Optical fibre jacketed with high-modulus low-linear-expansion-coefficient polymer

Abstract

A high Young's modulus, low-linear-expansion-coefficient-polymer loose-jacket optical fibre has been developed using orientated polyoxymethylene (POM), which exhibits Young's moduli 20 to 40 GPa and linear expansion coefficients ≤ 10−6°C−1. The highly orientated POM loose-jacket fibre has no microbending losses in a temperature range −60 to 80°C. A high Young's modulus, low-linear-expansion-coefficient-polymer loose-jacket optical fibre has been developed using orientated polyoxymethylene (POM), which exhibits Young's moduli 20 to 40 GPa and linear expansion coefficients ≤ 10⁻⁶°C⁻¹. The highly orientated POM loose-jacket fibre has no microbending losses in a temperature range −60 to 80°C.
