摘要： A low attenuation optical cable is provided. The cable includes an outer cable jacket and at least one buffer tube surrounded by the cable jacket. The cable includes a plural number of optical fibers located within the channel of the at least one buffer tube. The cable includes small sized active particles located within the buffer tube, and an average maximum outer dimension of the active particles within the buffer tube is ≤ 50 microns. The small sized active particles reduce microbending-based attenuation otherwise seen with larger sized active particles, particularly within densely packed buffer tubes.

摘要： An airline (AL) optical fiber ("AL fiber") that has an AL region with airlines, with the AL region arranged relative to the fiber core so as to make the fiber bend insensitive. The AL region is capable of supporting one or more higher-order optical modes. One method of reducing multipath interference (MPI) includes accessing a section of the AL fiber and closing at least one of the airlines in the section. This serves to attenuate one or more higher-order modes, which reduces MPI. In one example, the AL fiber has an end section wherein the airlines are filled with a blocking material. An example blocking material is a curable adhesive that is wicked into the airlines via capillary action and then cured when the adhesive reaches a certain depth from the fiber end. In another example, the blocking material is formed by heating the AL fiber section to cause the section to melt and block the airlines, so that the melted AL fiber serves as the blocking material. The AL fiber with reduced MPI is particularly useful as a "jump" fiber, whose length is too short to rely on attenuating higher-order modes via a cable cut-off wavelength.
摘要翻译：具有AL区域的航空公司（AL）光纤（“AL纤维”），其中AL区域相对于纤维芯布置，以使纤维弯曲不敏感。 AL区域能够支持一个或多个高阶光学模式。减少多路径干扰（MPI）的一种方法包括访问AL光纤的一部分并关闭该部分中的至少一个航空公司。这用于衰减一个或多个更高阶模式，这降低了MPI。在一个示例中，AL纤维具有端部，其中航空公司填充有阻挡材料。示例性阻挡材料是通过毛细管作用被弄脏到航空公司中的可固化粘合剂，然后当粘合剂从纤维端达到一定深度时固化。在另一个实例中，通过加热AL纤维部分以使该部分熔化和阻挡航空公司形成阻挡材料，使得熔融的AL纤维用作阻挡材料。具有降低的MPI的AL纤维作为“跳跃”光纤是特别有用的，其长度太短而不能通过电缆截止波长衰减高阶模式。

摘要： A multicore optical fiber includes two or more cores, a common interior cladding surrounding the two or more cores, and a common exterior cladding surrounding the common interior cladding. The common exterior cladding has a lower relative refractive index than the common interior cladding and reduces tunneling losses from the cores. The reduced tunneling loss allows placement of cores closer to the edge of the fiber, thus providing multicore optical fibers having higher core count for a given fiber diameter. Separation between cores is controlled to minimize crosstalk.

摘要： A quasi-single-mode (QSM) optical fiber includes a core and a cladding surrounding the core. The core includes a centerline and an outer edge. The cladding includes an interior edge and an exterior edge. The cladding has a cladding outer diameter defined by the exterior edge of the cladding. The cladding outer diameter may be in the range of greater than 170 µm to about 200 µm. The QSM fiber has a cabled cutoff wavelength that is greater than about 1530 nm. The core and the cladding support a fundamental mode LP 01 and a higher-order mode LP 11 . The fundamental mode LP 01 has an effective area A eff > 150 µm 2 .
