Abstract:
In this letter, a WDM-OFDM-PON architecture using LDPC code is brought up to increase transmission range and system performance. In optical line terminal (OLT), LDPC-coded OFDM signal at 10-Gb/s is transmitted as downstream. At each optical network unit (ONU), the optical OFDM signal is demodulated with direct detection, and on-off keying date at 2.5-Gb/s is returned as upstream. Simulation results show that the transmission distance could exceed 20-km with negligible penalty.
