A one-fiber multi-network full-service access system

Abstract

The invention discloses a one-fiber multi-network full-service access system consisting of three layers of switches for dividing multiple virtual local area network (VLAN) configuration and communication among the VLANs, a local side, an optical distribution network (ODN) and a user terminal. One end of the three layers of switches is connected with IP telephone wires, wired cable television broadcast (CAVT) and network operators, and the other end is connected to the local side. The local side is connected to the user terminal via the ODN, the three layers of switches are gathered to connect a flow control server, and the local side is an optical line terminal (OLT). The ODN is composed of a single-mode fiber and a passive splitter, the user terminal is an optical network terminal (ONT), and the local side, the OND and the user terminal are connected via the fiber and are in single-core two-way transmission. With the arrangement of the three layers of switches, one fiber or one port of a client terminal can receive a plurality of signals including the internet, the television broadcast and the telephone, so that the network resource share can be realized, the low level repeated construction can be avoided, and a high-speed broadband multimedia foundation platform which is wide in adaptability and low in cost, and is easy to maintain is formed

Description

technical field [0001] The invention is an innovation to the application of network technology, relates to the technical field of regional network wiring, in particular to a one-fiber multi-network full-service access system. Background technique [0002] With the rapid development of high and new technologies such as global information networks and computers, communication technology has also undergone tremendous changes. At present, communication technologies such as Internet services and cable TV services have penetrated into every family. In the past, when users received the above services, operators such as China Mobile, China Unicom, China Telecom, and radio and television had to carry out wiring construction respectively. There were many shortcomings and limitations. Insufficient, specifically manifested in: ①. Each operator independently carries out wiring, resulting in low-level repeated construction and waste of resources; ②. Users are limited by wiring, price, and...

Problems solved by technology

At present, communication technologies such as Internet services and cable TV services have penetrated into every family. In the past, when users received the above services, operators such as China Mobile, China Unicom, China Telecom, and radio and television had to carry out wiring construction respectively. There were many shortcomings and limitations. Insufficient, specifically manifested in: ①. Each operator independently carries out wiring, resulting in low-level repeated construction and waste of resources; ②. Users are limited by wiring, price, and place of residence to passively choose network operation services; ③ , high cost, inconvenient maintenance
