Embodiment Construction
[0028] Such as Figure 1-5 As shown, a bent optical fiber array includes a bent clamp block 1, an optical fiber 2 and a microporous plate 3, and the microporous plate 3 is provided with positioning holes 4 arranged in sequence for passing through the optical fiber 2. The top and bottom of the bending clamp 1 are bent into a set angle. Generally, the set angle is set to 90°, but the set angle is not limited to 90°, and can also be adjusted within the range of 80-120° according to actual needs. The inside of the bending clamp block 1 has an accommodating cavity 5 for the optical fiber 2 to pass through. The bottom of the bending clamp block 1 is provided with a through hole 6 for the optical fiber 2 to pass through. The through hole 6 is arranged on the positioning hole 4 so that the optical fiber 2 penetrate the positioning hole 4, pass through the through hole 6, pass through the accommodating cavity 5, carry out bending, and then protrude from the top of the bending clamp 1, ...

The invention discloses a bent optical fiber array, and the bent optical fiber array comprises a bent clamping block, an optical fiber, and a micropore plate. The micropore plate is provided with positioning holes which are sequentially arranged and are used for the passing of optical fibers. The top and bottom of the bent clamping block are bent to certain angles, and the interior of the bent clamping block is provided with an accommodation cavity for the passing of the optical fibers. The optical fibers pass through the positioning holes and then pass through the through holes to be bent bythe accommodation cavity and finally extend out of the top of the bent clamping block. The top of the bent clamping block is provided with a groove for the placement of the optical fibers. According to the invention, the micropore plate is used for replacing a conventional V-shaped groove and a cover plate, so the thickness is smaller, and the bending of the optical fiber array in a smaller rangeis easier. The micropore plate achieves the overall positioning and fixing of the optical fibers, but the V-shaped groove and the cover plate perform the clamping of the optical fibers through combination, which causes the assembly error, and enables the reliability to be poorer than the overall fixing mode with the micropore plate. The structure employing the micropore plate and the bent clampingblock is simple in structure, is easy to assemble, and achieves the miniaturization for the implementation of an optical fiber bending function.
Description
technical field [0001] The invention relates to the field of optical fibers, in particular to a bent optical fiber array and a manufacturing method thereof. Background technique [0002] With the development of optical fiber communication technology, the application of optical fiber array is more and more extensive. A fiber optic array is a kind of fiber optic device in which multiple fibers are precisely arranged in parallel. Optical fiber arrays are usually used in connection with optical waveguide chips, micro-electromechanical systems (MEMS), and various integrated optical components. It is required to have high-precision optical fiber positioning, and the accuracy is required to reach the micron level. [0003] Usually, when the optical fiber array is coupled and docked with the optical chip, it is connected on the side of the chip. At this time, the optical fiber is straight in and out. For the coupling and docking of the optical fiber array, if the original straight...
