하이브리드 인터커넥션을 위한 광전 복합 케이블 최적설계 및 특성에 관한 연구

Abstract

With the growing use of smart electronics such as PCs, TVs and smart phones commonly used in everyday life, the demand for continued growth in data and video signals, such as faster data processing speed and increased data storage capacity, is gradually increasing. Multimedia optical transport devices are devices that send high definition (HD) or full-definition video over long distances, and are used in large-area population density areas such as department stores, big marts, subways, and bus terminals. Due to the rapid development of the Internet, the use of HDMI is increasing as all information is being digitize due to demand for high capacity, high speed and high quality, and video transmission distances have increased in one location. EMI (Electro Magnetic Interference, Noise from Electromagnetic Interfaces) does not cause any distortion of data and, accordingly, transmission of display signals from medical devices or airplanes is possible. HDMI is expected to grow HDMI cables that require long-distance connectivity such as Home theater, Digital display system, and industrial/medical display system, and support high-quality images such as 1080p. It can gain competitive edge over products that are currently in use and occupy large markets not only in South Korea but also in other countries. HDMI, which is currently in commercial use, is mainly composed of three types: basic copper cable, copper optical fiber and GOF (glass optic fiber), hybrid cable with copper and POF (plastic optical fiber) have. POF Hybrid Cable has a disadvantage that it can not be transmitted over a long distance due to its large optical loss. Various attempts have been made to fabricate a GOF hybrid cable that combines a GOF and a copper. However, due to a sudden external change, GOF has a bending characteristic It is difficult to fabricate Hybrid Cable that combines GOF and Copper. The purpose of this study is to investigate the difference between the shape of the basic copper cable, which is the conventional HDMI cable, the shape of the copper and the GOF cable, and the shape of the hybrid cable using the combination of the copper and POF , The GOF hybrid cable that minimizes the optical loss by overcoming the GOF bending characteristic in the case where the GOF cable and the copper are separated from each other due to the large loss of light and the long distance loss was impossible) We want to design a fiber guide.
