10G SFP+ DAC Cable, Passive Direct Attach Copper Cable for Switches and Servers

Product Overview

The Luleey 10G SFP+ DAC Cable is a passive direct attach copper cable designed for short-distance 10Gbps Ethernet interconnection. It uses SFP+ connectors on both ends and transmits electrical signals directly through copper cable, providing a simple and cost-effective alternative to optical transceivers and fiber patch cables.

This 10G Direct Attach Cable is commonly used for connecting switches, servers, routers, firewalls, storage systems, NAS devices, and network appliances inside the same rack or nearby cabinets. Compared with 10G optical modules, a Passive DAC Cable usually offers lower power consumption, lower cost, and lower latency for short-reach links.

The Luleey SFP+ Copper Cable is available in multiple lengths, including 1m, 1.5m, 3m, 5m, and 7m, making it suitable for rack-level 10G interconnection, data center access, enterprise networks, home labs, and short-distance 10G uplinks.

Specifications

Why Choose a 10G SFP+ DAC Cable?

A 10G SFP+ DAC Cable is one of the most practical solutions for short-distance 10G network connections. It combines the SFP+ interface and copper cable into one ready-to-use assembly, so users do not need separate optical modules or fiber patch cords.

This makes DAC cable useful for:

• Reducing 10G link cost
• Simplifying rack cabling
• Lowering power consumption
• Reducing latency
• Connecting nearby SFP+ devices
• Building compact 10G home lab networks
• Creating reliable server and switch interconnection

For short links inside the same rack, a Luleey Passive DAC Cable is often more practical than using two optical modules and a fiber patch cable.

DAC Cable vs AOC Cable vs Optical Module

DAC, AOC, and optical modules can all be used for 10G links, but they are suitable for different deployment needs.

Choose a 10G SFP+ DAC Cable when the two devices are close to each other.

Choose a 10G AOC cable when the link distance is longer or when lighter cable routing is needed.

Choose optical modules and fiber patch cords when the project requires longer transmission distance or replaceable optical components.

Passive DAC Cable Length Notes

Passive DAC cable is best for short-distance SFP+ interconnection. The Luleey 10G SFP+ Cable is available in 1m, 1.5m, 3m, 5m, and 7m lengths.

For best results:

• Use shorter DAC cables when possible
• Avoid sharp bending
• Confirm SFP+ port compatibility
• Choose the correct length before ordering
• Use AOC or optical modules for longer links

Passive DAC is not designed for long-distance transmission. For longer cable runs, AOC or optical transceivers are usually better choices.

Compatibility Notes

Luleey can provide compatible coding for different switch, router, server, and network equipment platforms. Before ordering, please confirm the device brand and model to ensure correct recognition and stable operation.

Common compatibility options include Cisco, Huawei, MikroTik, Ubiquiti, Juniper, HPE-Aruba, Intel, Mellanox, Arista, Brocade, Extreme, H3C, ZTE, TP-Link, and General coding.

FAQ

What is a 10G SFP+ DAC Cable?

A 10G SFP+ DAC Cable is a direct attach copper cable with SFP+ connectors on both ends, used for short-distance 10Gbps network interconnection.

What is this 10G Direct Attach Cable used for?

It is used for switch-to-switch links, server-to-switch connections, NAS connections, router uplinks, firewall connections, storage networks, data center racks, enterprise networks, and home lab 10G upgrades.

Is this a passive DAC cable?

Yes. This is a passive copper DAC cable. It directly transmits electrical signals through copper wire without optical conversion.

What lengths are available?

Available lengths include 1m, 1.5m, 3m, 5m, and 7m.

What is the difference between DAC and AOC?

DAC uses copper cable and is best for short links. AOC uses optical fiber inside the cable assembly and is better for longer or lighter cable routing.

Do I need separate SFP+ modules?

No. The SFP+ connectors are built into the DAC cable, so separate optical modules are not required.

Is DAC better than optical modules?

For short-distance rack connections, DAC is often cheaper, lower power, and lower latency. For longer distances, optical modules are more flexible.

Can I use this cable with MikroTik or Ubiquiti devices?

Yes. Luleey can provide compatible options for MikroTik, Ubiquiti, Cisco, Huawei, Juniper, HPE-Aruba, Intel, Mellanox, Arista, ZTE, TP-Link, and other platforms.

Why choose Luleey 10G SFP+ DAC cables?

Luleey 10G SFP+ DAC cables provide low-cost, low-power, short-distance 10G interconnection with compatible coding options and factory-tested performance for switches, servers, routers, NAS devices, firewalls, and home lab networks.
