摘要: According to the invention, the intermediate sheath (13) is formed by assembling longitudinal elements (13A) and includes: a first optical material, the refractive index of which differs from the refractive index of the monomode core by at most 10
-3 ;
and a second optical material, the refractive index of which is lower than the refractive index of said monomode core and differs therefrom by at least 10
-3 .摘要翻译: 根据本发明,中间护套(13)通过组装纵向元件(13A)而形成,并包括:折射率与单模芯的折射率不同至多10-3的第一光学材料; 以及第二光学材料,其折射率低于所述单模芯的折射率,并且与其不同至少为10-3。
