Communication coding system and method based on optical fibers and power lines

Abstract

The invention relates to a communication coding system and method based on optical fibers and power lines. The communication coding system includes an input interface module, a processing module, a power supply module, an output interface module, power line carrier interface equipment and a user terminal; the input interface module is used for receiving optical fiber signals and current signals transmitted by the optical fibers and the power lines respectively and sending the optical fiber signals and the current signals to the processing module; the processing module is used for processing the optical fiber signals and the current signals respectively, converting the processed optical fiber signals into electric signals, conducting hierarchical multiple coding on the electric signals and then loading the result electric signals to the power lines; the output interface module is used for transmitting the processed optical fiber signals and the electric signals to the power line carrier interface equipment through an external power line carrier equipment interface; the power line carrier interface equipment is used for transmitting the processed optical fiber signals and the current signals to the user terminal. A hierarchical multiple coding networking technology is adopted, a broadcasting storm is solved, and the situation that users do not interfere with one another on the Internet under the 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. Users can enjoy high-speed network access, browse the web, make VOIP calls and watch online TV and movies through TV at any socket with power outlets in the room, so as to realize the "multi-network integration" of data, voi...

Problems solved by technology

[0003] However, after practice, it is found that whether 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 used under high-speed broadband (above 20M). It solves the 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.
