Description of the Invention: - Technical Field of the Invention [0001] The present invention relates to a dispersion compensator, and more particularly to an adjustable dispersion compensator for adjusting the amount and range of dispersion compensation. [Prior Art] [0002] In optical fiber passive components, the optical characteristics of a Chirp Fiber Bragg grating (CFBG) can be used as a dispersion compensator. However, the phase-graded fiber grating that has been written has its 0 dispersion compensation amount and compensation range fixed. Therefore, if you want to compensate for different degrees of dispersion signal, it is necessary to prepare a variety of dispersion compensation amount of light fiber grating for use, which not only increases the use cost of the dispersion compensator, but also reduces the convenience of the dispersion compensator. . Moreover, because the optical signals transmitted in the optical fiber communication system are affected by different degrees of dispersion through different distances, the fixed dispersion compensator with fixed dispersion compensation and dispersion compensation range will not fully satisfy the optical fiber communication system. Therefore, a dispersion compensator with a dispersion compensation amount Q can be adjusted to compensate the dispersion fiber number in the optical fiber communication system. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned lack of fiber dispersion compensator, the object of the present invention is to provide a tunable fiber grating dispersion compensator comprising an adjustment structure frame and at least one fiber grating, after adjusting the angle of the structural frame The change makes the adjustable fiber grating dispersion compensator compensate for different degrees of dispersion signal. At the same time, we hope to make a smaller size adjustable dispersion compensator with a simpler structure. 099107399 Form No. A0I01 Page 3 / Total 10 Pages 0992013350-0 201131221 The present invention - the implementation aspect is that the center wavelength can be controlled under a slight drift when performing bandwidth extension - in another embodiment, the control center is completed The wavelength can drift to any band that you want to compensate. [Embodiment] [0004] * Month, as shown in Figures 1 to 2, is a preferred embodiment of the adjustable fiber grating dispersion compensator of the present invention. The fiber grating dispersion disperser of the present invention comprises - an adjustment structure frame (1) And - fiber grating package components (7). The ten-adjusting structural frame (1) is a flat-shaped quadrilateral structure formed by combining four long strips ((1) two ends and two ends. The β angle of the structure is 〇. The longest two ends are respectively the first fixed end. (12) and the second fixed end (13) having a raised first fixing piece ((4) on the second fixed end (1)) and a raised second fixing piece on the 帛m疋 end (! 2) (15), using the raised first and second plates (14, 15) to fix the fiber grating package component (2) to adjust the structural frame (1). The fiber grating package component (2), comprising at least - The optical fiber bridge (2) is attached to the flexible substrate (22) by using a glue flat, and the two ends of the optical fiber package (1) have a first corresponding fixed end (23) and a second corresponding fixed end (24) The first and second fixing pieces (1)' 15) which are convex on the adjusting structural frame (1) are respectively fixed to the first fixed end (12) and the second fixed end (13) of the adjusting structural frame (1). By adjusting the structural frame (1) (4) angular angle change, the fiber grating package component (2) on it generates an S-shaped bend, which can cause the internal fiber cycle of the fiber grating (7) attached thereto to be formed - a gradual change Arrangement, this - gradual periodic arrangement is like a general cycle-graded fiber-optic first grating (21)-like, by the bowing mechanism of 099107399:, the invention can realize the periodic gradation of the fiber optic light (21) to the dispersion Compensation effect form number of the signal _ Page 4 / Total 10 pages Use the angle angle 099201c 201131221 change to adjust the compensation range of the adjustable dispersion compensator ° and the period gradient Ο ^ ^ The periodic arrangement of the gradient after the 3-shaped bending Let the original spectrum of the fiber optic surface (21) be at the original center wavelength...
