Hi, we have a kintex7 development kit, and for some project we have we need 2 gigabit ethernet ports. The board has only one built-in but it also has an SFP port, which making some browsing I found out that you can attach an RJ45 copper module. I have two questions:
1. Can I use any RJ45 module and use it almost transparently in the project?
2. All modules I find implement SGMII, while I need RGMII. Is it that SFP only implements SGMII?
3. Any other recommendation on how could I attach a second ethernet port to the board?

Thanks for replying. I can't use the option you recommend, as I am planning to use it for EtherCAT, and the chipset that comes with that device is permanently programmed for preamble suppression, which then makes it not good for it. I am still looking for other FMC or SPF solutions. Thanks!
