Apparatus for injecting light into the core of a buffer coated optical fibre, especially a buffer coated single mode optical fibre, suitable for use when monitoring fusion splicing of optical fibres comprises a transparent body 1 having at least three faces, an arcuate contact face 2 adapted to bear against a smoothly curved length of buffer coated optical fibre F, an entry face 3 through which light emitted by a light source S is injected into the body in a direction towards the contact face, and a reflecting face 4 which reflects injected light in a direction towards the contact face. Light injected through the entry face 3 is directed and reflected towards the smoothly curved contact face 2 from where it will pass through the buffer coating and cladding of an optical fibre F against which the body bears into the core of the optical fibre. <IMAGE> |
