Abstract

Винахід стосується одномодових оптичних (хвилевідних) волокон. Одномодове оптичне волокно має оболонку й світлопровідну серцевину, містить три концентричні частини з різними профілями показника заломлення. Перша розташована симетрично навколо поздовжньої осі симетрії волокна з максимальним показником заломлення n1, відносною різницею показників заломлення Δ1 % та радіусом r1. Друга частина охоплює першу частину й має максимальний показник заломлення n2, відносну різницю показників заломлення Δ2 % та зовнішній радіус r2. Третя частина охоплює другу частину й має максимальний показник заломлення n3, відносну різницю показників заломлення Δ3% і радіус r3.
