波分复用无源光网络(WDM-PON)实现了点到点的连接,可为每个用户提供专有波长,被普遍认为是未来宽带接入的代表性技术。WDM-PON中采用的调制器,既要实现“无色”调制,又要保证系统性能,以降低成本。为此,在强度调制直接检测单模光纤(IMDD SMF)连接系统中,采用半导体光放大器(SOA)作为强度调制器,分析了调制信号与波长的相关性,提出了实现无色自适应调制光正交频分复用(AMOOFDM)传输的优化工作条件。
WDM-PON enables point-to-point connections and provides each user with a proprietary wavelength, which is widely considered as a representative technology for future broadband access. Modulators used in WDM-PON not only achieve “colorless ” modulation, but also to ensure system performance, in order to reduce costs. For this reason, a semiconductor optical amplifier (SOA) is used as an intensity modulator in the IMDD SMF connection system, and the correlation between the modulation signal and the wavelength is analyzed. A method is proposed to realize colorless adaptive modulation light Optimized Operating Conditions for Orthogonal Frequency Division Multiplexing (AMOOFDM) Transmission.
