Optical fibre joint

摘要

A simple and inexpensive optical fibre joint comprises an elongate core consisting of an assembly of rods defining between their adjacent radially outer surfaces a plurality of interstices; an elastomeric sleeve tightly surrounding the core; and two optical fibres aligned in one of the interstices with their neighboring end faces abutting or closely spaced apart. The depth of the interstice and the degree of expansion of the elastomeric sleeve having regard to the diameters of the aligned optical fibres are such that the optical fibres are tightly held in the interstice. The rods constituting the elongate core may be of rigid material or of an elastomeric material.
