The universal application of the several classes of enterprise access technology has its insufficient place: traditional SDH / MSTP has a good multi service bearing capacity, but the cost is relatively high, mainly used are very concerned about the quality of service of high-end clients to access; xDSL access multi service bearing lack of potential to be tapped, apply only to a small amount of speech + low rate for low-end applications for the broadband; but in the end, showing a hybrid of DDN, PDH, Ethernet technologies, these technologies in multi service bearing capability, reliability, maintainability and have their own limitations, difficult to meet the needs of new period of full service access. Under the current circumstances, to build an enterprise to meet the needs of the majority of enterprises, can carry a variety of business, management, easy maintenance of the enterprise access network has become a top priority of the operators.
Along with our country copper.
In the process of development, PON network has been widely accepted by operators in terms of bandwidth upgrade, service bearer and passive network maintenance. Recently, some of the world's leading operators began to apply GPON technology to enterprise access, making GPON become the star of enterprise access program technology. So in numerous technical and operator why choose to do in the new era of enterprise applications of GPON. Analysis of the industry think, in the enterprise access scenario, GPON technology and other access technologies compared with many advantages.
