Description

Fiber optic terminal box

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a photonic bandgap, and more particularly to a photonic bandgap in which an optical cable is connected or branched.

The data transmission method using optical fiber is widely used in the communication field because it is much superior in the transmission rate and the quality of the transmitted signal than the conventional method of transmitting data using the electric signal.

A general optical fiber has a disadvantage in that the transparent dielectric material such as quartz glass or plastic is made by elongating and pulling the dielectric material so that the strength of the material is relatively weak. For this reason, the outer surface of the optical fiber is covered with a buffer cover or the like to be formed into a cable shape.

When a part of the introduced optical fiber is connected to the optical fiber of the optical adapter and is distributed to the transmission device of the subscriber in the short distance, the optical fiber of the optical cable is in the form of an optical cable And is distributed to the transmission apparatus of the subscriber at a long distance.

Korean Utility Model Publication No. 20-2011-0005160 (published May 25, 2011. Hereinafter referred to as this document) describes a photonic band.

In the optical terminal box of this document, an inlet and an outlet are formed at one side of the body and the lid. The optical cable is drawn into the space portion of the main body from the outside through the inlet port or drawn out from the space portion of the main body through the outlet port. The space portion of the main body is provided with a fixing piece and a fixing member for fixing the optical cable to be drawn in or drawn out. Further, the space portion of the main body is provided with an optical adapter which is connected to the optical fiber in the optical cable and distributes to the subscriber side transmission device.

Such an optical adapter may be coupled to a tray. Here, the tray is rotatably coupled to the main body to divide the space for arranging the space of the optical cable and the space for the optical adapter.

At this time, under the optical adapter, another optical adapter capable of arranging the optical cable on the tray may be provided. These two optical adapters, stacked and mounted in a tray, can be coupled to the tray through respective couplings. And may be configured to be coupled to the tray through each of the engaging portions through one engaging member due to the laminated structure.

However, there is a problem in that the optical adapters that are stacked in this way must be separated from the optical adapter located above to replace the optical adapter located below. This is because each of the engaging portions is overlapped.

The second optical adapter unit 200 may be coupled to the tray 12 through the second coupling unit 210 in a state in which the second optical adapter unit 200 is stacked on the first optical adapter unit 100.

Since the second optical adapter unit 200 is stacked on the first optical adapter unit 100, when the first optical adapter unit 100 is coupled to the tray 12 through one coupling structure, The second optical adapter unit 200 must be separated first.

In the optical fiber cabinet 10 according to the preferred embodiment of the present invention, the first coupler 110 and the second coupler 210 are separately formed and arranged so as not to overlap each other, And the second optical adapter unit 200 are separated from each other or assembled in the tray 12 at different places.
