MT-7501E

The light of the visual fault locator is too weak may shorten the test distance? The test distance farther only if the light gathering ability is greater?

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 light of can not even reach 3 kilometers when testing on the optical fiber network

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.
What's the difference between "CW" and "Glint"? What are they used for?

"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.
