As shown in the figure, the optical distribution panel is connected to the upper and lower racks (1d, 1e), the left and right racks (1c, 1b), and the intermediate rack (1a) that equally divides the interval between the left and right racks (1c, 1b) to a predetermined size. The rack 1 is provided with a frame.

A shelf layer of a predetermined size is mounted in the space between the intermediate rack column 1a and the right rack column 1b, and the shelf 2 includes at least one optical fiber protective support plate 3 for mounting an optical fiber on the external subscriber side. ) Is mounted so that the optical fiber protective support plate 3 has a floating hole 3a formed at one corner thereof, and is mounted on one surface of the shelf 2 in a form of opening to be used for connection, tangency, and wiring of the optical fiber. , Take out only the optical fiber protective support plate (3) to perform a smooth operation.

Here, the fiber-optic protective support plate 3 is mounted on one surface of the shelf 2 so as to rotate on the surface of the plurality of shelves 2 connected to one side of the intermediate rack column 1a in order to facilitate storage and detachment. A support 4 having a shape is provided to be fastened by a screw 16, and one side edge of the optical fiber protective support plate 3 is fitted to the support 4, and the support 4 is illustrated in FIG. 5. As described above, holes 4b having a predetermined size are formed on one side of the upper and lower sides thereof, and the hinge shaft 5 is fitted into the hole 4b.

Therefore, one side corner portion in which the flow hole 3a of the optical fiber protective support plate 3 is formed is inserted into the intermediate receiving groove 4a of the support 4, but the hole of the flow hole 3a and the support 4 is inserted. After matching (4b), the optical fiber protective support plate 3 is easily rotated about the hinge shaft 5 while being coupled to the hinge shaft 5 to be easily stored and detached from the shelf 2.

At this time, the hinge shaft (5) is formed in a half-moon shape chamfered by a predetermined size in the longitudinal direction so that the optical fiber protective support plate (3) is rotated by a predetermined angle around the hinge shaft (5), when rotated by 105 ° Desorption was easy.

On the other hand, a loose-tube inlet 7 is formed on the upper side of the right rack circumference 1b to allow the optical fiber coming from the external subscriber side to be inserted into the optical fiber protective support plate 3.

Further, the optical jumper cord guide piece 6 is perpendicular to the number of the optical fiber protective support plates 3 at a predetermined position on one surface of the intermediate rack column 1a connected to the surface of the shelf 2 on which the support 4 is mounted. When connecting the optical fiber which is installed in the optical fiber protective support plate 3 and the indoor fiber optical fiber of the system side, the path of the optical jumper code drawn from the subscriber optical fiber and the indoor fiber optical fiber is guided.

A cable panel 8 is mounted on the upper surface of one side of the intermediate rack column 1a so that the indoor fiber optic fiber of the system side is connected, and the optical cable guide 9 provided in the cable panel 8 is horizontally on both sides thereof. Guide holes 9a of a predetermined size are formed so as to penetrate and guide the optical fibers coming from the system side to one line.

In addition, the optical cable holder (10) formed so that a plurality of holes 10a on one side thereof penetrate between the left end rack (1c) and the intermediate rack (1a) in order to fix the guided lined optical fiber of the optical cable guide (9). ) Is mounted up and down at predetermined intervals so that the optical fiber can be bundled and fixed through the hole 10a.

A plurality of jumper cord guide pieces 11 are mounted on the front side of the optical cable holder 10 at predetermined intervals up and down, and are positioned in the longitudinal direction to guide the optical fiber hanged on the optical cable guide 9 to be described later. To be connected to the connector 12.

One side of the jumper cord guide piece 11 is equipped with a slide guide 13 provided in a direction perpendicular to its position, the slide guide 13 is formed with a slide groove (13b) on the left and right sides thereof, the connector at the top The connector holder 13a of a predetermined size is formed to penetrate so that the 12 is detachable.

In addition, the slide guide 13 is provided on one side of the left rack column (1c), it is stored in the storage case 14 formed with a rail (14a) with a predetermined interval at the lower end.

Therefore, the slide groove (13b) formed in the slide guide 13 to slide and ride on the rail (14a) formed on the lower end of the storage case 14 so that the optical fiber is stored in the indoor optical fiber of the system (12) is easily taken out whenever necessary so that it can be connected to the optical fiber of the optical fiber protective support plate (3).

At a predetermined position of the upper rack column (1d) constituting the upper skeleton of the optical distribution panel, a fluorescent lamp can be installed to adjust the lighting of the optical distribution panel, and also the wheel 15 on the lower side to simplify the movement of the optical distribution panel. Was equipped.

Therefore, when looking at the operating state of the optical distribution panel of the present invention configured as described above, the optical fiber protection guide plate (3) mounted on the shelf (2) subscriber side optical fiber coming into the rack (1) through the loose tube inlet (7) Dress up in.

Then, the bundle of optical fibers coming from the system side is connected to the cable panel 8, wherein the optical fibers of the bundle are guided by the optical cable guide 9 and the foldable cord guide piece 11 to open the holes of the optical cable holder 10 Stringing through 10a) facilitates fiber processing of the wings.

In addition, the system-side indoor optical fiber connected to the cable panel 8 is guided through the optical jumper cord guide piece 6 and connected to the optical connector 12 mounted on each slide guide 13.

In this way, when connecting the external subscriber side optical fiber which is processed and drawn out to the optical fiber protective support plate 3 and the system side optical fiber, the slide case 13 with the plurality of optical connectors 12 is withdrawn from the storage case 14, And the optical connector 12 connected to the indoor fiber of the subscriber side is connected, and the optical fiber protective support plate 3 rotates about the hinge side 5 from the shelf 2 to be separated and rotated away. It is easy to connect the optical connector.

Therefore, it is possible to arrange the line quickly according to the change of subscriber beam in one optical distribution panel or service request, and to use the optical connector to which the indoor line of the system is connected easily. The loose tube can be properly introduced into the fiber optic protective plate, the shelf can be separated and used, and the abnormality of the line can be investigated without disturbing the call, thereby increasing work efficiency.
