According to the development guidelines of broadband access network for China Unicom, most of the fixed broadband access network should be constructed by optical fiber, and the priority should be given to the use of PON technology. With the access node geting gradually closer to the user, FTTH will be realized, and the bandwidth will

The traditional access network technology can’t meet voice, video and data access of fullservice, passive optical network technology (PON) arises at the historic moment and becomesthe big focus of operators. PON technology is regarded as the best technology to construct thefull service access network. But simple PON technology still can’t meet the needs of thediverse

This paper has raised the possibility of using EPON technology in the construction ofcampus wireless network. It is aimed at the status of the lack of pipeline resources whenmobile operators enter into the traditional area of the existing fixed-line operators and build awireless network. With the increasing advance of optical network terminal to the users,

In recent years, the use of burst mode data transmission is increasing in digital communication systems.These systems use point-to-point and point-to-multipoint connections over optical, wireless, and coaxial media. Designers in worldwide are working on local-access approaches using time-division multiple-access (TDMA) technology. Some examples include using passive optical network (PON) to realize fiber to the home,

Passive optical network (PON) technology is the key technology to break bottleneck of “the last kilometer”; however, the problem of the security of PON has not been solved well. Since the optical line terminal is always active in the whole procedure of communication, i.e., OLT can easily capture the information exchanging between any two of

With the rapid development and popularity of Internet, core network is rapidly evolving to Gigabit Ethernet, while the rate of end-user is also developing with each passing day. However, the access network has made little progress which has become the bottleneck of the whole network. As a result, the access network technology has been attached
