Abstract

Disclosed is a frequency mixing system, comprising: an uplink module, a data module for Ethernet over Coax under Data over Cable Service Interface Specifications (DOCSIS EOC), and a frequency mixing device. Further disclosed are the frequency mixing device and a frequency mixing method. By adopting the present invention, the problem that the performance of a head end apparatus such as a load capacity and a transmission distance accordingly degrades after multiple cable TV (CATV) radio frequency signals and DOCSIS radio frequency signals are mixed is solved, the load capacity and the transmission distance of the head end apparatus are improved, and at the same time a signal reception strength standard of a terminal apparatus such as a cable modem (CM), a set top box (STB), and a cable TV on a user terminal network side is met.

Description

technical field [0001] The present invention relates to the communication field, in particular to a frequency mixing system, a frequency mixing device and a frequency mixing method. Background technique [0002] In order to meet the requirements of providing multiple services such as video, voice, and broadband on the same home copper cable, various coaxial cable transmission Ethernet data (EOC, Ethernet Over Cable) technologies have emerged one after another. Among them, the passive optical network ( PON, Passive Optical Network) + Data Over Cable Service Interface Specification (DOCSIS, Data Over Cable Service Interface Specification) EOC technology is one of the main access solutions recommended by the State Administration of Radio, Film and Television, and has received widespread attention and application. However, to implement simultaneous transmission of DOCSIS services and CATV (Community Antenna TeleVision) services on the home copper cable, it is necessary to mix an...
