Perfect way to test Fiber/SFPs

By: andrewxs11 - 06/29/2018
This is a great adapter and has made its way into my travel bag as a permanent addition. It’s small and easy to carry around, but delivers very big performance. I have tried many SFP’s to test their functionality, and also used it to then test fiber cables, and ports on SFP switches. It never fails to recognize the SFP, no matter the brand, and the activity lights are beside the SFP port, which makes them easy to see, even at a distance. An excellent tool if you work with any kind of Fiber! I received this product in exchange for an unbiased review
