Physical property evaluation method for optical fiber coating, and coated optical fiber |
摘要 |
A physical property evaluation method for optical fiber coating which is easy in producing a sample and high in accuracy and which is capable of measuring the shear modulus or tensile modulus with high accuracy, and a coated optical fiber with good lateral pressure characteristics using this evaluation method. The method comprises a step of producing a sample with the both end faces being parallel by cutting a coated optical fiber by a plane normal to the direction of the center axis of an optically transparent member, a step of holding the sample by securing the second coating layer, a step of pushing only the optically transparent member to impose a load thereon, thereby giving displacement to the optically transparent member and causing shear elastic deformation to the first coating layer, and a step of calculating the shear modulus or tensile modulus of a material forming the first coating layer, based on an amount of the displacement of the optically transparent member and a value of the load imposed thereon.
