Abstract

Increasing demand of bandwidth can be reached by employing WDM-OFDM-PON for downstream transmission, based on a tunable mode locked comb source. The WDM-OFDM-PON based on compatible SSB technique provides the required bandwidth for downstream transmission. The 12.75 Gbps compatible SSB OFDM signal is used to modulate 10 comb tones separated by 10 GHz. A spectral efficiency of 1.275 bps/Hz was achieved in conjunction with the use of low complexity electronics. Transmission over 50 km and 87 km of standard single mode fibre was successfully demonstrated. The bit error rate for transmission over 50km fibre optic cable can be reduced to a maximum extent. The transmission over the channels after 87km achieved performance below the 20% FEC limit.
