Information

Main Functions

Support to detect optical signals without disrupting traffic; based on non-destructive technology.

Indicate the signal direction in fiber.

Detect a variety of optical tones, 270Hz, 1kHz and 2kHz.

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

Build in visible fault locator 1mW or 10mW optional.

Battery low indication.

Powered by 2 units of 1.5V AA alkaline batteries.
