Description

Technical Field

[0001] This utility model relates to the field of fine-tuning structure technology, and more specifically, to a fine-tuning structure for an optical fiber coupler. Background Technology

[0002] An optical fiber coupler, more commonly known as an optical fiber splitter, optical fiber combiner, or optical fiber distributor, is a passive optical device that distributes optical signals between two or more optical fibers. The working principle of an optical fiber coupler is based on the coupling effect of optical waveguides. In a coupler, two or more optical waveguides are so close that light waves can interfere and couple between them. By precisely controlling parameters such as the waveguide spacing, length, and refractive index, precise distribution of optical signals can be achieved.

[0003] Existing fiber optic couplers typically use multiple optical fibers to be fixed together with cable ties. However, this method lacks proper securing mechanisms. Furthermore, the fixed fibers are prone to damage during fixing and adjustment, making the coupler difficult to adjust and unsuitable for long-term use. Utility Model Content

[0036] Working principle: The placement seat 4 is set by the bottom fixing seat 1. The micro-adjustment protrusion 3 is rotated by manually rotating the bottom rotating shaft 2. The relative height of the placement seat 4 is adjusted and fixed by adjusting the external shape of the micro-adjustment protrusion 3. The placement seat 4 is used to set the fiber optic coupler body 8. The placement of the fiber optic coupler body 8 is positioned by the side limiting frame 5 and the side limiting frame 6. Then, the fiber optic coupler body 8 is fixed by the top fixing frame 9 and the top limiting plate 12. Then, the top fixing frame 9 is fixed by the long fixing bolt 10, which improves the installation and fixing effect of the fiber optic coupler body 8. The relative height of the fiber optic coupler body 8 can be finely adjusted by rotating the bottom rotating shaft 2.
