[0040] Please refer to the following detailed description and accompanying drawings of this utility model. However, the accompanying drawings are provided for reference and illustration only and are not intended to limit this utility model.

[0041] Please see Figure 1 This is a plan view of an embodiment of the present invention. The present invention provides a one-to-many fiber optic cable structure and its connecting device. The one-to-many fiber optic connecting device includes the one-to-many fiber optic cable, a multi-core fiber optic connector 100, and multiple fiber optic connectors 110. The multi-core fiber optic connector 100 can be a multi-fiber push-on (MPO) or a multi-fiber pull-off (MPO) fiber optic connector, and each fiber optic connector 110 can be a fiber optic connector. The one-to-many fiber optic cable further includes multiple optical fiber cables 1, a sheathing component 2, and an adhesive structure 3.

[0042] Each optical fiber 1 includes a bundled section 10 and a branch section 11. One end of each optical fiber 1 is bundled into a single strip by its respective bundled section 10, while the opposite ends of each optical fiber 1 are separated into branch sections 11. Specifically, the bundled section 10 of the optical fiber 1 is bundled into a single strip by the aforementioned covering member 2. In one embodiment, the covering member 2 may be a heat shrink tubing, which is fitted to the length of the bundled section 10 of the optical fiber 1, thereby forming a single line segment by the covering member 2, and allowing the end of the bundled section 10 relative to the branch section 11 to be connected to the multi-core optical fiber connector 100.

[0043] As described above, the branch segments 11 of the plurality of optical fibers 1 can be independently connected to the aforementioned optical fiber connector 110 by each optical fiber 1.

[0044] Please refer to the following: Figures 1 to 3 As shown, the adhesive structure 3 is located at the junction of the bundled section 10 and the branch section 11 of the optical fiber 1. In one embodiment, the optical fiber 1 is fixed by adhesive bonding via the adhesive structure 3 and is covered by the sheathing member 2. Figure 2 and Figure 3 As shown, the adhesive structure 3 includes at least a first adhesive portion 30 bonded to the inner surface of the cover 2 and any two optical fibers 1, or further includes a second adhesive portion 31 bonded to the plurality of optical fibers 1. Here, the first adhesive portion 30 and / or the second adhesive portion 31 of the adhesive structure 3 can fill the gaps between the cover 2 and each optical fiber 1, thereby fixing the junction of the bundled section 10 and the branched section 11 of the plurality of optical fibers 1 with the adhesive structure 3. Thus, the branched section 11 of the plurality of optical fibers 1 can have a good bending effect due to the adhesive structure 3, while the bundled section 10 is well protected by the cover 2, and the cover 2 provides high-temperature resistance and other effects. In one embodiment, the adhesive structure 3 may be made of AV adhesive (ABS / PVC adhesive), but this invention is not limited to this.

[0045] Please see again Figure 1 As shown, in order to allow the bundled section 10 of the aforementioned optical fiber 1 to also bend appropriately, the adhesive structure 3 has a certain length range L on the bundled section 10 of the plurality of optical fiber 1, preferably falling within the range of 12mm to 15mm. In this way, while the optical fiber 1 is bundled at the junction of the bundled section 10 and the branch section 11, the branch section 11 of each optical fiber 1 is not easily damaged by separation due to bending, and at the same time, the bundled section 10 of each optical fiber 1 can also have a moderate bending effect.

[0046] Therefore, by means of the above-described structure, the one-to-many fiber optic cable structure and its connecting device of this utility model can be obtained.

[0047] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
