100G OTN Network Design And Implement In Deyang Area

In recent years,with the rapid economic development of deyang area,promote the development of the Internet TV business in this region;in order to enhance the native competitiveness of Internet TV business,Deyang Mobile Company is promoting the 4G-services and Government and Enterprises Clients businesses on the one hand,on the other hand,sparing no effort on the solution of PTN convergence volume boom.For this,the OTN Network was brought in by Deyang Mobile,however,the previous 40*10G OTN can not fulfill the business boom,thus,Deyang Mobile planned to construct the 100 G optical transmission network.In this paper has completed the design and test of Deyang 100 G OTN Network,the main contents are:1.Firstly,in this paper,we introduce the main and key technology of 100 G OTN Network,and the network architechture;especially focus on the 100 G modulation technique,coherent reception,DSP-technology,soft decision forward error correction technique which are applied in between 100 G OTN and previous OTN networks;then,we analyze and study the existing PTN,OTN and other networks,combined with the characteristics of Deyang region and businesses distribution,then predict the future business development directions,finally settle down the overall construction program of Deyang Mobile 100 G network.2.Secondly,fucusing on the overall program,we made key analysis and study on the wavelength resources scheduling,equipment selection and protection,moreover,we proposed relevant standards and recommendations on engineering construction indicators.3.According to "China Mobile Optical Transmission Network Test Specification",the network had been tested by many indicators,which includes: on the optical performance index(receiving sensitivity,overload optical power,average optical transmitted power,center frequency,and center frequency deviation);on protection switching(1+1 protection switching test,dual channel shared fiber bidirectional ring network protection test);on system test(long-term packet loss rate,OSNR,24 h long-term BER test,output and input jitter test).Currently,the OTN network construction has been basically completed,after testing,all the indicators have reached the standard,this network is expected be delivered.
