不同设备构建SDH光通信网的探讨

The discussion on the SDH optical communication grid with the difference devices

多厂家设备组网是商业驱动的必然模式，也是技术竞争和保证业务安全稳定的必要要求。不管是运营商还是各行各业的通信专网，多厂家设备共存，互联互通，相互组网都是客观存在的。然而，在应对突发灾害或故障时，由多厂家设备组成的网络在管理能力上却暴露出了许多难以克服的弊病，特别对于承栽着各种重要电力实时生产业务的专网通信网络，由于光缆敷设和网架结构的特殊性，这些弊端就越发突出。基于贵州电力SDH光纤主干通信A网，结合08年处遭遇冰灾时出现的问题，分析在多厂家共存的环境下网络的抗灾应对能力，冰灾分析中阐述了规避这些问题的一些方法。

It is an inevitable model of the business drive to construct the grid by various plants devices, which is a necessary requirement of the technical competition and the guarantee of the safe and steady op- eration as well. No matter the operator or the communication grid of various trade, the device coexistence and interaction of various plants is objective. However, the insurmountable drawback of the management on the grid constructed by various plants devices is exposed confronting the sudden calamity or break- down, especially on the special net communication grid undertaking all kinds of the crucial electrical real time manufacture operation, due to the particularity of the optical cable pavement and the wire frame con- struction, the disadvantage is more and more prominent. The paper based on the a communication grid of Guizhou power SDH fibre -optical backbone, combining with the problem appearing in the 08 ice dam- age, analyzes the anti - calamity reply ability of the grid in an atmosphere of various plants coexistent. In analysis of the ice damage , the paper presents some methods to avoid theses problems Key
