As you know, the price of SFP28-25GER-31-Imodule is 279,00 € and the price of SFP28-25GER-31 module is 799,00 €.
Please tell me what is the difference between these 2 modules.
The interesting thing is that the industrial module is cheaper.

Good news! I got the parcel today and all is well! I’m officially operating at 10Gb! You’ve got some fantastic products and unbeatable customer service.

I really appreciate your help and the high-quality products FS provides.

You're absolutely amazing. Thank you so much for the fantastic service!

I wanted to let you know how happy I am with your products!! I’ve successfully set up my new modules, and I’m up and running at the fastest speeds I’ve ever had!

I ordered my goods through your website and one day later they are already delivered. So you delivered the goods from your German warehouse to a Belgian location in one day … and that’s without asking for a faster delivery. That’s amazing these days. You guys know what you’re doing. I'm gonna change de initials of FS into Fast Service.
