광케이블 선로를 위한 안정화 광원개발

Abstract

This study focuses on the realization of Fiber-Optic network's stabilization light source which is increasingly necessary according to the construction of the current high speed communication network. The stabilization light source is being used as an optical source in constructing the various Fiber-Optic networks,and developing the communication parts. And the light source consists of LED(light emitting diode) and Laser(light amplification by stimulated emission of radiation). LED has some merits, which are cheap and easy to treat, however the output is comparably small. And LED has some restrictions for transmitting the long distance because of broad line width. However, Laser, which has narrow line width and high output, is being used for transmitting the long distance and for the various LED and systems. This study develops the light source using Laser which is essential for the construction of communication networks as well as for the production and inspection of the communication parts. Considering for the portable,the stabilization light source, is developed light and easy to use, which has a structure using a small battery. As a result of an evaluation for the developed parts this study comes to know that an outstanding characteristic was realized because an accidental error occurred within ±0.1[dB] not only in the characteristic of the initial motion but also in the 10 hour long operation. built-in.
