1mW Fiber Optic Visual FaultLocator

In order to achieve a longer test distance, this visual fault locator adopts a short-distance focusing method in the connector, which is different from the long-distance focusing method of the laser pointer.  

The distance that can be tested for 3~5 kilometers is under the circumstance as
1. 25℃ room temperature
2. Using  Ø2.5mm ST/SC/FC connector with multi-mode optical fiber cable. In addition, the light can not even reach 3 kilometers may be because of low battery, bad connector, error cable, etc.

Reminder: If you are testing single-mode fiber, the distance will be reduced by about 1/2. If you use an adapter or test with Ø1.25mm LC connector, each contact will lose 1/5 of the distance.

"CW" means continuous wave，which is used to transmit the laser for a long time to check the loss.

"Glint"  is generally used for reminding the operator,  allowing you to quickly detect the location of the break point.
