主要介绍了近年来高速光纤通信中采用的关键复用技术，包括波分复用(WDM)和正交频分复用(OFDM)等复用技术的发展历史，组成结构和所使用的器件。因为波分复用网络需要在一根光纤中传输多路信号，所以系统对组成的器件的性能较普通光源有更多的要求，而光波分复用器则是该技术的关键所在。O-OFDM技术是在射频领域长期使用的技术，近几年把该技术应用到光纤通信系统中减小了网络串扰，增大了传输稳定性。通过这些技术，光纤网络在提高数据传输稳定性和增加传输容量上获得了成倍的增长。

Main introduce the key multiplexing technology in optical communication, including the development of wave divid-ed multiplexing and orthogonal frequency division multiplexing technology, the structure and the devices used in the system. Be-cause WDM network can transmit multichannel signal only in one fiber optic, the system need more performance requirement to the component, and the optical communication multiplexer is very important in the system. Optical OFDM was used for a long time, recently years it has used in the fiber communication to reducing the ISI and ICI and improving the system stability. Through these technologies the fiber communication network is improving data transmission stability and increase the transmis-sion capacity of the growing exponentially.
