What customers say
Have been using FLEXOPTIX transceivers for a few years now in a carrier/telecoms environment for various vendors and they've never disappointed me. After having the opportunity to be able to program them myself on demand, I've realized how many hours I could have saved until now with FLEXBOX! No large stocks, just a few generic SFPs in stock waiting to get programmed when needed. Awesome!
We are using FLEXOPTIX industrial grade transceivers in our control systems for power electronics and converters. The FLEXBOX is an invaluable tool, making it super easy and quick to configure transceivers. Even larger numbers can be configured easily with the batch configure option, just plug them in one after the other and the rest happens automatically. The power meter, source control and OTDR features are helpful for lab testing or during commissioning. Thanks, FLEXOPTIX for providing universal transceivers of a high quality at decent prices! Your lightning-fast order processing and shipping speed is also impressive.
We heard about FLEXOPTIX for the quality of its FLEXBOX and optics.
We were able to acquire a FLEXBOX to help out our customers. The quality of the product leaves us speechless. We are immediately going to change optics supplier to FLEXOPTIX. The quality is excellent.
I have received my orders from them in blistering speed. Happy to the nth degree.
