Abstract
With the industry's rapid development of information technology, people information application requirements for video communications, electronic commerce, information transmission industry increased significantly, the network continues to promote the development of high-speed broadband. Today, the rapid development of backbone network technology has become more sophisticated, the backbone has been developed to provide a stable broadband service skills. So located network service access network between the client side and attention. The new fiber-optic broadband access available broadband technology has great potential for development, support for long-distance transmission, strong anti-interference advantages, the future optical access network technology has the potential for long-term development and will continue to spread to all sectors of the access network in system.
This paper describes the background and current situation of the development of access network technology, and describes the access network technology development of major significance. Several analyzes the main access technology digital subscriber loop technology, Ethernet-based copper technology, wireless access technology, optical fiber access technology features. Focus on the Ethernet-based Passive Optical Network (EPON) access network technology, learning the basic working principle, key technology, and analyzes the advantages EPON technology. Finally, for EPON Technology and Industrial Ship access network the corresponding design.
Key words: Access network ；fiber-optic broadband network ；EPON ；research
