Germanium doped gradient fiber Pre-rods is Including UV (UV), VIS (visible light), NIR (near-IR), IR (IR) and other optical fibers with different wavelength range.A prefabricated material that can be used to pull an optical fiber. Optical fiber prefabricated rod is the core raw material for the manufacture of quartz series optical fiber.Large-core preform is a kind of preform specially designed and developed for the field of energy transmission and sensing. This series of preforms are prepared by in-tube chemical vapor deposition process, which has the advantages of high numerical aperture and good geometric uniformity. This series of products are widely used in laser energy transmission, data communication and other energy transmission, sensing and other fields.

Product Application
1. Optical fibers made from special wavelength optical fiber preforms can used for long-distance communications. Because optical signals of specific wavelengths have lower attenuation and higher stability when transmitted in optical fibers. It can ensure the quality and efficiency of information during transmission.
2. The optical fiber produced by it also suitable for erbium-doped fiber amplifiers (EDFA), etc. By doping specific rare earth elements (such as erbium). The optical fiber has a gain effect at a specific wavelength, thereby amplifying the optical signal and improving the transmission capacity of the communication system.
3. Optical fibers made from special wavelength optical fiber preforms can be used in medical instruments;
4. By doping or changing the material composition of the optical fiber, optical fiber sensors that are sensitive to biomolecules or bioprocesses can be made. Used to monitor physiological parameters or environmental changes in organisms in real time.
5. Optical fibers made from special wavelength optical fiber preforms can be used in laser ranging systems, which calculate the distance of the target object by emitting laser signals of specific wavelengths and receiving the reflected signalse
