Research Of The Application Of The Dense Wavelength Devision Multiplexiong Optical Transmission System

All well known, Accompany the Internet rapidly spreading and developing, the IP data bussiness is growing up explosive.Thus,all kinds of new business(AS VOD, Band Width Rent, VPN et.) constantly emerged, The demands for the network bandwidth and reliance is becoming strictly more and more. So the DWDM's feature of the mass capacity,the Ultra Long Hop Transmission and with stable preformace is taking advanced advatage in Internet developing, It is the important base support platform for the Next Generation Network.On the basis of the one project of DWDM, the article introduced the theories, application and the newest development in DWDM technology. The main point of the article is the principle of composing network, the rule & standard of the network design and the demand of the network application, While proved the reliability of the DWDM system by testing performance of the Optical power, Optical Signal Noise Ratio, Error Bits Ratio. By studing, I have found a number set of method in DWDM network design, application and test.
