Abstract

The invention discloses an interactive hybrid optical cascade matrix, which comprises a signal exchange module, an optical cascade module, a plurality of independent signal input modules and a plurality of independent signal output modules, wherein each signal input module comprises four mutually independent input interface conversion units, a first FPGA module and a Serdes sending unit; the firstFPGA module is provided with four first cache units, a packaging unit and four input video processing units; each signal output module comprises four mutually independent output interface conversionunits, a second FPGA module and a Serdes receiving unit, and the second FPGA module is provided with four second cache units, a video unpackaging unit and four output video processing units. A modularintegrated design is used, long-distance two-way transmission of multiple high-definition multimedia signals is achieved, the transmission distance is long, signal transmission is free of loss and time delay, and reliability is high.

Description

technical field [0001] The invention relates to an interactive mixed optical cascade matrix, which belongs to the technical field of satellite communication equipment. Background technique [0002] Today, with the increasing development of satellite communication technology, high-definition video signals can be transmitted through satellite channels. After the satellite ground station receives the high-definition video signal from the remote mobile station, there is a high-definition video access problem in how to connect with the conference high-definition video system. In the late 1980s, analog optical transceivers began to be used in China, and digital optical transceivers began to appear in 2001, demonstrating the process of economic development driving scientific and technological progress, and science and technology promoting economic development. With the advancement of science and technology, the cost of optical fiber production has been reduced, and optical fiber c...
