| With the rapid growth of fixed network IP service and mobile 4G service,2020 is also the first year of 5g technology.Operators' demand for transmission network bandwidth is becoming larger and larger.How to use the existing physical resources to improve the cost performance and network bandwidth of communication system and meet the growing demand for multiple services has become the focus of transmission network development.With the development of towns and villages in Yongnian County,the focus of telecommunication business has shifted from voice business to data business,which has resulted in some densely populated villages and towns,home broadband Internet access and IPTV browsing feel stuck,and the transmission capacity of individual nodes has been nearly saturated.It is an urgent task to Establish a new high-speed network that can accommodate various services and meet the needs of different users.DWDM technology can directly access to a variety of services,but also this is a good foundation for the future bright transmission network,suitable for the current situation of the Yongnian Unicom transmission network and the further development of the mobile industry.To meet people's growing demand for information.However,the zxmp M800 wavelength division system of Yongnian ZTE,which was built in2010,can barely meet the network demand of people,but individual nodes have been unable to meet the user demand.The construction of the second plane of Yongnian Unicom Company is to solve the aging and saturation situation of many equipment faced by the existing Yongnian transmission network.(1)from the perspective of wave division two plane design,a permanent year two plane design scheme based on DWDM technology was proposed.Considering the small capacity and low rate of zte one plane,the design scheme constructs a large capacity and high rate optical signal transmission network of huawei wave division two plane.On this basis,the transmission distance between the network element pairs according to the service request is studied,the most reasonable network element format is provided for the request,and the minimum frequency gap position is used as huawei 2 plane to complete the spectrum allocation process.This not only satisfies the transmission quality demand of the service,At the same time,it reduces the resourceconsumption of the spectrum needed by the service and increases the resource consumption.utilization rate of the network spectrum resource.(2)from the perspective of wave division two-plane construction,a permanent two-plane implementation based on DWDM technology is proposed.Considering the actual business differences of different network elements,according to the principles of network node configuration and planning,20 optical channel networks are constructed under the configuration of ring network nodes.On this basis,to increase the rate of different business between transmission stability,tested YongNian amplifies light wavelength division network unit emitting power value,actual network elements found 9 input power input power tend to be ideal,guarantee the good channel parameters in the network,to fulfill the requirements of engineering testing,and improve the transmission quality of business requests. |
