Shenzhen Dasheng OptoElectronic Technology Co., Ltd., a high- tech enterprise, founded in July 2000, is committed to R&D, manufacturing and application of highly innovative plastic optical fiber (POF), plastic optical cable and optoelectronic components and devices. With more than 15 years of experience in POF field, the company becomes one of the biggest plastic optical fiber makers in China. Since 2004, a lot have been invested to develop low attenuation PMMA POF for data communication. We succeeded in 2006 in achieving a low cost, a stable attenuation of less than 200 dB/Km at 650 nm wave length (typically at a level of 180 dB/Km) and 100 Mbps bandwidth over 100 meters distance. We are truly only one who can achieve an industrial production of low attenuation data communication PMMA optical fiber in China currently. Our innovative technology comes close to advanced international level but with a much lower production cost.
