Abstract

The invention relates to an adaptation method for Ethernet signal transmission. The method comprises a signal amplitude amplifying step when the signal is transmitted between a coaxial-cable network and a twisted-pair Ethernet physical layer chip. The invention has the advantages that the adaptation method can farthest utilize the twisted-pair Ethernet physical layer chip to realize the transmission in the existing CATV coaxial network and realize the transmission suitable for the coaxial network fading characteristic in the existing CATV coaxial network.

Description

technical field [0001] The invention relates to an adaptation method and device for Ethernet signal transmission, in particular to an adaptation method and device for twisted pair Ethernet physical layer chip and coaxial cable Ethernet signal transmission. Background technique [0002] Convergence is the development trend of today's information and communication industry. Due to technical, historical reasons and business characteristics, in the world, the telecommunication network represented by the telephone network and the CATV network (Community Access Television or Cable Television, cable TV network) are divided according to the three major businesses of telecommunications, broadcasting and Internet The radio and television network represented by the Internet and the computer network represented by the Internet are independently designed, constructed and operated separately. Separate network construction, high construction costs, high operation and maintenance costs, is...
