5-in-1 Fiber Optic Cable Tester - Portable Optical Power Meter With Light, FC/SC/ST Universal Interface

Easy to use, accurate

I am just starting to learn about fiber testing, just happened to need this on a job yesterday, so great that I had just received it and grabbed it before I left. The batteries/power/charging is confusing. My laptop USB C charging cable doesn't work on it but other cables do work. The instructions that come with it says that lithium batteries can be charged via the USB C port but lithium batteries are not normally rechargeable. So, not sure if it means lithium-ion batteries which are rechargeable. It does work on regular AAA batteries.

Excellent

So the charging port and option is the reason for purchase but when vfl engaged and it cuts off quickly…

I've been looking for a versatile OTDR with a large screen, I'm committed to maintaining a fiber optic network but most of them are costly, I'm glad I found this groword otdr, it's versatile and very affordable compared to other otdr's!

Not a good product. Very poorly built. It fell apart in about a week.

This tool is very useful for basic testing of a fiber connection (and safer than trying to look into the fiber). I was also surprised to find it also is a basic RJ45 copper tester. Useful tool to keep in your kit without worried about it being stolen or lost. Directions could have been better.

I bought this for a fiber job in 2023 that ended up not happening. So I ended up not using it until just the other week where I finally had another single mode fiber job that required OTDR testing with printable results. The tester worked great during testing. It reported the length of my fiber run fairly accurately. Even got the length of my launch cable accurately. So I'm pretty confident the db loss figures are accurate as well. But there's just one problem. How do I print the results?? I saved all the results to the internal memory but how do I print?? The product listing states it comes with software that needs to be installed on a PC but I didn't receive any software with my tester. I see no way to contact the seller or a web address to download the software either. I would honestly give this at least 4 stars if not 5 if it either came with the software or had a place I could download the software from. But without being able to print the results I would just have to buy a different one as most clients require printed results. What a waste of money. If all you need is results on the screen, I would say 4 stars would recommend. But if you're like me and need to print the results for your clients, get a different OTDR.
