Overview

The QNAP CAB-DAC15M-SFPP is a 1.5-meter SFP+ 10GbE twinaxial direct attach cable designed to provide high-speed network connections between SFP+ equipped devices such as NAS units, managed switches, and servers. Direct attach cables offer a practical advantage over optical transceiver modules for short-distance links: they are less expensive, introduce lower latency, and require no separate transceivers or fiber patch cables. Simply plug each SFP+ connector into a compatible port and the link is established automatically.

At 1.5 meters, this cable is well-suited for connections within a single rack or between closely positioned equipment — a common scenario in small server rooms, home labs, and workgroup environments. The passive twinaxial copper construction draws no additional power and delivers consistent 10Gbps throughput. While QNAP manufactures this cable primarily for use with its own NAS and network products, SFP+ DAC cables generally adhere to industry-standard MSA specifications, making them broadly compatible. That said, it is always worth confirming compatibility with your specific switch or NIC vendor before purchasing.

Pros & Cons

👍 Pros

  • Lower cost than equivalent SFP+ optical transceiver and fiber cable setups
  • Passive design requires no external power and produces minimal latency
  • Plug-and-play operation with no drivers or software needed
  • 1.5-meter length suits typical rack-to-rack and in-rack connections

👎 Cons

  • 1.5-meter fixed length offers no flexibility for longer runs between racks
  • Limited to 10GbE speeds and not forward-compatible with 25GbE or higher SFP28 links
  • Twinaxial copper cable is stiffer and harder to route than thin fiber patch cables
  • Compatibility should be verified with non-QNAP switches and NICs before purchase

Frequently Asked Questions

The CAB-DAC15M-SFPP is designed for use with SFP+ 10GbE network interface cards and switches. While made by QNAP, SFP+ DAC cables following industry standards typically work with equipment from multiple vendors — check your device's compatibility list to confirm.
A direct attach cable (DAC) is a single passive cable with SFP+ connectors built into each end, eliminating the need for separate transceivers and fiber patch cables. This makes it simpler, more affordable, and lower latency for short-distance connections.
This cable is 1.5 meters (approximately 4.9 feet) long, which is typical for DAC cables designed for connections within the same rack or between adjacent equipment.
No. SFP+ DAC cables are plug-and-play — insert each end into an SFP+ port and the link negotiates automatically. No drivers, software, or power configuration is needed.
