ABSTRACT

To maintain the mechanical strength, a commercialised dual-coated optical fibre is usually constructed of a glass fibre clad by two polymeric coating layers. Although the glass fibre behaves like an elastic medium, polymeric coating layers are typically made of viscoelastic materials. In this paper, the time-dependent interfacial residual shear developed in a dual-coated optical fibre is thoroughly investigated using the Maxwell’s model of viscoelasticity.
