Direct Attach Copper Cable LevelOne DAC-0101 10Gbps SFP+ 1m Twinax

The LevelOne DAC-0101 is a 1 m Direct Attach Copper (DAC) Twinax cable with SFP+ connectors on both ends, designed for 10Gbps Ethernet and 10G Fibre Channel short-reach links. This passive SFP+ cable delivers high port density and low power operation for data center and server room interconnects while meeting industry requirements for performance and reliability.

Advantages

The DAC-0101 supports multi-gigabit data rates up to 10.5 Gbps and is backward compatible to 1 Gbps. Its hot-pluggable SFP+ 20-pin footprint and I/O connectors are optimized for high-speed differential signaling. The cable follows the Improved Pluggable Form factor for enhanced EMI/EMC performance and is compliant with SFP+ MSA. It operates reliably in the 0 to 70 °C temperature range and is RoHS compatible.

Suitable for

• Short-distance 10Gbps connections between switches and servers
• Top-of-rack and middle-of-row data center links
• Direct connections in server rooms and SAN environments using 10G Fibre Channel

How to use

Insert one SFP+ connector into the SFP+ port of your network switch or server and the other connector into the corresponding port on the peer device. Ensure both ports support passive SFP+ twinax cables. The cable is hot-pluggable, so it can be connected or disconnected while devices are powered; however, verify link status after insertion. For best results, avoid sharp bends and keep cable length within the intended 1 m distance.

Recommendations

Use the LevelOne DAC-0101 for short-reach direct connections where a cost-effective, low-power 10Gbps link is required. Confirm device compatibility with SFP+ passive twinax modules and maintain ambient temperatures within the 0–70 °C range for reliable operation.
