10 Gigabit Ethernet and Gigabit Ethernet on the Same Half Card
The Cisco TwinGig Converter Module (Figure 5) converts a single 10 Gigabit Ethernet X2 interface
into two Gigabit Ethernet port slots that can be populated with SFP optics, enabling customers to
use Gigabit Ethernet SFPs on the same card in combination with 10 Gigabit Ethernet X2 optics.
