Altera offers the 40 Gbps Ethernet (40GbE) and 100 Gbps Ethernet (100GbE) MegaCore® function intellectual property (IP) cores for building systems with very high throughput-rate standard Ethernet connections. These IEEE 802.3ba-2010 40 Gbps and 100 Gbps Ethernet standard compliant media access control (MAC) and PHY (PCS+PMA) IP cores enable an Altera® device to interface to another device or to an optical transceiver module and, in turn, to 40GbE and 100GbE networks.

Figure 1 illustrates an example of Altera 40GbE or 100GbE MAC with a XLAUI, CAUI or CAUI-4 interface in an Altera device. 40GbE and 100GbE are two different IP cores.
