    • works for regular campus LANs
Model: OPM&VFL-Li
Definitely opt for the rechargeable model! Unlike most others I'm not a fiber tech who works on FTTH/GPON systems. I use this for troubleshooting regular two strand fiber connections in large LAN environments facing OM1-OM4 and Single mode cabling. This tool is exactly what I was looking for in troubleshooting down or low db fiber connections. I had to calibrate the tool with a +5db, but now I can tell if the root cause is my jumper, SFP, uplink port, or bad pair in the long run fiber. I also use the VFL for verifying the patch is correct on the fiber shelf, locating where my jumper connects when there is a huge amount of them, and of course faults with the jumper. ... show more

    • Reads low, but consistently low. Very workable for the price.
Model: OPM-VFL-1
I like how the first 5 I tested were all within a 1dB tolerance of each other. For this price, I can adjust my thinking. I would rather buy 10 of these, than 1 $300 unit.

    • Great Tool, useful on the field
Model: OPM-VFL-2

Review Image by Jonathan Jonathan
I work at a fiber optic internet company, it’s been very useful and it has all my needs on the field. We get optimeters for testing light, they take forever to turn on and there is no VFL on our models. It’s so convenient having instant access to check light levels that you can store in your pocket all the time. The VFL is handy and bright, only downside is after 5-10 minutes it automatically turns off. I wish if the VFL is on then it won’t turn off but it’s not a big deal. I highly recommend calibrating to your fiber optic wavelength and light levels, the out of box experience is good with about 3 DB off but it’s great for a general estimate when it’s not very important. After calibration even after a couple months it’s been accurate and works very well. The battery life is pretty good, it uses 2 AAA batteries and it lasts me about a month or bit more. I love the Ethernet tester that is built onto the removable slot on the bottom. On the field I also work with CAT 6 and it’s great having it on the tool, I never have to carry around a separate Ethernet tester or ever run to my truck to find it. It’s helped me out in situations I never expected. The only major downside I had is the screen. When I first bought it, after about a month half of the screen was not working and was affecting my readings. I exchanged it for a new one and been very careful with the screen and making sure it won’t get dropped or damaged. It’s been a couple months and it’s been working just as it’s new. Overall, I love this tool and it will be a must need for me when I’m on the field. ... show more

    • Works as expected, good for the money - but its a guessing game to figure out
Model: OPM-VFL-1
I have this meter and have been using it for a while. Seems to be accurate. Works pretty good. Good value for the money. Only trouble is figuring out how to use it. Came with minimal instructions written in fine engrish. Not sure what the USB port is for. RJ45 appears to be only for Cat/5/6 cable testing? Or can you use it for waveform testing? Optical ports only seem to support FC for testing, but listing said it would support SC and ST too. Maybe an adapter was supposed to come with it that didn't? Anyway, like I said guessing game but for $30 what would anyone expect. At least it works. ... show more

    • I actually love this thing
Model: OPM-VFL-1
Light meter and visual fault locator in one package. That’s very handy and it’s in a compact form. It’s less than half the size of my company supplied meter. Plus I don’t have to carry two tools when I can carry one. The large backlit screen is also great for my aging eyes. Easy to read. It comes with a single led as a “flashlight” but that’s a really gimmicky feature. I’d never use it for anything, but points for trying. I didn’t buy it for that so no big deal. It also comes with a little lanyard. I should’ve left it off because I keep my meter in a tool pouch. All it does is catch on my needle nose pliers. It’s pretty annoying. The auto shut off feature is nice if you are using the light meter. But not so great if you need if for VFL. The way I use these tools it almost never a factor. I think you can toggle it off, but it’s something to be away of if you need to check continuity of a long fiber run. ... show more

    • Very easy to use, helpful!
Model: OPM-VFL-1
I’m a wire technician, working with fiber optic cables every day. The laser is brighter than other lasers i’ve used, making finding faults and finding my fiber in a bundle easy. The light reader is accurate, within .5dbm of my work issued light meter. Having both a laser and light meter in one compact device is great. Helpful tip, the unit is set to turn off after 10 minutes. once powered on, press the power button once to turn off this auto off feature. This device absolutely devours AAA batteries, so make sure to turn it off. ... show more

I’ve been using this for a good while now and it is mostly accurate, easy to use and carry wherever I go. Only issue I’ve found with it is the auto shut off after a few minutes. In some cases it’s good to save the battery but an issue when tracing a fiber line with the VFL function and not being able to find the end because it shut off on ... show more
