fyboptwu4 in 1 Function 10MW VFL Visual Fault Locator & OPM Portable Optical Power Meter (FC/SC/ST) & RJ45 Network Test & LED Lighting, Portable Fiber Optic Tester

Accurate and solid. I've had it in the field for about 6 months with no issues

Purchased this as a backup and as a training device. When compared to my more expensive optical meter on numerous occasions, it surprisingly produced the exact same power reading. Unit has proven to be accurate, and the VFL functions properly as well.

Funciona bien

While the use-case for fiber optic testing devices is growing in modern businesses, my personal need for a quality testing device is increasing at an accelerated rate. I work in I.T and even some of our residential clients are requesting fiber optic circuits to be installed in their homes.When comparing the results to more expensive meters we have used they are within very reasonable variance. For something that costs about 3x less, it is 100% fine. The included RJ45 cable tester provides accurate results as well, and even accurately detected an intermittent fault that another meter of ours looked over. I'm very satisfied with the test results of this meter. It is extremely lightweight and easy to carry, though some may prefer the feel of a heftier tester, I personally don't mind lowering the weight of my tool bag.In terms of practicality, this tester is punching far above its price range and is a tool that is growing to be increasingly required across a multitude of industries. I would recommend picking one up to add to your toolbag if you are looking to improve your wiring skills and versatility.
