StarTech 2m 10G SFP+ to SFP+ Direct Attach Twinax Cable (DAC) — 10Gbps, Passive, SFP+ Connectors

StarTech 2m 10G SFP+ to SFP+ Direct Attach Twinax Cable (DAC) is a 2-meter passive copper SFP+ cable engineered for short-range 10 Gigabit Ethernet links between switches, servers and network interface cards that accept SFP+ modules. The cable provides a low-power, low-latency physical connection for in-rack and data center interconnects, and is hot-swappable to simplify upgrades and maintenance. It is compatible with industry-standard MSA SFP+ ports and is offered with StarTech's lifetime warranty and multilingual technical support.

Advantages

The passive Twinax design delivers 10 Gbps throughput with reduced power consumption compared with active optical transceivers, making it suitable for short-distance, high-throughput links. Being a direct attach copper solution, the cable is a cost-effective alternative to fiber for in-rack connections and minimizes latency. Hot-swappable SFP+ connectors enable quick installation or replacement without powering down equipment. The product is tested for compatibility with Dell EMC and MSA-compliant SFP+ ports and is covered by a lifetime warranty and technical support from StarTech.

Suitable for

• Point-to-point in-rack connections between switches and servers
• Interconnects between NICs and top-of-rack switches for 10GbE
• Short-distance links inside data centers and server rooms
• Upgrades or replacements where low latency and low power are desired

Key specifications

• Data rate: 10 Gbps
• Cable type: Passive Twinax copper
• Connector type: SFP+ on both ends
• Length: 2 m (approximately 6.6 ft)
• Hot-swappable: Yes
• Typical use range: short-range / in-rack applications
• Compliance: MSA-compatible SFP+ interface
• Power profile: low-power passive operation

How to use

Ensure both network devices have active SFP+ ports and support 10GbE links. With devices powered on or off per your equipment vendor guidance, insert each SFP+ connector into the corresponding SFP+ port until it latches. Verify link status on both devices and confirm negotiated 10 Gbps operation through device management interfaces. For replacement, unplug the existing SFP+ connector by depressing the latch and pulling the module straight out, then insert the DAC in the same manner. No additional transceivers or fiber patching is required.

Usage recommendations

Use this passive 2 m DAC for short-distance, in-rack 10GbE connections where a low-cost, low-latency copper link is acceptable. Verify device compatibility with MSA SFP+ ports and check vendor compatibility lists if your environment requires vendor-specific validation. Avoid sharp bends and excessive strain on the cable and keep connectors clean when inserting or removing the cable.
