10G SFP+ to SFP+ Direct Attach Copper Cable
10G DAC (Direct Attach Cable) cable is a copper-based high-speed connection cable, mainly used for data transmission over short distances. It connects directly to device ports via integrated SFP+ connectors at both ends, eliminating the need for an optical-to-electrical conversion, thus simplifying the connection process and improving the stability and reliability of signal transmission. These cables are typically used for short-distance interconnections within a rack or between neighboring racks, with a maximum transmission distance of 7 meters.

FAQ About 10G DAC cable
A 10G DAC (Direct Attach Copper) cable is a twinaxial copper cable with SFP+ or QSFP+ connectors, used to connect devices like switches and servers in data centers. It seems likely that these cables are popular for their affordability and reliability over short distances, typically up to 10 meters.
✅ SFP+ to SFP+ interfaces
✅ Available in 0.5m to 7m lengths
✅ Passive and active versions✅ Plug-and-play with zero configuration
✅ Low power consumption (<0.5W)
✅ EMI shielding for reduced interference
Selecting the appropriate 10G DAC cable involves several considerations:
Cable length: Available from 0.5 to 10 meters; choose based on the distance between devices.
Connector types: Ensure compatibility with your equipment, typically SFP+ or QSFP+ connectors.
Device compatibility: Verify the cable works with your specific switches, routers, or servers by checking manufacturer specifications.
Passive vs. active: Passive cables are suitable for shorter distances (up to 7 meters), while active cables support slightly longer reaches with signal amplification.
Connectivity issues: Ensure connectors are securely plugged in. If problems persist, test with a different cable or port to isolate the fault.
Signal degradation or loss: Inspect the cable for physical damage or sharp bends. Replace damaged cables and avoid interference from nearby cables or electromagnetic sources.
Compatibility problems: Confirm the cable is compatible with your devices’ firmware and hardware, as mismatches can cause failures.
Feature | 10G DAC Cables | Optical Fiber Cables |
|---|---|---|
Cost | More affordable | More expensive |
Distance | Up to 10 meters | Up to several kilometers |
Power Consumption | Lower | Higher |
Use Case | Short-range (within racks) | Long-range (across buildings) |
Installation | Plug-and-play | May require transceivers |
10G DAC cables are preferred for short-distance, cost-sensitive applications, while optical fiber excels in long-distance scenarios.
10G DAC cables support data transmission speeds of up to 10 Gbps, making them suitable for 10 Gigabit Ethernet applications. Some cables may also support multi-rate communication (e.g., 1G to 10G), depending on the device.
10G DAC cables can be purchased from many network providers or online retailers, such as Fibrecross, a top supplier from China
