Abstract

The invention discloses a multi-service access system and method based on a PON and relates to the field of optical fiber access. The system comprises a local side macro base station, GPON local side OLT equipment, an ODN and at least one far-end RF light device. A near-end light module disc is connected to each far-end RF light device through an optical fiber link and the ODN. The near-end light module disc comprises a near-end duplexer, a near-end monitoring unit and a near-end light switching unit. Each far-end RF light device comprises a far-end light switching unit, a far-end monitoring unit, a power amplifier, a low-noise amplifier and a far-end duplexer. Wireless signals of the local side macro base station extend into families of users through a radio frequency remote technology, a femto base station is formed, wireless access providing a wireless terminal solves the problem that optical fibers are repeatedly placed through fiber to the home and an optical fiber repeater, the building cost of an operator can be greatly lowered, and the data speed of a wireless terminal user can be obviously improved.

Description

technical field [0001] The present invention relates to the field of optical fiber access, in particular to a multi-service access system and access method based on a PON (Passive Optical Network, Passive Optical Network) network. Background technique [0002] From FTTC (Fiber To The Curb, Fiber To The Curb) to FTTB (Fiber To The Building, Fiber To The Building), and then to FTTH (Fiber To The Home, Fiber To The Home), fiber access is constantly approaching the user premises. Fiber-to-the-home is currently a large-scale construction of major operators. The access method is given as the ultimate solution. It not only inherits the characteristics of optical fiber transmission with large communication capacity, low loss, and strong anti-electromagnetic interference. Because the entire optical link uses passive components, it has the characteristics of simple deployment and convenient maintenance. This access method can solve the high-speed access of user voice services, networ...
