As the development of communication technology, optical fiber communication is used widely. All kind of optical fiber terminals has been utilized. In this paper, a kind of optical fiber terminal has been introduced. The optical fiber terminal can be used in Tele- communication, mobile communication, power system, and so on. The functjon of the optical fiber terminal has been described in detail. We use single microcomputer in the device. The single microcomputer can control the optical transfer device. The alarm signal that the device has been occurred will been displayed. We can dispose of it in time. |
