Product Details

1) Support to detect optical signals without disrupting traffic; Based on non-destructive technology;

2) Indicate the signal direction in fiber;

3) Detect a variety of optical tones, 270Hz, 1kHz and 2kHz;

4) Suitable for 0.25, 0.9, 2.0, 3.0mm fiber, and no need to replace the clamp block, more convenient than others;

5) Build in visible fault locator 1mW or 10mW optional

6) Battery low indication;

7 Powered by 2 units of 1.5V AA alkaline batteries;
