Embodiment Construction

[0025] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. First, combine Figure 2-5 A first embodiment of the present invention will be described. Figure 5 The finished product of the optical wavelength reflector 10 according to the first embodiment of the present invention is schematically shown. Figure 2 ~ Figure 4 Various stages in the manufacturing process of the optical wavelength reflector 10 are shown. As shown in the figure, the optical wavelength reflector 10 mainly includes a first optical fiber 1, a first optical fiber built-in groove (V-shaped) 2, a second optical fiber 6, a second optical fiber built-in groove (V-shaped) 5, a multilayer optical coating layer and package structure. Such as figure 2 and image 3 As shown, the end face of the first optical fiber 1 and the end face of the first optical fiber built-in groove 2 are polished to a slope with a first inclination angle (for example, 0-1...

Description

technical field [0001] The invention relates to optical fiber manufacturing technology, in particular to an optical wavelength reflector and a manufacturing method thereof. Background technique [0002] When the fiber-to-the-home network detects fiber optic faults, it needs to use an embedded optical wavelength reflector. This optical wavelength reflector is installed in the fiber path at the end of the optical fiber network and can reflect the signal of the fault detection wavelength. The working wavelength can Pass with very little loss (such as less than 1.5dB). At present, most of these reflectors are manufactured based on fiber grating technology, which is costly, and the reflection bandwidth will also drift with the change of temperature. Contents of the invention [0003] Aiming at many deficiencies in the prior art, the present invention aims to provide a low-cost optical fiber path embedded reflector to meet practical application requirements such as fiber fault ...
