提出了一种采用WSS作为远程节点的可重构WDM-OFDM-PON。该系统在发射机处采用光梳源，同时支持频谱效率高的SSB-OFDM和高比特率的DDO-OFDM。在30公里的SSMF上进行传输，我们表明具有虚拟载波的DDO-OFDM在相同的接收灵敏度和相同的DAC下提供三倍的数据速率。在采用ddoofdm的情况下，原始数据速率可达31.25 Gb/s/λ。
A reconfigurable WDM–OFDM–PON employing a WSS as a remote node is proposed. The system, which employs an optical comb source at the transmitter, is shown to support both spectrally efficient SSB-OFDM and high bit rate DDO-OFDM. Transmission over 30 km of SSMF is performed and we show that DDO-OFDM with a virtual carrier offers three times the data rate for similar receiver sensitivities and the same DAC. A raw data rate of 31.25 Gb/s/λis achieved in the case where DDO-OFDM is employed.
