Latest Patents
One of his latest patents is titled "Dispersion-shifted single-mode fiber having low dispersion slope for large capacity transmission." This invention relates to a low dispersion slope dispersion-shifted single-mode fiber designed for large capacity transmission. The fiber features a core with three to five segments that have varying refractive index profiles, and a cladding with four to six segments. Notably, the total dispersion slope of this fiber at 1550 nm is less than 0.060 ps/nm·km, with a zero dispersion wavelength of less than 1420 nm. The effective area ranges from 55 μm to 65 μm, and the dispersion in the region of 1530 nm to 1565 nm ranges from 5.0 ps/nm·km to 12.0 ps/nm·km. This fiber is characterized by low dispersion slope, moderate dispersion, low attenuation, and excellent bend resistance performance, making it suitable for high-speed (10 Gbits/s and 40 Gbits/s), large capacity, and long-distance DWDM systems.
Another significant patent is "High performance dispersion compensating optical fibers and manufacturing method for the same." This invention provides a high-performance dispersion compensating optical fiber that includes a core layer and a cladding layer. The core layer consists of five core sublayers, with specific percentages of positive and negative refractive indices. The cladding layer is made of pure Silicon Dioxide glass, enhancing the fiber's performance in various applications.
