Abstract
In this paper we 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.
Conclusions
A transmission system is established for triple play (voice, video and data) with centralized OFDM-FTTH BPON based on an external modulator. We have Transmitted voice and internet data by using PRBS generator at the data rate of 1.25Gbps at a BER of 1×10- 40 and video is transmitted with the help of 4 QAM modulated OFDM signal at the data rate of 10Gbps at a BER of 1×10-3. The 1.25Gbps voice signal, 1.25Gbps data signal and 10Gbps video signal have been transmitted over 20km single mode fiber (SMF) successfully in a FTTH network.
