摘要： An optical waveguide fiber comprises: (a) a core with a refractive index profile having, a radius, an alpha and a relative refractive index characterized by delta% that varies along the radius; (b) at least one cladding surrounding the core; wherein the alpha is less than 2.5, peak refractive index delta % is between 0.34% and 0.4%, the relative refractive index is less than 0.01% for all radii greater than 7 pm, and this optical waveguide fiber has a mode field diameter MFD at a wavelength of 1310 nm of no more than 9.54 μm, and attenuation less than: (a) 0.329 dB/km at a wavelength of 1310 nm, (b) 0.290 dB/km at a wavelength of 1383nm, (c) 0.255 dB/km at a wavelength of 1410 nm, and (d ) 0.189 dB/km at a wavelength of 1550 nm.

摘要： An improved method of making a larger map from individual 7.5 minute digital line graph (DLG) data is described herein. The process is fully automated and performed by a computer with minimal human interaction required. This eliminates errors and produces a more accurate final map product. The method includes conversion of the raw DLG data files into ARC/INFO format, locating the border arcs of each individual data set, edgematching the individual map data sets, and joining the data sets into a single, large map coverage. Any node along the border arc which cannot be automatically edgematched is noted in a special error file. A geographer then matches the unmatched edges which contain an error in the input data. A large map product is available as the product of the process.
摘要翻译：这里描述了从单独的7.5分钟数字线图（DLG）数据制作较大地图的改进方法。该过程是完全自动化的，并且由需要最少的人际交互的计算机执行。这消除了错误并产生了更准确的最终地图产品。该方法包括将原始DLG数据文件转换为ARC / INFO格式，定位每个单独数据集的边界弧，对各个地图数据集进行加工，并将数据集合连接成单个大型地图覆盖。在特殊的错误文件中记录了边界弧上不能自动修剪的任何节点。然后，地理学家将输入数据中包含错误的不匹配边匹配。作为该过程的产物，可提供大型地图产品。
