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.

A good product.

This product works very well for testing fiber optic cables. Its small size, easy to use and its portabbility is a plus.

Not your typical Fluke quality

Haven’t used this yet to fault locate, but the dust cap is way to sloppy to effectively protect from dust. So loose it pops off on it’s own. Will revisit review after use to fault locate.

Dropped From Top of Ladder and It Still Works Flawlessly

The Fluke Networks VISIFAULT Visual Fault Locator is a PROFESSIONAL VFL. I've purchased two other cheap "flashlight" VFLs from Amazon but they are faulty and not made for daily professional use, that is, constant switching them on/off and dropping them. Also, the Fluke VFL produces a sharp, bright, round red light without ridges like the other $25 range VFLs give you. This becomes important when you have to splice fiber and determine if the splice is good by shining the red light against a flat surface to see if the light's shape and output is the same as if you are shining the VFL straight out of the unit. The cons of this VFL is the bulkiness and no way to dangle it (I have to strap the VFL against the wall with tape or tie it down when there's no way to lay it down while I go check the other end). It's also expensive but it has lasted me over a year and I've only changed out the batteries once or twice.
