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
Wavelength division multiplexing (WDM) is to two or more different wavelengths of light carrier signal (carry all kinds of information) in the sending end the multiplex (also called joint wave detector, Multiplexer) join together, and coupled to the optical line the same root of optical fiber transmission technology In the receiver, the solution multiplex (also called wave separator or say to multiplex, Demultiplexer) will all the wavelengths of light carrier separation, and the optical receiver for further treatment to restore the original signal. This in the same root fiber transmission at the same time two or many different wavelength light signal technology, called WDM.

子变压器，输入为AC220V，输出为AC12V，功率可达50W。它主要是在高频电子镇流器电路的基础上研制出来的一种变压器电路，其性能稳定，体积小，功率大，因而克服了传统的硅钢片变压器体大、笨重、价高等缺点。
The sub transformer, input AC12V, AC220V, output power up to 50W. It is primarily developed on the basis of high-frequency electronic ballast circuit of a transformer circuit, its stable performance, small size, big power, thus overcoming the traditional silicon steel sheet transformer body is big, bulky, the price of the disadvantages.
