Live Optical Fiber Identifier with Wave Respond 800-1700nm Built in 10mw 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.

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.

For the money, you would think it would be more durable. If you drop it once it’s over. I’m not joking. I’ve purchased multiple of these. Works really well. But it’s made of glass. Had to wrap my new one with electrical tape.
