http://www.networkworld.com – The majority of data center LAN links use 1000Base-T (Gigabit Ethernet) running on unshielded twisted pair structured cabling (Cat5e, Cat6, Cat6a). While increasing demand for bandwidth is driving a shift to 10G Ethernet, that migration is being slowed by the fact that the 10G links being deployed today are based on optical transceivers or SFP+ Direct Attach copper, neither of which is backward-compatible to Gigabit Ethernet.
