Product Features
Technical Overview
This SFP28 DAC operates at a data transfer rate of 25 Gbit/s, supporting high-bandwidth applications such as server-to-switch links, storage area networks, and aggregation layer connectivity. The passive design eliminates the need for external power, reducing complexity and potential points of failure in your network infrastructure.
The cable uses 26/30 AWG copper conductors to ensure signal integrity over its 3.3-foot length, while the SFP28 connectors provide secure, hot-swappable connections to compatible SFP28 ports. This combination delivers a plug-and-play solution that maintains performance without the configuration overhead associated with optical modules.
Key Product Advantages
The UACC-DAC-SFP28-1M offers several distinct advantages for network administrators seeking reliable, high-speed interconnects. Its passive copper construction provides a simpler, more economical solution compared to active optical cables or separate transceivers with fiber patches, reducing both initial cost and ongoing maintenance.
Cost-Effective Performance
Delivers 25 Gb/s throughput without the expense of optical transceivers, making it ideal for budget-conscious deployments that require high-speed connections.
- Eliminates transceiver costs
- No separate power requirements
- Lower total cost of ownership
Simplified Deployment
The pre-terminated SFP28 connectors on both ends ensure quick installation and reduce the potential for connection errors compared to field-terminated solutions.
- Plug-and-play connectivity
- Consistent performance
- Reduced installation time
Durable Construction
Features a black PVC jacket that resists wear and tear in rack environments, while the copper conductors maintain signal integrity over the cable's 3.3-foot length.
- PVC jacket protection
- 26/30 AWG copper conductors
- Reliable signal transmission
Deployment / Use Cases
This SFP28 direct attach cable is specifically designed for short-reach connections within rack cabinets or between adjacent equipment. Its 3.3-foot length makes it perfect for top-of-rack switching scenarios where switches connect directly to servers or storage devices in the same or neighboring racks.
Common deployment scenarios include connecting Ubiquiti switches to servers in data center environments, establishing high-speed links between network aggregation devices, and creating backbone connections within server clusters. The cable's compatibility with network devices and switches ensures flexibility across various networking architectures.
Data Center Interconnects
Ideal for connecting servers to top-of-rack switches in high-density environments where 25 Gb/s throughput and minimal latency are critical for application performance.
Network Aggregation
Suitable for linking switches in stacked or distributed configurations, providing reliable 25 Gb/s uplinks that support growing network traffic demands.

FAQ
What is the maximum data transfer rate of this SFP28 cable?
The Ubiquiti UACC-DAC-SFP28-1M supports a data transfer rate of 25 Gbit/s (gigabits per second). This high-speed capability makes it suitable for bandwidth-intensive applications such as server connections, storage networks, and network aggregation links where traditional 10 Gb/s connections may be insufficient.
What devices are compatible with this direct attach cable?
This cable is compatible with network devices and switches that feature SFP28 ports. It's designed to work with Ubiquiti equipment and other vendors' devices supporting the SFP28 standard. The passive copper construction ensures broad compatibility without requiring specific driver or firmware support beyond basic SFP28 interface functionality.
What does 'passive' mean for this SFP28 cable?
Passive indicates that the cable does not contain active electronic components for signal amplification or retiming. It relies on the copper conductors to transmit signals over its 3.3-foot length without external power. This simplifies deployment, reduces potential failure points, and typically results in lower cost compared to active cables while maintaining full 25 Gb/s performance for short-reach applications.
What is the advantage of using a direct attach cable over separate transceivers?
Direct attach cables like the UACC-DAC-SFP28-1M provide a more cost-effective and simpler solution than using separate optical transceivers with fiber patch cables. They eliminate the need to purchase and manage two separate components (transceivers and fiber), reduce connection points that could fail, and typically offer lower latency since signals travel directly through copper rather than being converted to optical and back.
