Abstract

Одномодове оптичне волокно з дисперсійним зсувом має оболонку й охоплену нею серцевину із профілем показника заломлення, що містить три ділянки. Перша ділянка має першу точку на осі світловодного волокна, останню точку на радіусі А1, максимальний показник заломлення nі, відносну різницю показників заломлення Δ1%. Друга ділянка має першу точку безпосередньо за радіусом А1, останню точку на радіусі А2, максимальний показник заломлення n2 і відносну різницю показників заломлення Δ2%. Третя ділянка має першу точку безпосередньо за радіусом А2 і останню точку на радіусі А, максимальний показник заломлення n3 та відносну різницю показників заломлення Δ3 %.
