- Abstract
In this letter,a 8QAM-DMT-OFDM optical access scheme is proposed and demonstrated. 8QAM-OFDM optical access signal is generated using discrete multitone (DMT) modulation, and its optical spectrum, electric spectrum before electro-optical conversion, constellation diagrams before and after transmission and bit error rate (BER) are measured. By this scheme, the system complexity and costs could be reduced .The results show that t As the transmission distance is 20 km, the value of BER of 8QAM-DMT-OFDM optical access signals is below 10-4.Therefore, this work not only reduces the complexity and cost budget of 8QAM-DMT-OFDM optical access system but also improves the receiver sensitivity.
