digital/analog signal transmissions, by simultaneously using pulse-width modulation (PWM) for the analog signal and two-level pulse-amplitude modulation for the digital signal, while essentially requiring the same channel bandwidth as a conventional analog PWM system.
