In this paper, the authors have demonstrated a transmission system for triple play (voice, video, and data) with centralized Orthogonal Frequency Division Multiplexing-Fiber To The Home Broadband Passive Optical Network (OFDM-FTTH-BPON) based on an external modulator. At the one of two arms of system, voice and internet data are transmitted using Pseudo Random Binary Sequence (PRBS) generator at bit rate of 1.25Gbps .In another arm of system, video is transmitted with the help of 4 QAM modulated OFDM signal. The 1.25Gbps voice signal, 1.25Gbps data signal and 10Gbps video signal have been transmitted over 20km Single Mode Fiber (SMF) successfully.
