Microbending losses in double-coated optical fibers caused by axial strain-induced creep deformation of polymeric coatings

Compressive radial stress on the glass fiber has caused microbending losses and hence microbending losses in double-coated optical fibers that are caused by axial strain-induced creep deformation of polymeric coatings are examined. The thickness and YoungEs modulus of the secondary coatings should be large enough to withstand an external mechanical force when the thickness and physical properties of the polymeric coating are chosen to minimize the microbending loss.
