Communication coding system and method based on optical fiber and power line

Abstract

The invention relates to a communication coding system and method based on an optical fiber and a power line. The communication coding system comprises an input interface module, a processing module,a power supply module, an output interface module, power line carrier interface equipment and a user side; the input interface module receives an optical fiber signal and a current signal which are transmitted by the optical fiber and the power line respectively and send the optical fiber signal and the current signal to the processing module; the processing module processes the optical fiber signal and the current signal, converts the processed optical fiber signal into an electric signal, conducts hierarchical multiple coding on the electric signal and then loads the electric signal to the power line; the output interface module transmits the processed optical fiber signal and current signal to the power line carrier interface equipment through an external power line carrier interface; and the power line carrier interface equipment transmits the processed optical fiber signal and current signal to the user side. According to the method, the networking technology of hierarchical multiple coding is adopted, the broadcast storm is solved, and the purpose that users do not intervene mutually when surfing the Internet under a high-speed broadband is achieved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication encoding system and method based on optical fiber and electric power line. Background technique [0002] In recent years, the power carrier technology combined with optical fiber and power line has become a brand new network access technology. Its advantages and characteristics are: 1) Using power line as the carrier, it provides the best home solution for high-speed broadband "last 100 meters" , PLC can transmit various data, voice and image, etc., and is generally applicable to networking and high-speed Internet access in residential quarters, institutions, schools and other places. Photoelectric broadband is flexible and easy to use. The user can use any socket with a power outlet in the room Access to PLC equipment , you will be able to enjoy high-speed network access, browse the web, make VOIP calls and watch online TV and movies on TV, so as to reali...

Problems solved by technology

[0003] However, after practice, it is found that no matter it is a residential building, a shopping mall, a hotel, an office building, etc., due to the problem of sharing the zero line in the wiring of the power system in our country, the power carrier technology combining optical fiber and power line is under high-speed broadband (above 20M). go online There is a problem of competing for bandwidth with each other, resulting in the widespread occurrence of broadcast storms

Broadcast storms not only exist in power carrier technology, but also in the GPON fiber-to-the-home technology of the four major operators. This drawback has always been a technical problem in the communication industry, and has always troubled operators and the majority of network users.
