Title: The Innovations of Song Wang
Introduction
Song Wang is a notable inventor based in Hubei, China. He has made significant contributions to the field of optical fiber technology, holding a total of six patents. His work focuses on developing advanced multimode and single-mode optical fibers, which have applications in various temperature-measuring systems.
Latest Patents
One of Song Wang's latest patents is for a multimode optical fiber, which includes a core and a cladding covering the core. The core has a radius ranging from 23.75 to 26.25 micrometers. The refractive index profile of the core features a graded refractive index distribution with an index distribution index α between 1.80 and 1.89. The core also has a maximum relative refractive index difference Δ1% ranging from 1.0% to 1.15%. This multimode optical fiber exhibits a fusion loss of less than or equal to 0.08 dB and is utilized in a middle-and-long distance distributed temperature-measuring system, achieving a temperature-measuring distance of 10 km to 27 km. The system comprises a pulsed laser light source, a wavelength division multiplexer, an avalanche photodiode, a data acquisition device, an upper computer, and the temperature-measuring multimode optical fiber.
Another significant patent by Song Wang is for a bend-insensitive single-mode optical fiber. This fiber features a fused-biconical-taper design and includes a core made of fluorine-germanium co-doped silicon-dioxide quartz glass. The diameter of the core ranges from 7 to 10 micrometers, with a relative refractive index difference of 0.20% to 0.40%. The cladding consists of three layers, with the first layer being a fluorine-germanium co-doped silicon-dioxide quartz glass layer, the second layer a fluorine-doped silicon-dioxide quartz glass layer, and the third layer a pure silicon-dioxide quartz glass layer.
