光纤通信的复用技术的研究
光纤通信的复用技术的研究(任务书,外文翻译,论文15000字)
[摘 要] 在光纤通信中，复用技术被认为是扩展现存光纤网络工程容量的主要手段。复用技术主要包括时分复用TDM（Time Division Multiplexing）技术、空分复用SDM（Space Division Multiplexing）技术、波分复用WDM（WaveLength Division Multiplexing）技术和频分复用FDM（Frequency Division Multiplexing）技术。但是，因为FDM和WDM一般认为并没有本质上的区别，所以可以认为波分复用是＂粗分＂，而频分复用是＂细分＂，从而把两者归入一类。

The fiber optic correspond by letter of reply
with the technical research
[Abstract] In fiber-optic correspondence, reply with it is main means that expands the existing fiber-optic network engineering capacity that technique is think.Reply to the mainly include the with the technique reply the to use the TDM (Time Division Multiplexing) the technique separately, the empty reply the separately to the reply to the use the WDM ( WaveLength Division Multiplexing) technique and Frequency the s to the reply to the use the FDM (Frequency Division Multiplexing) technique the separately with the SDM (Space Division Multiplexing) technique, the a cent .But, the Frequency replies separately the use is “ that a the to subdivide ” the FDM and WDM think to have no essential differentiation generally, so can think it is “ that a cent replies to use thick cent ”, thus return both into together.
