4-in-1 Fiber Optic Tester, Portable Optical Power Meter FC/SC/ST Standard Interface, Built-in 30Km Fiber Fault Detector Network Cable Tester with 1pc FC to LC Adapter

I purchased this in December of 2023 so I'm going on two years of using this OPM and it's honestly the best. The manual calibration is great, battery lasts long, and extremely portable. Purchase the Baoshla A-M1315 Optical Light Source and you have yourself a great little Optical Loss Test Kit for a fraction of the cost. I haven't ran into any issues using this OPM, it works just as it should, and the price is simply unbeatable. I definitely recommend to anyone looking for an OPM without having to spend hundreds of dollars. This bad boy is the real deal.

simple and rugged, nice to test cat 5 also

Puts out a wrong laser light and the convenience of a power meter built into the same unit is great. I have had several other units that do the same things separately but I really like having it in one unit. The Ethernet test unit is an added bonus.

Bought this meter, it's not calibrated correctly (light readings aren't accurate). This is the second one I've found like this coming from an overseas company, I recommend caution buying a light meter here if you need it to work

This little device works great and it’s easy to use and lightweight which helps out because with the work I do this really helps out

My husband loves it

Muy recomendado, excelente producto exacto según lo descrito.

La medicion de potencia no es la correcta, por mas que se calibre da una medicion incorrecta. Al calibrar solo la medicion a la cual se calibra la mide correctamente pero al medir alguna otra fibra da medicion incorrecta.
