The visual defect locator (or optical pencil) emits red light at an output power of 10 mW. Do not directly look at the light beam or direct it at another person. Always replace the protective cap after use.

<!--T:4-->
Switch on the unit only when the protective cap is in place or a connector is attached to the outlet.</translate>

Locating the defect  (a curve for example)</translate>

Due to the high reflection of the light as it passes through a stress (macro-curve) or when a fibre is cut, this device is widely used to correct defects (which cause significant optical losses), on the visible part of the fibres.</translate>
