he 10G Passive SFP+ Twinaxial Direct Attach Cable is designed to support connections¹ for 10Gbps Gigabit Ethernet or Gigabit Ethernet switches with 10Gbps Gigabit Ethernet uplink, much more faster than SFP which only supports 2.5Gbps Gigabit Ethernet.

With four cable models including the DEM-CB100S, DEM-CB300S, DEM-CB500S, and DEM-CB700S, this series is suitable for very short distances (up to 7 meters) and is ideal for highly cost-effective networking connectivity between switches and servers within a rack or in adjacent racks.

The D-Link 10G Passive SFP+ Twinaxial Direct Attach Cable supports speeds of up to 10Gbps, while having lower latency and power consumption than other cables types such as 10GBASE-CX4 and CAT6/CAT6A 10GBASE-T. This makes it an optimal solution for handling high bandwidth transmission within short distances such as inside energy-efficient data centers.

The D-Link 10G Passive SFP+ Twinaxial Direct Attach Cable uses Enhanced Small Form-factor Pluggable format (SFP+) connectors. The SFP+ form factor is smaller than other form factors such as Xenpak, X2, and 10G XFP, resulting in lower costs, lower power disruption, and higher port density. Meanwhile SFP+ connectors use the same space-per-port as standard SFP connectors but support higher data transmission speeds.

The D-Link 10G Passive SFP+ Twinaxial Direct Attach Cable features SFP+ connectors on both ends, thus eliminating the need for expensive SFP+ transceivers. This makes it more cost-effective than fiber cables which must use SFP+ transceivers.
