Low birefringence rotation fiber 
 Can be generated when the rotating glass fiber glass forming the light guide, such inconsistencies in the fiber dispersed in every possible direction, effective fiber light refraction completely eliminated. So that we get a polarized light through the fiber, and even has the same effect in the optical fiber is bent or twisted case. Compared to the traditional polarization maintaining fiber, either to maintain a linear polarized light and circularly polarized light can also maintain a very low error rate in the long-distance transmission, and does not require any special handling (such as high-temperature annealing). Rotating optical fiber can be adapted to a variety of application needs to rely on this particular performance. Pairs of high internal light refraction pre-forming and synthesis pressure (LB650, LB1300, and LB1500) or elliptical-core optical fiber LB1300 rotation fiber can be quite accurate in the case of bent and twisted to keep the light polarization. This avoids the high temperature annealing treatment. To maintain the accuracy of the polarization here only with internally generated pairs of light refraction caused by the error related with the length of the fiber. If you are using a conventional single-mode fiber, the fiber will not produce pairs of light refraction, the polarization can only be curved in a very short distance can be maintained. 

 PMD in spun fiber 
 Photoelectric sensors or remote communication, in general, low light refraction rotating optical fiber can significantly reduce polarization mode dispersion. LB1300 of polarization mode dispersion (Polarization mode dispersion) and only a tenth of the traditional communication optical fiber.
