Access network implementing system and method for bearing all information services of local customer

Abstract

The invention discloses an implement system of an access network for loading all information business of resident users, which comprises a main unit, an expansion unit and a remote end unit. The invention further discloses an implement method of the access network for bearing all the information business of the resident users, which comprises the following steps: jointing and combining one or more than one kinds of signals which are sent by an information source, transmitting the signals to one or more than one remote ends through optical fiber after converting the signals into light signal branching, carrying out the electric-to-optical conversion to the light signals which are respectively received by each of the remote ends, radiating the signals to a user end through an antenna, transmitting the light signals through the optical fiber after respectively carrying out the electric-to-optical conversion to electrical signals which are received through the antenna by each of the remote ends, respectively converting the received light signals into the electrical signals, transmitting the electrical signals through dividing the signals into business RF electrical signals in different frequency ranges after integrating the electrical signals into the electrical signals. With the invention, the functions of accessing and exiting all types of user information business and the loading transmission function can be realized in resident areas only through building a physical network.

Description

technical field [0001] The invention belongs to the technical field of access networks of information communication networks, in particular to an access network implementation system and method for carrying all information services of resident users. Background technique [0002] The so-called resident access network or user access network (Customer Premises Network, referred to as CPN, or Subscriber Premises Network, referred to as SPN) refers to the interface between the user terminal in the customer premises area and the user-network (metropolitan area access network) interface. The machine line equipment is composed of the user resident wiring system that completes the communication and control functions, so that user terminals can be easily connected to the metropolitan area network. The scale of the resident access network varies greatly. It can be as large as a company, factory or university campus, as small as a small-scale residential area or even a residential buil...

AI Technical Summary

Problems solved by technology

[0012] As mentioned above, there are many problems in the traditional access network, especially the narrow frequency band and low spectrum utilization rate. It is impossible to achieve unified access to all information and communication networks in the 500kHz-3GHz frequency band, and it is impossible to build a unified resident access network.
