Tecowin SFP-H10GB-CU3M-C Cisco 10GBASE-CU SFP+ Direct Attach Copper Cable, 3m, Passive Twinax, 10Gbps

For high-density 10 Gigabit Ethernet links where latency and power draw must stay minimal, this Tecowin SFP-H10GB-CU3M-C direct attach copper cable delivers a dependable 3-meter interconnect. Unlike optical modules that require separate transceivers and fiber, this passive twinax assembly integrates the SFP+ connectors directly onto shielded copper, cutting cost and complexity while preserving signal integrity.

Highlights

• Passive 10GBASE-CU twinax cable, 3 meters (9.84 ft), 30 AWG conductors
• Dual SFP+ connectors, hot-swappable, compatible with Cisco and MSA-compliant ports
• Ultra-low latency and <0.5 W power consumption per end for efficient rack deployments
• 100 Ohm impedance with full EMI/RFI shielding for stable 10 Gbps throughput
• RoHS, CE, and FCC compliant; PVC jacket rated for 0°C to 70°C operating range

In daily use

This DAC cable is ideal for top-of-rack switching, server-to-switch uplinks, and storage area networks. The passive design requires no additional power or signal conditioning, making it a plug-and-play solution for short-reach connections inside a cabinet or between adjacent racks. The 30 AWG twinax construction offers a slim profile that improves airflow and simplifies cable management in dense environments. Because it is hot-swappable, you can insert or remove the cable without powering down the connected equipment, reducing maintenance windows.
