Embodiment Construction

[0019] In order to better understand the technical solutions of the present invention, the embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Embodiments of the present invention provide a wired broadband speed-up expansion system, such as figure 1 as shown,

[0021] A wired broadband speed-up expansion system, characterized in that,

[0022] Including a core switch 20, an IPQAM modulation device 21, an optical transmitter 22, an optical multiplexer 23, a data speed-up expansion device 24, and a terminal receiver 25;

[0023] The core switch 20 is connected to the Internet, and can receive the IP uplink data uploaded by the user's family through the IP network; the core switch 20 separates the IP data of the Internet into IP uplink data and IP downlink data, and the core switch 20 also The IP downlink data is grouped and subpackaged successively; then the IP downlink data packets that have b...

Abstract

The invention provides a data acceleration capacity expansion device. The data acceleration capacity expansion device comprises a light wave decomposition multiplexing module, a light receiving module, a tuning demodulation function module, a QAM modulation module, a central processing unit CPU module, a frequency mixing module and a radio frequency amplification module which are connected; the composite optical signal can be converted into the radio frequency signal and the radio frequency signal is transmitted to the terminal receiver, so that the data processing of the IP network is realized, the downlink bandwidth of the trunk line IP data output by the broadcast television HFC network in a front-end manner can be greatly improved, and the bandwidth can also be improved to a high speed of 100 megabytes.

Description

technical field [0001] The invention relates to a wired broadband speed-up and capacity expansion system, in particular to a data speed-up and capacity expansion device. Background technique [0002] Since its birth, the cable TV network has developed to today, and has provided high-quality TV broadcasting services to hundreds of millions of users after more than 40 years. However, with the rapid development of IP technology, the popularization of fiber-to-the-home, 4G technology and the arrival of the 5G era, the cable TV network has received an unprecedented huge impact. It is increasingly difficult for the one-way transmission service provided by the cable TV broadcasting network to meet the needs of the majority of users for video content. As early as more than 20 years ago, some cable TV operators began to try to use technologies such as Docsis to start two-way transformation of cable TV networks. Although they achieved some results, they barely maintained operations i...
