BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of optical fiber communication networks, and more particularly to an optical fiber distribution set that is suitable for distribution of optical fibers distributed within a building to users. [Prior Art] 〇 10 In the field of modern telecommunications, optical fiber is widely used in the field of telecommunications, so the optical fiber distribution hub becomes a very important component in the optical fiber communication network. The fiber distribution hub provides an interface to the user, and the interface is connected between the trunk cable and the distribution cable through jumpers. However, due to the inherent properties of the fiber, various limitations on the fiber distribution hub are caused. For example, one of the most important limitations is the minimum bend radius that the fiber can withstand during use and storage. If the radius of the fiber being bent is less than the minimum bend radius of the fiber, the transmission performance of the fiber is reduced. For device reasons, 15 ❹ For fiber distribution hubs, care must be taken to ensure the minimum bend radius of the woven fabric. Due to the high density of the fibers, it is necessary to identify and obtain a single fiber or group of fibers for maintenance and redistribution, and the fiber-optic hubs that house the bundled fibers and connectors in the assembly have particular advantages. However, the fiber hubs that are common on the market today are bulky and inconvenient to disassemble and install.

And such an arrangement can be easily handled by 2009 200961. However, in the case, the connector can only engage the optical fiber from the optical splitter with the optical fiber entering from the outside, which cannot provide a heat-bonding connection and a mechanical connection. This type of folding box can only be used for existing taut line applications, and * can be used in applications where the light gauge is directly connected to the home. Therefore, the fiber distribution hub preferably provides fiber optic cable access, fiber optic cable retention, fiber storage, and the like, while the hub must accommodate one or more optical splitters. In addition, fiber distribution hubs need to provide as much as possible the area of fiber optic interconnection and the interface for fiber optic branching. SUMMARY OF THE INVENTION Accordingly, in accordance with an aspect of the present invention, a fiber distribution hub having a plurality of functions and being usable separately is provided, and a fiber distribution hub is convenient for field operation to reduce the time required for domain access and fiber connection. Further, the present invention provides a fiber distribution hub that realizes a compact and modular structure. Another object of the present invention is to provide a fiber distribution hub capable of having both a mechanical sleeve connection, a hot melt sleeve connection, and a connector connection in a single high density fiber distribution hub. In order to achieve the above object of the invention, the present invention provides a high density fiber distribution hub comprising a base housing, a beam splitter box, a connection tray and a cover, wherein the 'base housing includes at least one port portion' In the introduction, the button includes a first fiber, the beam splitter box is releasably connected to the base housing, and the connection tray is rotatably twisted to the base 6 200937061 The optical device can be engaged with the base housing to close the optical splitter A cassette and a connection tray, wherein the first fiber is connected to the second fiber in the connection tray, and the second fiber is connected to the beam splitter' to separate the plurality of signals onto the plurality of separate third fibers. 5 Ο 10 15 鲁 Other objects and advantages of the invention will be set forth in the description which follows, and some of the features will be apparent from the description and the invention.

In the exemplary embodiment of the present invention, the guide members 218 alternately alternately arrange the rod members in which the guide members 218 are "L" shaped equidistantly along the circumferential direction of the circular arc portion. And these l-shaped rods are disposed opposite each other to form a guiding passage ' that guides the optical fiber from the base casing 1 to the connecting tray 3 and makes it difficult for the optical fiber to be detached from the guiding member 218. 13 200937061 FIG. 4 is a plan view of the spectroscopic box 2. In the center of the splitter winter 2 shown in Fig. 4, a first holder 217 is provided between the coil members 208, 209 and the optical fiber guide 206, and the first holder 217 is for holding the fan-out portion 8. Generally, a plurality of optical fibers (for example, four, six, eight, twelve, etc.) are included in the ribbon fiber, so that the management of the optical fiber is performed. However, in use, the ribbon fiber needs to be divided into a plurality of individual fibers, and the plurality of individual fibers can then be terminated with the fiber connector. These connectors are then plugged into one side φ of the fiber optic connector adapter 9, which is placed in a slot 207 on the rear end 122 of the splitter box 2 (shown in Figure 8) to form a plug Board to provide end users with 10 fiber connections.

Further, a second holder 216 for holding the beam splitter 7 is disposed between the second receiving member 214 and the two second fiber winding members 208, 209. A splitter provides a special purpose connector that joins one fiber to two or more other fibers to form a branch connection. "The beamsplitters are usually relatively hard cells that must be protected against vibration and shock to ensure their 15 performance. At the same time, they are often kept in hubs, fiber optic boxes, etc., to the excess length of the fiber, and the extra fiber allows for maintenance or redistribution of the fiber after initial installation. In an embodiment of the present invention, by disposing the optical splitter 7 in the optical splitter box, one optical fiber can be divided into a plurality of optical fibers, thereby playing the two optical fibers in the optical fiber distribution hub 1〇〇. Very good management role.
