Direct Attach Cable StarTech 1m SFP+ to SFP+ DAC 10Gbps Twinax passive, compatible with Dell EMC

The StarTech direct attach Twinax cable is a 1 m SFP+ to SFP+ passive copper assembly engineered for short-reach 10 Gigabit Ethernet links. Compatible with Dell EMC transceiver ports and compliant with MSA industry standards, this low-latency, low-power DAC supports high-speed connections between switches, servers and storage devices. The cable is hot-swappable for minimal service interruption and offers a cost-effective alternative to optical modules for in-rack point-to-point interconnects and port consolidation.

Advantages

This passive 1 m Twinax cable provides 10 Gbps throughput with minimal latency and reduced power consumption compared with active or optical solutions. Compatibility with Dell EMC SFP+ ports and adherence to MSA standards ensure reliable interoperability in mixed-vendor environments. Hot-swappable SFP+ connectors simplify installation and maintenance, while the copper construction delivers predictable short-distance performance and lower total cost of ownership for rack-level connections. Backed by StarTech’s lifetime warranty and multilingual technical support, the cable is intended for dependable, long-term use.

Suitable for

• In-rack switch-to-switch connections
• Server-to-switch direct links
• Short-distance storage array interconnects
• Optical port consolidation where fiber is not required

Key specifications

• Data rate: 10 Gbps
• Length: 1 m (approximately 3.3 ft)
• Connector type: SFP+ to SFP+ (Mini-GBIC form factor)
• Cable type: Passive Twinax copper
• Power profile: Low power, passive operation (no active electronics)
• Typical application: Short-reach, point-to-point 10GbE links
• Hot-swappable: Yes

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the devices to be interconnected, ensuring the latch engages. Because the cable is hot-swappable, it can be connected or removed while devices are powered on, but follow your equipment vendor’s procedures for link changes to avoid transient traffic impact. Verify that the connected devices are configured for 10GbE operation and that the ports accept passive Twinax assemblies or are set to auto-detect compatible SFP+ modules. After installation, check link status indicators and network management interfaces to confirm proper operation.

Usage recommendations

Use this direct-attach 1 m SFP+ cable for short, within-rack connections up to the specified length. Avoid routing the cable near sources of strong electromagnetic interference and ensure bend radius recommendations from equipment manufacturers are respected. For longer distances or where fiber is preferred for isolation or distance, select appropriate optical transceivers and fiber cabling instead.
