摘要
波分复用(WDM)是将两种或多种不同波长的光载波信号（携带各种信息）在发送端经复用器(亦称合波器，Multiplexer)汇合在一起，并耦合到光线路的同一根光纤中进行传输的技术；在接收端，经解复用器(亦称分波器或称去复用器，Demultiplexer)将各种波长的光载波分离，然后由光接收机作进一步处理以恢复原信号。-Abstract

basic concept of OFDM is quite simple [4]–[7]. Data is transmitted in parallel on a number of different frequencies, and
as a result the symbol period is much longer than for a serial
system with the same total data rate. Because the symbol perio

The all-optical wavelength conversion gives flexibilities to the optical fiber communication
networks, especially to the wavelength-division-multiplexed (WDM)-based ones, because it allows
them to reuse wavelengths and to avoid wavelength channel
