I believe the question is probably about the fiber transceiver for SFP+. We do not sell that. Customers can use either a co-ax copper cable for connections or they can use fiber. They can obtain the fiber transceiver from third parties. I am not sure who might be a good vendor in your territory - but we have found that a company named Digi Key (www.digikey.com) offers them. It appears that they have a European presence.
