Abstract

Винахід стосується варіантів одномодового оптичного волокна. Одномодове оптичне волокно має серцевину, яка характеризується центральною лінією на поздовжній осі цього волокна, з радіусом, профілем показника заломлення й максимальним показником заломлення, і шар оболонки, що охоплює серцевину й характеризується профілем показника заломлення й максимальним показником заломлення nc. В серцевини ділянка профілю показника заломлення перевищує nc. Максимум показника заломлення віддалений від центральної лінії, гострий мінімум профілю показника заломлення знаходиться біля центральної лінії, і ця лінія є віссю симетрії профілю показника заломлення.
