*** 9632052 Walker This STTR Phase I project will demonstrate the feasibility of a continuous process of producing rugged, low moisture content, high bandwidth, gradient index plastic optical fiber. Existing Japanese production methods result in bandwidths which are three to ten times less than theoretically possible, and the bandwidth of the fiber is not stable and reproducible. The production rate is intrinsically limited by the batch nature of the process and, or, multi-step procedure. In the United States, the High-Speed Plastic Network (HSPN) consortium was formed in 1994, and is supported by a $5 million Advanced Research Projects Agency grant. A member of that team has licensed one of the Japanese batch technologies to fabricate the above type of fiber. This project will develop a novel, low cost, continous production process for the fiber. The fiber will have a stable bandwidth of 2 GHz.km, be stable from -40 C to + 150 C, have low moisture uptake, attenuation of less than 150dB/kilometer and be stable to radiation exposure up to 1000 Rad. This type of fiber is expected to have great utility in high speed local area networks. Local area networks have inadequate band width for the anticipated needs in the coming years. Gradient index plastic optical fiber will be the most cost effective solution with adequate band-width. At present there is no satisfactory production process for a rugged version of this fiber. ***

*** 9632052 Walker STTR 第一阶段项目将展示连续生产坚固、低水分含量、高带宽、梯度折射率塑料光纤的可行性。日本现有的生产方法导致的带宽比理论上可能的带宽低三到十倍，并且光纤的带宽不稳定且不可再现。生产率本质上受到工艺的批量性质和/或多步骤程序的限制。在美国，高速塑料网络 (HSPN) 联盟成立于 1994 年，并得到高级研究项目局 500 万美元的资助。 该团队的一名成员已获得日本批量技术之一的许可来制造上述类型的纤维。该项目将开发一种新颖、低成本、连续的纤维生产工艺。 该光纤具有 2 GHz.km 的稳定带宽，在 -40°C 至 +150°C 范围内保持稳定，吸湿率低，衰减小于 150dB/km，并且在高达 1000 Rad 的辐射暴露下保持稳定。 这种类型的光纤有望在高速局域网中具有巨大的用途。局域网的带宽不足以满足未来几年的预期需求。梯度折射率塑料光纤将是具有足够带宽的最具成本效益的解决方案。目前，这种光纤的坚固版本还没有令人满意的生产工艺。 ***
