ABSTRACT
Information industry is the world's economy the most dynamic and
competitive industries in the world, it affects the way people live
and the quality of life. Access network is the user network access to
metro/backbone bridge. With the popularization and application of SDH
technology and large-scale development of ATM technology,
telecommunications network backbone has been basically realized fiber,
broadband and digital.
Firstly, an overview of access network technology. By definition,
the physical reference model, access technology, trends and other
related content outline indicating the access network, optical access
network is the inevitable trend of technological development.
Secondly, this in-depth study of the copper access and optical access
to both the access network access technology, and focused on
particular passive optical fiber access networks (PON - Passive
Optical Network) and the current mainstream FTTx (Fiber To The x/some
place) .Then, the paper "Light of Copper" solution for specific
research and analysis. mainstream operators first kilometer access
networks are still largely dominated by twisted pair copper network,
in order to meet the growing bandwidth demand, to achieve optical
access, the existing copper access network must be modified.
Finally,on the optical access network technologies are introduced,
consistent with TMN requirements about the access network management
system structure and function, and the realization of the access
network of network management.
KEY WORDS: access network, optical fiber communication, PON
