摘要： An optical fiber cable connector includes a ferrule with a guide hole that is shaped to closely receive a multicore fiber having a flat side indicative of the rotational orientation of the cores of the multicore fiber. The ferrule includes a flat surface at one side of the guide hole, corresponding in position to the flat side of the multicore fiber. Installing the multicore fiber into the guide hole with its flat side abutting the flat surface along the side of the guide hole provides alignment of the cores with respect to an optical component to which the multicore fiber endface is to be connected.

摘要： A laser cleaving apparatus for use in terminating optical fiber cable ends has a laser beam source, the output of which is directed through a beam distorting member, which produces a beam having a chisel shape with a substantially flat side normal to the axis of a connector fiber containing ferrule and focuses it onto the fiber at a point adjacent the ferrule end face with the flat side also adjacent the end face. A single step polishing stage polishes the cleaved fiber end face to make it flat and flush with the ferrule end face.

摘要： Optical fiber refractive index profile designs having an alpha core profile and a negative index trench to control bend loss, are modified by truncating the edge of the alpha core profile and adding a ledge to the truncated core. The result is low bend loss and preservation of low differential mode delay and high bandwidth.

摘要： The specification describes multimode optical fibers with specific design parameters, i.e., controlled refractive index design ratios and dimensions, which render the optical fibers largely immune to moderately severe bends. The modal structure in the optical fibers is also largely unaffected by bending, thus leaving the optical fiber bandwidth essentially unimpaired. Bend performance results were established by DMD measurements of fibers wound on mandrels vs. measurements of fibers with no severe bends.
摘要翻译： 该说明书描述了具有特定设计参数的多模光纤，即受控的折射率设计比和尺寸，这使得光纤在很大程度上免受适度严重的弯曲。 光纤中的模态结构也在很大程度上不受弯曲的影响，从而使光纤带宽基本上不受损害。 弯曲性能结果是通过DMD测量在心轴上缠绕的纤维与没有严重弯曲的纤维测量建立的。

摘要： An optical fiber ferrule has a plurality of guide holes therein for guiding a respective plurality of flat-sided fibers at an end of a multifiber optical fiber cable. The fibers' flat sides identify a particular rotational orientation of the fiber. Rotational alignment is achieved by urging the fibers' flat sides against a corresponding reference surface within the ferrule or within an alignment fixture. Also described is a fiber array block having a plurality of V-shaped grooves extending across an outer surface and terminating at an endface. The V-shaped grooves are shaped to guide a respective plurality of flat-sided fibers. A lid is installable across the plurality of V-shaped grooves, over fibers that have been loaded therein.
