The fibre identifiers, used for identifying the light power presence in optical fibres, include three detecting functions: TONE, TRAFFIC, and ONU. Both models include a trigger operated clamp to macro-bend the fibre in order to leak light which is then detected by two photo sensors. The fibre identifiers can detect the presence of several kinds of light signal and indicate signal directions. The fibre identifiers can be used for UV-coated fibre, 0.9mm diameter tight buffered fibre, fibre cord up to 3mm in diameter, and fibre ribbon with up to 12 fibres.
