摘　　要：随着传输网的建设规模不断扩大,为了满足用户需求,对光传送网(Optical Transport Network,OTN)业务和现有同步数字体系(Synchronous Digital Hierarchy,SDH)传输网的有效结合进行探析。根据OTN技术与SDH网络特有的优势与特点设计组网方案,基于融合组网方案研究网络规划,有效融合OTN业务与现有传输网络。对网络输入层的传送带宽进行测试,测试结果表明OTN与SDH融合组网既能满足用户大量业务接入端口的需求,又具备高效的网络业务信息传输能力。With the continuous expansion of the construction scale of transmission network,in order to meet the needs of users,this paper analyzes the effective combination of Optical Transport Network(OTN)service and the existing Synchronous Digital Hierarchy(SDH)transmission network.According to the unique advantages and characteristics of OTN technology and SDH network,the networking scheme is designed,and the network planning is studied based on the integration networking scheme,so as to effectively integrate OTN services with the existing transmission network.The transmission bandwidth of the network input layer is tested,and the test results show that the OTN-SDH integration network can not only meet the needs of users for a large number of service access ports,but also have efficient network service information transmission capability.
