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

Love this thing. Saves my butt daily.

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.

it works to let you know there is light. however the reading is not too accurate. shows intermittent readings, actual numbers and direction fluctuates alot. maybe faulty meter. its works enough for now. not expecting it to last too long.

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.

Good but not so accurate
