| 摘 要： | 波分复用无源光网络(WDM-PON)是一种容量大、易升级、网络安全性高的光接入网技术。利用正交频分复用(OFDM)调制技术在传输速率、距离和色散容限方面的优势,提出一种基于偏振复用的WDM-OFDM-PON,同时在光网络单元(ONU)中实现了无光源的无色设计。仿真实验表明该系统可以在50km单模光纤上利用每一波长实现下行10Gb/s、上行5Gb/s的双向传输。

| Abstract: | Wavelength division multiplexing passive optical network(WDM-PON) is an optical access network with the advantages of large capacity,easy upgrades and security.With the superiority of Orthogonal Frequency Division Multiplexing(OFDM) in rate,distance and dispersion tolerance,WDM-OFDM-PON by polarization division multiplexing was proposed,and colorless design without light source was achieved in Optical Network Unit(ONU).The simulation results show that the two way transmission of 10Gb/s in downlink and 5Gb/s in uplink can be achieved using each wavelength in single mode fiber of 50km. |
