What customers say
Ordering and using FLEXOPTIX transceivers was far quicker than even getting a quote from traditional vendors.
Using the FLEXBOX is super easy and fast - 5 minutes to get transceivers ready including unboxing and enjoying packaged marshmallows.
I personally did not know FLEXOPTIX yet, but since I got in contact with it the first time, I do not want to miss it anymore. Very good product. I like the ability to program them to vendor specific SFPs which are recognized as they would be original ones. If the hardware behind changes I can simply change the SFPs to new vendor specific ones.
Thank you for such a great product.
Woa, i can get next day delivery for any vendor. That’s a game changer. Also thanks for making it a smartphone app, this fits my workflow well.
The SFPs easily integrated with our existing network equipment, ensuring cross-vendor compatibility. The build quality is very good.
Connecting to the FLEXBOX with an Android phone took only a few seconds, and configuring the SFPs was a breeze. We really liked the ability to configure multiple SFPs at once. Shipping is incredibly fast. Support is friendly, technical and helpful.
