FIG. 7 is an enlarged perspective view showing a state in which the optical fiber guide according to the present embodiment guides optical fibers. FIG.

2 to 7, the optical signal transmission apparatus 100 includes a main tube 10, an FTTH home terminal box 50, an optical fiber 20, a tension portion 40a, and a branch cable 30 do.

The main tube 10 has a predetermined length, and its length may vary depending on the height of the building. One side of the main tube 10 is disposed at the lowest position of the building and the other side is disposed at the highest position of the building. However, the positions of the one side and the other side of the main tube 10 can be mutually changed.

The inside of the main tube 10 is hollow along the longitudinal direction, and an opening 11 connecting the empty internal space to the outside is formed. A plurality of openings 11 are formed at intervals along the longitudinal direction of the main tube 10, and each of the openings 11 is located adjacent to each living space. The opening portion 11 is formed by cutting off the main tube 10. However, the opening 11 may be formed by cutting at least a part of the main tube 10.

A plurality of optical fibers 20 are formed and disposed inside the main tube 10 together with an aramid yarn (not shown). The number of optical fibers 20 may be the same as the number of living spaces.

The lengths of the optical fibers 20 are formed differently. One side of the optical fibers 20 is located on one side of the main tube 10 and exposed to the outside to be connected to the equipment of the communication room. However, when the communication room is located on the other side of the main tube 10, one side of the optical fibers 20 may be positioned on the other side of the main tube 10 and exposed to the outside.

The other side of the optical fibers 20 penetrates inside the main tube 10 and is exposed to the outside through the respective openings 11. The other side of the optical fiber 20 having the shortest length among the plurality of optical fibers 20 is adjacent to the opening 11 closest to one side of the main tube 10, And the other side is disposed adjacent to the open portion 11 located farthest from the one side of the main tube 10.

A coating layer (not shown) may be formed on the outer circumferential surface of the optical fiber 20 located in the main tube 10, and the coating layer may be made of acrylic. The coating layer protects the optical fibers 20 from external impact or the like. In general, the circulated optical fiber is protected by the cover, but the portion of the optical fiber 20 located in the main tube 10 according to the present embodiment is protected by only the coating layer.

If the optical fiber 20 located in the main tube 10 is covered with a covering, there is a problem that the diameter of the main tube 10 must be increased due to the thickness of the covering. However, in the case of this embodiment, the optical fibers 20 located within the main tube 10 are omitted, so that the diameter of the main tube 10 can be minimized by the diameter of the covering. However, the portion of the optical fiber 20 exposed to the outside of the main tube 10 is protected by the cover.

One side of the aramid yarn located in the main tube 10 is exposed to the outside of the main tube 10 through the opening 11. The side of the aramid yarn is passed through the coating protecting the other side of the optical fiber 20, Connected to the connector located.

Therefore, a detailed description of the structure of the branch cable 30 will be omitted. The branch cable 30 may be omitted.

On the other hand, when the current communication company A is used and the communication company B is changed to the communication company B, the branch cable 30 of the existing communication company A is cut off while the communication company B installs a new terminal device. When the cut branching cable 30 is formed integrally with the optical cable 20 provided on the outer wall, and the communication company B changes (re-opens) to the communication company A again, the communication company A performs the operation of extending the optical cable 20 . If the extension operation is not performed, the optical cable is shortened and the optical cable 20 installed on the outer wall can no longer be used.

However, since the FTTH private terminal box 50 connected to the optical cable 20 is provided on the outer wall as in the present embodiment, even when the communication company B cuts the branch cable 30, the communication company A newly connects the branch cable 30 When connecting to the FTTH house terminal box (50), the optical cable installed on the outer wall can be continuously used. Therefore, the cost of installing the optical cable can be minimized.
