SDH transmission network to the traditional PDH network are incomparable advantages, Not only can be applied in the traditional telecommunications field, but also can enable the telecommunications network architecture evolved into a unified network. Based on SDH technology theory analysis, discussion of SDH Network needs to focus on the issue. And the design speed of 2.5 G local SDH transmission network. Ring topology choice, self-healing methods of two-way choice of two fiber multiplexing, Equipment Selection Huawei equipment OptiX for the main site network equipment.
