Abstract

In this manuscript, we have investigated different optical amplifiers like RAMAN, Semiconductor Optical Amplifier (SOA) and EDFA for bidirectional hybrid (WDM/ TDM) Passive Optical Networks (PONs) at 10 Gbps data rate with 128 numbers of Optical Network Units (ONUs). The performance of the system is enhanced with polarization modulation with 16-QAM technique. To make the system simple, a circulator is used for bidirectional transmission through the same fiber. The upstream data is transmitted at 1300 nm wavelength and downstream data is transmitted at 1550 nm wavelength. Various results for BER are shown at 40 and 50 KMs distance. It has been observed that EDFA amplifier shows better performance than SOA and RAMAN..
