For the optical properties of optical fiber aligner, how much do you know

fiber alignment machine is used for light and detection of various optical devices for optical fiber in the aligner property is what kind of, is to introduce the fiber in optical fiber specification aligner, the specific content of the optical fiber cable and attribute to the use of optical fiber alignment has had a very good help.
1) Fiber properties ( 纤维属性) The relevant indicators, are the intrinsic characteristics of optical fiber. The geometric parameters such as fiber, mode field diameter macro bending loss, dispersion coefficient etc. These performance entirely by the geometric structure of the fiber and optical structure. The distribution of refractive index profile, not affected by cable mood structure and installation condition. About the cutoff wavelength, the theory of the fiber cutoff wavelength is also within few feature of optical fiber, generic cabling now the cutoff wavelength of the fiber, also known as the effective cutoff wavelength while related to state and laying optical cable structure, but, no matter from the numerical relation between the establishment of or equivalent method are put into line the cutoff wavelength of the fiber and the theory of the fiber cut check between wavelength has a very good sex. So it is classified as fiber properties.

2) Fiber Cable corner sex Attributes) Indicators related to the process of the first is by fiber properties in Beijing, but are greatly influenced by the state and laying optical cable structure, such as optical fiber attenuation index due to macro bending in the fiber optic cable junction tree, especially the influence of microbend fiber will generate additional loss, such as fiber coloring layer in uneven, optical fiber loose casing yu long improper control, etc. , all can lead to fiber optic microbend losses, after the cable laying long-term use process, also due to the deterioration of oil of optical fiber hydrogen loss factors lead to the increase of the fiber loss. More complex optical fiber polarization mode dispersion PMD first is due to the formation of geometric optical fiber itself or generated by the structure of the optical anisotropy of the results of the refraction of purveyance with optical fiber in optical capture by external mechanical forces, such as bending, twisting the horizontal pressure produced by the additional birefringence on not only that, when the cable laying in use process, also will be affected by environmental conditions, such as temperature varies. And this single external factors are suspended randomly changes as a result, the optical fiber PMD indicators, both before and after, before, during, and after cabling and fiber optic cable laying. So PMD coefficient in the maximum number of rules in the fiber properties, for certain hook must 攴 hold the light in the basic requirements of fiber optic cable link when using PM. Because of this, index of PMD in fiber properties, optical system sex, respectively, and shall have the statistical correlation.
