Coated optical fibers, primary coating composition, method for curing, as well as an assembly and a method for measuring |
摘要 |
<p>The invention relates to coated optical fibers comprising soft primary coatings and to such primary coatings for protecting glass optical fibers having a sufficient high resistance against cavitation. In particular, the primary coatings have a cavitation strength at which a tenth cavitation appears ( sigma <10>cav) of at least about 1.0 MPa as measured at a deformation rate of 0.20% min<-1> and of at least about 1.4 times their dynamic modulus at 23 DEG C. The coating preferably shows strain hardening in a relative Mooney plot, preferably has a strain energy release rate Go of about 20 J/m<2> or more, and preferably has a low volumetric thermal expansion coefficient. The invention furthermore provides a method and apparatus for measuring the cavitation strength of a primary coating.</p> |
