Radio frequency passive optical network with broadband wireless and optical transmission amalgamation access

Abstract

The invention provides a radio passive optical network accessed by converging of broadband wireless and optical transmission. The invention comprises an optical line terminal, an optical network unit and an optical distribution network. The optical line terminal and the optical network unit are connected through the optical distribution network. The optical line terminal is installed with a wireless signal active modulating module and demodulating module, and the optical network unit is installed with a bilateral antenna, a wireless signal passive modulating module and demodulating module. The technology combines the point to several point-to-multipoint transmission characteristic of the wireless and PON baseband service, solves the problems of blind zone of wireless access and low interference killing feature (relative to optical fiber).

Description

technical field

[0001] The invention relates to the field of optical fiber communication technology, wireless communication technology and computer network communication, in particular to a data transmission method combining passive optical fiber access network and wireless transmission technology. Background technique

[0002] With the advent of the 3G (third generation mobile communication) era, wireless communication technology is developing from narrowband communication to broadband. When wireless access technologies such as 3G and WiMAX (Worldwide Interoperability for Microwave Access) are applied to the access of densely populated large communities or large buildings, they will face the problem of wireless coverage blind spots. The increase of relay equipment such as repeaters also means the increase of maintenance costs. Therefore, solving the problem of signal transmission and coverage area in wireless access is a promotion for the rapid development of wireless acces...
