Fiber Optic Cable Tester Portable Optical Fiber Power Meter FC/SC/ST Universal Interface Integrated OPM, VFL, and RJ45 Functions Li-ion Battery USB Charge (OPM&VFL-Li)

I bought the rechargeable one. Great to have in a toolkit. has a cat6 cable tester as well. Great value.

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

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.

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.

Works great so far! Haven’t used much can’t wait to try out all features!

Not user friendly, instructions unclear. Not what I expected.
