A method of forming a butt splice between members for carrying optical signals, which comprises bringing the ends of the members into abutment and applying between the ends or applying to at least one of said ends a coupling composition that comprises a liquid having the same or substantially the same refractive index as the members, the liquid having dispersed therein a viscosity increasing agent that also has the same or substantially the same refractive index as the member, the coupling composition being flowable. |
