Embodiment Construction

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

[0020] The embodiment of the present invention provides a wired broadband speed-up and capacity expansion system, such as figure 1 shown,

[0021] A wired broadband speed-increasing and capacity-expanding system is characterized in that:

[0022] It includes a core switch 20, an IPQAM modulation device 21, an optical transmitter 22, an optical multiplexer 23, a data acceleration and capacity 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 home through the IP network; the core switch 20 separates the IP data of the Internet into IP uplink data and IP downlink data by uplink and downlink. The IP downlink data is successively grouped and subpackaged; th...

Abstract

The invention provides a data speed-up and capacity-expanding device, comprising: light wave decomposition and multiplexing module, light receiving module, tuning and demodulation function module, QAM modulation module, central processing unit CPU module, frequency mixing module, radio frequency amplification module connection, and through For the ability to convert the composite optical signal into a radio frequency signal and send it to the terminal receiver, so as to realize the data processing of the IP network, the downlink bandwidth of the backbone IP data output by the front-end output of the radio and television HFC network can be greatly improved, and the bandwidth can also be increased. Upgrade to a high speed of 100M.

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 for 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. The one-way transmission service provided by the cable television broadcasting network to users is more and more difficult 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 carry out two-way transformation of the cable TV network. Although some results were achieved, they were barely ab...
