Abstract


This paper describes Malaysia’s recent approach in fiber-to-the-home (FTTH) network through the utilization of pre-erbium doped fiber amplifier (pre-EDFA) in improving Community Antenna Television (CATV) signals in point-to-point (P2P) topology. The optical network unit (ONU) input power and the CATV output quality is observed on a television (TV) unit display each time the EDFA current setting is changed, for before and after a second EDFA is installed between transmitter and ONU (pre-EDFA) for a Malaysian scenario. Before pre-EDFA is installed, the dynamic range is not obtained since the saturation point is not clear, and thus could not be pointed yet. The findings after the pre-EDFA is installed is that, the dynamic range is found to be equals to -17.85 dBm ~ 3.03 dBm for fiber spool used length at 15.225 km. The dynamic range is selected based on the ONU input power when the CATV signal’s output is good and clear. The result shows that pre-EDFA improved the CATV signals displayed for a Malaysian scenario.
