i see other testers around less then $100 that do +25mW from the product page it states <1.3 mW output power, is this accurate?

The output power level listed on the device is < 1.3 mW; wavelength 630-670 nm; class II laser product. I will tell you that the device works very well across great distances. The light source is very strong so it may be a combination of power level and wavelength that make it work well. Also we use a lot of Fluke devices and find them to be very reliable although a bit more expensive.

How far will this device test. can i test a 15km or 20 km length of fiber with it

Thank you for your question. The Visifault has a range of 3 km on Multimode fiber and 4 km on Singlemode fiber.

What is the Wavelength this Fault Locator

Diego, the output of this device is <1.3 mw and the wavelength is 630-670 nm. It is a class II laser product. This information taken off the label on the unit itself.

What is the warranty?

Check on Flukes website.I will say these things are absolutely indispensable. We use them daily to set up very large area (Railroad) fiber networks around the worldThey are very rugged, and we have never had a problem.They have been of sufficient value and reliability that even if there was no warranty, I wouldn't hesitate to purchase them.
