Apparatus for locally abstracting light from the core of a buffer coated optical fibre, especially a buffer coated single mode optical fibre, suitable for use when monitoring the fusion splicing of optical fibres comprises a body of perspex having at least three faces, an arcuate contact face adapted to bear against a smoothly curved length of buffer coated optical fibre, an exit face through which light entering the body through the contact face can emerge and a reflecting face which will reflect light entering the body through the contact face in a direction towards the exit face. Light emerging from the smoothly curved length of buffer coated optical fibre and passing through the contact face into the body will be directed and reflected towards the exit face from where it can pass into a light detector. |
