Ethernet transmission method and Ethernet transmitting/receiving device based on coaxial cable network

Abstract

The invention relates to an ethernet tranceiving device on the basis of a coaxial cable network and a method for transmitting the Ethernet, the receiving device comprises an analog interface (110) which is connected with a coaxial cable, a voltage amplification unit (260) which is connected with the analog interface (110) and used to amplify sent signal electric levels of the analog interface (110), a receiving unit (200) which is connected with the analog interface (110), wherein the receiving unit (200) comprises a receiving and amplifying unit (210) which is used to amplify received signalelectric levels form the analog interface (110), wherein the magnification factors of the voltage amplification unit (260) and the receiving and amplifying unit (210) are confirmed by attenuation characteristics parameters of a coaxial cable distributing network. The method for transmitting comprises: amplifying service signals before sending services and amplifying the service signals on the direction of receiving the services. The invention can realize that baseband electrical signals of the ethernet are transmitted in a coaxial distributing network and the cost is low.

Description

Ethernet transceiver device and Ethernet transmission method based on coaxial cable network technical field The present invention relates to Ethernet physical layer transmission technology, in particular to an Ethernet transceiver device and an Ethernet transmission method based on a coaxial cable network; specifically, to an Ethernet transceiver device based on a cable television coaxial cable distribution network, and The physical layer transmission method of Ethernet over coaxial cable distribution network. Background technique In the existing cable TV fiber coaxial network (HFC), the TV program is transmitted from the front end to the optical node of the TV network close to the user through the optical fiber (generally, an optical node covers 300 to 500 users in the surrounding area). After the optical signal is converted into an electrical signal at the node, the TV signal is transmitted to each resident's home through the residential building through the coaxial cabl...
