The present invention relates to an optical branching box for distributing and supplying an optical cable supplied from a telephone station to an optical facility to an optical facility by attaching it to a wall or a wall to construct an FTTH (Fiber To The Home) PON network, which is a next-generation optical subscriber network structure. By physically dividing the optical cable facility section and the optical outdoor construction section, it is possible to independently wire the optical fibers according to the purpose of operation, minimizing the operational errors in the construction work, and the optical cable facility section provides the optical cable supplied from the telephone company. By installing an optical cable (star cable) with a fan-out cord, passive optical device (splitter, AWG), or multi-core optical jumper cord in advance, the optical branch box is integrated to save the construction time during the field installation. It also relates to the light divergence to improve the quality of the.

In general, a conventional optical branch box is a structure in which an optical cable from a telephone company is introduced and the required optical fiber of the incoming optical cable is fusion-spliced with the optical jumper one-sided cord and then drawn out in the form of optical outdoor and optical cable through the optical adapter in the optical branch box. . Therefore, the incoming fiber cable from the telephone company, the connection between the optical fiber of the optical cable and the optical jumper one-piece cord, and the optical fiber trimming part should exist in the branch box, and it takes much time and skill of the operator to build it in the field.

In addition, it is difficult for a novice to perform the task of drawing out the necessary optical fiber from the connection tray, fusion splicing the extracted optical fiber, and fixing it again to the optical connection tray after the construction of the optical branch box facility. In addition, there are many difficulties in providing optical facilities to general dedicated optical subscribers, and a structure that protects the fusion splicing part, that is, more connection trays are required, and when the optical cable is supplied to the optical subscribers that occur frequently, Since the fusion splicing work is likely to affect other lines, the existing optical box has caused many difficulties in constructing the facility according to the structure and connection method.

The installation and connection parts (temporary parts) are physically divided on the right side, and are covered with an inner cover 13 connected by a hinge h2 at the upper and lower center portions of the base plate 12. Here, the inner cover 13 has an area corresponding to half of the area of the optical splitter box 1 so as to selectively cover the left side or the right side of the optical fiber storage and the connecting portion, so that the operator can install and branch the optical cable from the telephone company. The inner cover 13 is flipped to the right side as shown in FIG. 2 so that the influence of the work is not affected on the photo-outer rays on the right side, and the inner cover 13 is installed when the worker installs and connects the photo-outer rays supplied to the subscriber. As shown in FIG. 3, the operation of the optical cable and the optical fiber on the left side may be prevented from being flipped to the left side.

Referring to FIG. 2, the stop optical cable 6 is fixed to the optical cable inlet 21 provided at the lower left end of the optical branch box 1 by the optical cable tension line fixing part 23, and the front end of the stop optical cable 6 is provided. The optical fibers 61 branched from are wound up and down around the curvature holding guide 241 of the filter processing storage unit 24 so as to maintain an allowable radius of curvature of the optical fiber and arranged vertically in the central portion of the optical branch box 1. The connector 41 is connected to the adapter 41.
