The present invention relates to a ground light intermediary switch, and more particularly, it is convenient to handle and connect and expand an incoming and outgoing optical cable, and thus, it is possible to efficiently manage the optical cable, and to use a combination of a loose tube type and a ribbon type optical fiber. It is about a ground light changeover.

With the rapid development of the information and telecommunications field, there is a great demand for high-speed telecommunication facilities focused on subscriber networks, and for this purpose, ground fiber intermediates can be efficiently distributed and switched between the feeder fiber cable from the telephone station and the distribution fiber cable to subscribers on the optical cable line. The change box is installed.

In addition, the ground fiber intermediate switch box is provided with a connection tray inside the enclosure to perform the function of selectively distributing and transferring the incoming and outgoing optical cables. A loose tube type and a ribbon type multi-core optical cable are used. As the core of optical fiber is required, loose tube type single fiber is being replaced with ribbon type multi-core fiber cable.

FIG. 1 illustrates a conventional ground optical switching box, and a plurality of optical cable entry and exit pipes 2 are provided in a row on the bottom surface of the enclosure 1, and the frame 3 inside the enclosure 1 Both sides of the shelf 4 are fixed, and a plurality of connection trays 5 are provided in the shelf 4 so as to be movable back and forth along the rail.

In addition, the connection tray 5 includes first and second cable guides 6 and 7 for guiding the optical cable introduced through the optical cable inlet pipe 2, and a mandrel 8 which is dressed in a state where the optical cable is wound several times. It is installed.

The conventional ground fiber intermediate box configured as described above is a state in which the optical cable introduced through the optical cable inlet pipe (2) is aligned through the first cable guide (6) and the second cable guide (7) provided in the connection tray (5). In the state in which the incoming optical cable is wound several times on the outer circumferential surface of the mandrel (8), and the plurality of adapters (10) installed on the front of the panel (9) by drawing out a plurality of connecting cables from the end of the inlet cable supported on the mandrel (8) Are connected to the connectors 11.

However, the conventional ground light switching box configured as described above pulls the connection tray 5 forward in order to check the connection state of the connector 11 or to perform maintenance work thereof in the mounted state as described above. In the case of drawing out, since the pulling force is applied to the optical cable by the first cable guide 6, there is a problem that the optical cable is damaged.

Therefore, in order to solve such a problem, before arranging the optical cable introduced through the optical cable inlet pipe (2) to the first cable guide (6) in a state to secure a portion corresponding to the moving distance of the connection tray (5) with a margin The incoming optical cable should be aligned with the first cable guide 6, in which case the optical cable secured as a spare is placed in a slack state inside the enclosure, causing interference with the connection tray 5 which is opened and closed. There has been a problem that the optical cable stretched by the connection tray 5 is damaged.

In the conventional ground fiber intermediate transfer box, since the optical cable introduced through the inlet pipe 2 is aligned with the first cable guide 6 formed in the connection tray 5, the allowable curvature of the optical cable in this portion. There is a problem in that it is difficult to maintain the radius, and there is a problem in that the connection tray can be used only for a loose tube type single core optical cable and cannot be used in combination with a ribbon type multi core optical cable.

The present invention is to solve the conventional problems as described above, it is convenient to handle the insertion and extraction of the optical cable and the connection and expansion work, it is possible to efficiently manage the optical cable, can be used in combination with the loose tube type and ribbon type optical cable Its purpose is to provide intermediate ground light transfer.
