摘要

本文分析了雙鍍層光纖中軸向應變所引起的應力，並導出了光纖中的側壓力，徑應力，切應力和軸應力。光纖中的正應力正比於軸向應變，並受第一鍍層和第二鍍層的材料特性和厚度的影響。此外，本文也討論了雙鍍層光纖中軸向應變所引起的微曲損失。

The axial strain-induced stresses in double-coated optical fibers are analyzed. The lateral pressure, radial stress, tangential stress and axial stress in The optical fiber are derived. The normal stresses in the optical fiber are proportional to the axial strain, and are determined by the material properties of the primary coating and secondary coating and their thicknesses. Additionally, the microbending losses induced by the axial strain in double-coated optical fibers are also discussed.
