Fiber Optic Cable Tester Portable Optical Fiber Power Meter FC/SC/ST Universal Interface Integrated OPM, VFL, and RJ45 Functions (OPM-VFL-2)

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.

Lo mejor de lo mejor

Has been very useful and accurate. Fits perfectly in a small pocket/cargo pocket.

My only criticism is that I wish it was battery powered instead of using batteries

yes the OPM works (some what, i only use it as a ROUGH power estimate, as simply moving it around will widely effect the reading- but it still is useful as a ROUGH power estimate. however much more Important is that the VFL will auto power off after only a few minutes. Sometimes fiber runs can be a (little) long- so you might need some time when using a VFL - however when you cant trust if you VFL will still be on when you get to the other side / patch panel / xyz location - the VFL becomes USELESS. If the user runs the batteries out, thats on them. but if the device turns off the VFL arbitrarily then it's useless and can't be trusted.

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

Light levels can’t be calibrated to my everyday use for it. It will tell me if theirs light. So that’s a good thing

Great little tool if you are using fiber connectivity. A+ You do though need a way to have ST ends (converted somehow) to use this tool if you have LC, SC, or any other end.
