Title (EN) MULTICORE FIBER
(FR) FIBRE À ÂMES MULTIPLES
(JA) マルチコアファイバ
Abstract:
(EN) The present invention is characterized by the following: a plurality of cores 10 and a cladding 15 that surrounds the plurality of cores 10 are provided; each of the cores 10 has an inner core 11 and an outer core 12, which surrounds the inner core 11 with no gap therebetween, and which has a refractive index higher than that of the inner core 11 and the cladding 15; no rare earth elements are added to the cores 10; and light of two or more LP modes and having a prescribed wavelength is propagated through the cores 10 with a loss of 0.3 dB/km or less.
(FR) La présente invention est caractérisée par les éléments suivants : une pluralité d'âmes 10 et une gaine 15 qui entoure la pluralité d'âmes 10 ; chacune des âmes 10 comprend une âme interne 11 et une âme externe 12 qui entoure l'âme interne 11 sans espace entre elles et qui possède un indice de réfraction supérieur à celui de l'âme interne 11 et de la gaine 15 ; aucun élément de terres rares n'est ajouté aux âmes 10 ; et la lumière de deux modes LP ou plus et ayant une longueur d'onde prescrite est propagée à travers les âmes 10 avec un affaiblissement inférieur ou égal à 0,3 dB/km.
(JA) 複数のコア10と複数のコア10を囲むクラッド15とを備え、コア10は、内側コア11と、内側コア11を隙間なく囲むと共に内側コア11及びクラッド15より屈折率が高い外側コア12と、を有し、希土類元素がコア10に非添加であると共に、所定の波長の2つ以上のLPモードの光が0.3dB/km以下の損失でコア10を伝搬することを特徴とする。
