The present invention relates to an outdoor housing for optical communication used in an optical transmission line for providing a high-speed communication service, and more particularly, an internal space of the enclosure is divided into independent spaces of a system unit and a subscriber wiring unit. It is very easy to connect and distribute the optical fiber by preventing the breakage of the optical fiber splitter and selectively withdrawing the optical fiber splitter to the outside, and it is possible to keep various cables neatly by using the cable support attached to the lower part. It is about enclosure.

In today's information society, the role of communication network is very important. Especially, as network communication such as the Internet is developed and a large amount of data is transmitted such as video or voice, an increase in information throughput and processing speed is required. The expansion of the network is urgently needed.

In order to satisfy this demand, an optical cable is used instead of a conventional coaxial cable in order to process a large amount of information at high speed, and the use of the optical cable is increasing rapidly.

In particular, as the use of optical communication networks is active, the use of optical subscriber network types such as FTCC (Fiber to the curb), FTTH (Fiber to the home), and FTTD (Fiber to the desk) has been increasing.

In general, in the construction of the optical communication network, since an optical cable is provided with a finite length, an apparatus for connecting an optical link between a telephone station and a subscriber's building or an optical subscriber is required. Are interconnected in the field.

In addition, in order for the optical fiber in the optical cable to be interconnected with the transmission device of the optical subscriber, the optical fiber must be distributed from the optical cable to the optical subscriber, and for this purpose, an outdoor enclosure for optical communication is installed on the building's building, exterior wall, or pole.

As an example of such an optical communication outdoor enclosure, a "patent application No. 2003-85047 name outdoor communication distribution apparatus cabinet" filed by the applicant of the present invention has been proposed.

In the present invention, the present invention includes a rectangular enclosure having a fixed panel for fixing an outdoor enclosure to an electric pole, and a cover that is selectively opened and closed by connecting the enclosure and the hinge, and the enclosure and the cover are fixed bands.
