With the increasing use of smart electronic devices, the size of the related I/O interface market is increasing rapidly. Demand is also growing for the continuous increase of data and video signals-such as faster data processing speed and data storage capacity-in the smart electronic device input/output interface market. Currently, the POF hybrid cable used in the smart electronic device input / output interface market cannot transmit over a long distance because the optical loss is too large, and the GOF hybrid cable is both vulnerable to bending and other sudden outside changes, and expensive. Therefore, in this study, the design and fabrication of a GOF hybrid cable and fiber guide were carried out in order to develop a cable which can easily withstand external impact, has low optical losses, and meets the demand for continuous data and video signal increase in the smart electronic device input / output interface market.

This study is aimed at suggesting optical communication equipment that can deliver high quality video information in high speed, to efficiently handle the flood and water pollution in the river basin. This system is cheaper than existing equipment, and can monitor optical Internet as well as the condition of equipment. Generally, the communication equipment to prevent flood is installed in an unmanned control box and operated by the flood control office situated at the fiver mouth in a long distance section. Therefore, it is hard to promptly cope with communication interruptions, which occur by the cutting or aging of the optical cable. Under the circumstances, this study suggested an efficient system that can deliver high quality video information in high speed (Optical Transmission Convert System) by using optical fiber. The system also solves problems by making use of automatic protection switching (APS) when an accident happens. Its real-time monitoring function gives notice of the problem-occurring points. The system is expected to be widely used in various areas such as intelligent traffic systems.
