Accurate Live Fiber Detection!

“I'm a fiber tech and got this tool to check if a fiber has traffic without unplugging it, and to detect a 2kHz tone. It does both really well. I use it with a light source to send the tone, and this device always picks it up. I tested it up to 6,000 feet with no issues. I'm happy with how it works.”

Why Get Our Optical Fiber Identifier?

✅ Fast & Accurate Fiber Detection: Finding the right live fiber can be tricky and time-consuming. This tool makes it easy by detecting signals from 800nm to 1700nm and showing power levels from -40 to 10 dBm. It also uses LED lights to show signal direction and frequency, so you can check fibers without unplugging them.

✅ Built-In Fault Locator: Equipped with a 10mW Visual Fault Locator and 2.5mm universal connector, it locates fiber faults, breaks, or bends within 10km, offering both pulse and continuous detection modes.

✅ Convenient for All Conditions: Work easily with an all-in-one chuck system that fits 0.25mm to 3.0mm fibers without needing swaps. A built-in LED light and backlit display ensure smooth operation even in dark environments.

📓FREQUENTLY ASKED QUESTIONS

Q: What does it mean when the device shows a number like -20 or -5 dBm?

A: These numbers show how much light power is in the fiber. If you see a value between -40 and 10 dBm, it means the fiber is active and carrying a signal. Higher numbers (closer to 0) usually mean stronger signals. 

Q: Can I use this for all types of fiber sizes without changing the chuck?
A: Yes. The all-in-one chuck fits 0.25mm, 0.9mm, 2.0mm, and 3.0mm fibers. You don’t need to swap parts for different cables, making testing faster and easier.
