Optical cable number management system and control method

The present invention relates to an optical cable number management system and a control method thereof, and more particularly, to an optical cable number management system and a control method capable of real-time or on-site collection and management of environmental information and optical cable number information inside a connection box of an optical cable. It is about.

In general, telecommunications and broadcast subscribers use data such as high-speed Internet through Asymmetric Digital Subscriber Line (ADSL), Very High Bit-Rate Digital Subscriber Line (VDSL), Ethernet Local Area Network (LAN), and cable modem. The service is being used, and cable service and satellite broadcasting based on HFC (Hybrid Fiber Coaxial) are used for broadcasting service.

In recent years, in order to provide high-speed, high-capacity communication and broadcasting services to subscribers, the popularity of FTTH (Fiber To The Home) systems connecting optical cables to subscribers' homes has been rapidly increasing.

Optical cable is a cable for transmitting optical signals, unlike general coaxial cables for transmitting electrical signals, it is possible to quickly transmit a large amount of information without loss, the demand of the optical cable is rapidly spread in accordance with the recent information age. Related technology development of optical cable is also steadily being made.

Such optical cable should be connected to the middle of the middle according to the installation length, wherein the optical cable is connected by using a separate connection terminal, even if the branch is made as much as necessary from the optical cable using the optical cable connection terminal Will diverge.

In the communication using such an optical cable, each optical fiber can be divided into several to accommodate subscribers. For example, a signal passing through one optical fiber is provided by using an optical passive element (optical splitter or wavelength splitter). Can be distributed as a signal.

Therefore, an optical cable connection distribution box has been proposed for connecting an optical cable including a plurality of optical fibers to a neighborhood of a home subscriber and connecting the optical fiber of the optical cable to a terminal of the indoor subscriber.
