Direct Attach Cable StarTech.com DAC-SFP-10G-3M 3m 10G SFP+ Twinax

The StarTech.com DAC-SFP-10G-3M is a 3 m passive Twinax direct-attach copper cable with SFP+ connectors on both ends, engineered for 10 Gigabit Ethernet (10GbE) connections. It is compatible with Dell EMC DAC-SFP-10G-3M ports and conforms to MSA industry standards. The cable is intended for short-distance, high-speed point-to-point links such as in-rack switch-to-switch or switch-to-server connections and offers a low-power, low-latency alternative to fiber for these applications.

Advantages

This passive SFP+ Twinax cable supports 10 Gbps data rates while consuming minimal power and delivering low latency, making it suitable for latency-sensitive network segments. It is hot-swappable to allow simple upgrades and replacements without prolonged network downtime. The cable provides a cost-effective solution for short-reach connections compared with fiber-optic transceivers and is built and tested to work with Dell EMC-compatible equipment. StarTech.com backs the product with a lifetime warranty and lifetime multilingual technical support.

Suitable for

• Short-distance 10GbE links in data centers and server rooms
• Point-to-point in-rack switch-to-switch connections
• Switch-to-server connections within the same rack or adjacent racks

Key specifications

• Length: 3 m (9.8 ft)
• Interface: SFP+ (Mini-GBIC) connectors on both ends
• Data rate: 10 Gbps (10GbE)
• Cable type: Passive Twinax direct-attach copper
• Compatibility: Designed and tested for Dell EMC compatible switches and routers; MSA compliant
• Power/latency: Low power consumption and low latency
• Warranty: Lifetime warranty from StarTech.com

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the two devices you wish to connect (for example, a switch and a server). The cable is hot-swappable, so it can be installed or removed while devices are powered on if supported by the equipment. Ensure compatible SFP+ ports and firmware settings on both ends to maintain link negotiation at 10 Gbps.

Usage recommendations

Use this 3 m passive DAC for short-reach 10GbE connections within the same rack or between adjacent racks. Verify device compatibility (Dell EMC or MSA-compliant devices) and firmware settings before deployment. For longer distances or when electrical isolation is required, consider using fiber-optic transceivers instead.
