Fiber Optic Cable Tester - Portable Optical Fiber Power Meter with Universal FC/SC/ST Interface and Built-in 2Mw Visual Fault Locator (OPM-VFL-2)

Awesome little tester. Got the rechargeable one and use daily haven't had to recharge yet for months now. I use it for readings around 15 to 20 times a day, them immediately turn off. So far works well, gets same readings as a Viavi $120 meter. I use for GPON and XGS fiber readings.

Great product and timely delivery

This thing is absolutely fantastic. Despite not being designed to read 1577 nm light, it still reads it quite accurately when set to 1550. I sometimes have only a1-2 db variance compared to a $150 light meter I have on hand. The visual fault locator is WONDERFULLY bright and works fantastic on APC and UPC connectors. I can easily determine where issues are, and it is frankly brighter than a $100 VFL I have. Fantastic features that are way better than a $28 package has any right to include. It feels sturdy, with a fairly hard rubber shell that I feel could easily handle drops onto concrete, unlike the $150 light meter I have. I use this more often than I use the other one now.

Works great. I've been able to shoot a light down a fiber more than 4 miles. Stayed charged for several hours of troubleshooting.

Best power meter good working

Great value for the money, that has let me test many many fibers at this point.

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.

Works perfect. Hold down the “light” button to activate the red dot on the left port. Use it all day in professional atmosphere.
