Abstract
A typical optical fiber is coated with UV curable resins in order to protect the glass. The coating consists of two layers, a soft inner primary layer and a hard outer secondary layer. The coatings are cured using ultraviolet irradiation. The polymerization reaction generates heat and because the coefficient of thermal expansion of the primary layer is greater than that of the secondary layer, a negative hydrostatic pressure is generated in the primary layer during the cooling process that has the potential to delaminate the primary layer from the glass. In order to ensure the long-term reliability of the optical fiber, it is important to accurately determine the adhesive force of the glass/primary interface. In this paper, we will report on a new glass/primary adhesion measurement met遊雅堂 インスタント銀行送金d that has been developed for that purpose.
