Abstract
A novel architecture of bidirectional wavelength division multiplexed passive optical network (WDM-PON), based on forward error correcting (FEC) scheme, has been proposed and analyzed theoretically. This configuration is made economical by employing injection locked Fabry-Perot laser diode (FPLD) for direct modulation at transmitter end and reflective semiconductor optical amplifier (RSOA) as remodulator at receiver end. Reed-Solomon (RS) codec is preferred in the design to comprehend the FEC scheme. The RS (255, 251) codec is realized by field-programmablegate- array (FPGA) with the help of VERILOG programming. Excellent transmission performances of 10 Gbps datasignal over maximum of 20 km SMF in downlink and uplink are obtained by the low bit error rate (BER) values and significant eye diagrams at BER analyzer.
