Abstract

The invention discloses a system and a method for improving the data service bandwidth of a cable television network. The system comprises head-end equipment, modulation equipment and terminal equipment, wherein the head-end equipment comprises Ethernet over Coax (EoC) head-end equipment which is used for providing a first sending channel for sending a first data packet of service data; the modulation equipment is used for providing a second sending channel for sending a second data packet of the service data; and the terminal equipment comprises EoC terminal equipment which is used for providing two receiving channels for receiving the first data packet and the second packet of the service data respectively. By the invention, the problem of limited channel expansion capacity caused by relatively low EoC bandwidth and relatively few available channels is solved, and the data service bandwidth of the cable television network can be improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a system and method for improving the data service bandwidth of a cable TV network. Background technique [0002] In the process of two-way transformation on the cable TV network, EOC (Ethernet over Coax) is one of the most popular technologies at present, that is, to transmit Ethernet data signals in coaxial cables, and the mainstream is to modulate the Ethernet signals Data transmission is carried out in the coaxial cable, and its frequency does not occupy the cable TV frequency segment, and coexists with the cable TV frequency. It has the advantages of simplicity, stability, safety, and low cost. [0003] At present, there is no effective solution to the problem of limited channel expansion capability due to the low EoC bandwidth and few available channels in related technologies. Contents of the invention [0004] Aiming at the problem of limited channel expansion capability due...
