Live Optical Fiber Identifier with Wave Respond 800-1700nm Built in 10KM VFL and Optical Power Meter OPM Functions FTTH Tool (YD-3309D)

I've used alot of traffic meters and for the money, it's doesn't get any better than this! Also would be a great back up. Shows traffic direction, and strength! I've bought 2.

Great price for A much used tool when working with fiber optics

First off, it's a traffic identifier not a power meter, so it serves its purpose. If you are looking for an accurate reading not affected by ambient light splice on a tail and get yourself a meter. Otherwise, it's great. It picks up tone and they even threw in a vfl on the end, so overall good deal.

Value of money is great.

Can't use. This thing gives all fibers a positive signal when they are dead fibers. Can't use to find live fiber not useable and honestly not worth the money considering it don't even work. The meter isn't accurate either. This is a expensive vfl nothing else works.

Works great for the price. I’ve use it several times and haven’t had any problems.

Excelente producto, funciona de maravilla

Good for knowing which direction the light goes, but don’t trust any of these to see if their is light in the fiber
