| Abstract: | The assumption of upgrading of Guangzhou-Shengzhen synchronous digital hierarchy (SDH) 622 Mbit/s ring transmission network is described in this paper. The plan would be realized by applying the existing optical fiber cable routes (Guangzhou-HongKong and Guangzhou-Fuzhou optical fiber cable routes)in Guangzhou and Shengzhen area. Comparisions are made between PDH and SDH equipment as well as the method of transmission on a line and on a ring. The economic effect of the longest transmission distance between two stations in a ring network is evaluated with the diagram given in this paper. The main technical specification of the equipment is listed finally. |
