1.7.2. Copper Platform
A 10/100/1000 Mbps Ethernet MAC and an internal system are implemented in the FPGA. The internal system retrieves all frames received by the MAC function and returns them to the sender by manipulating the MAC address fields, thus implementing a loopback. A direct connection to an Ethernet link is provided through a combined MII to an external PHY module. Certified 1.25 GBaud copper SFP transceivers are Finisar* FCMJ-8521-3, Methode* DM7041, and Avago Technologies* ABCU-5700RZ.
