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.
Switch on the unit only when the protective cap is in place or a connector is attached to the outlet.
Press the PWR button. The locator emits a continuous or pulsed signal depending on the setting selected with the MOD button.
The visual defect locator is compatible with all connectors with a 2.5 mm ferrule. For 1.25 mm ferrules, the use of an adapter is required.
The locator can be used on links up to 10 km. Beyond that, whatever the power of an optical pencil, the light beam cannot be perceived.
The end of an optical link is detected by the presence of the light signal. This is a function widely used for mixing garters in street cabinets or bays.
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.
After using the device, turn off the locator and place the protective cap on the optical output.
