Abstract
A fibre optic terminal (1) for use with a bi-directional optic fibre (6) including an optical receiver (2) positioned in the path of light (8) emitted from an end (5) of the optical fibre to receive the light, and an optical emitter (4) arranged to emit light (7) from a position adjacent the optical receiver onto the end of the optical fibre, the position being in the path of light emitted from the end of the optical fibre so that substantially all of the light emitted from the optical emitter is incident on the end of the optical fibre, and the area from which the optical emitter emits light being small relative to the light receiving area of the optical receiver so that substantially all of the light emitted from the end of the optical fibre is received by the optical receiver.
