SERVICE TIME AND DEFORMATION OF NEW OPTICAL FIBRES

Анотація

We study the dependence of the optical fibre lifetime on the tension. A method for calculating the elongation of the optical fibre depending on the bending radius is proposed. Recommendations on the bending radius choice of the fibre in the design of optical networks to increase their reliability are given. New optical fibres have reduced permissible bending radius, which results in considerable reduction of optical network lifetime, i.e., its reliability reduction.

Keywords: optical fibre, tension, bends radius, reliability, lifetime.
