多芯光纤
摘要：
本实用新型提供一种多芯光纤，使具有降低串扰的效果的空孔等副介质区域的配置简化，比较容易制造。本实用新型的多芯光纤（1）包括：配置成位于多边形环的顶点的第一纤芯（11a～11c）及第二纤芯（12a～12c）；以及包层（14），该包层形成有空孔（13a～13f），并覆盖第一纤芯（11a～11c）及第二纤芯（12a～12c），并且折射率低于第一纤芯（11a～11c）及第二纤芯（12a～12c）。空孔（13a～13f）配置于降低第一纤芯（11a～11c）及第二纤芯（12a～12c）之中相邻的纤芯之间的串扰的位置。
摘要（英）：

The utility model discloses a multi-core optical fiber, which simplifies configuration of empty holes or other subordinate medium regions with an effect of reducing a crosstalk and is comparatively simple to manufacture. The multi-core optical fiber (1) comprises first fiber cores (11a-11c) and second fiber cores (12a-12c) which are configured to locate on vertexes of a polygonal ring, and a covering layer (14) which is formed with empty holes (13a-13f) and is used for covering the first fiber cores (11a-11c) and the second fiber cores (12a-12c), and the reflectivity of the covering layer (14) is lower than the reflectivities of the first fiber cores (11a-11c) and the second fiber cores (12a-12c); and the empty holes (13a-13f) are configured to locate on positions for reducing the crosstalk between the adjacent fiber cores of the first fiber cores (11a-11c) and the second fiber cores (12a-12c).
