25G DAC 5M — A Cost-Efficient and Reliable Solution for High-Speed Short-Reach Connectivity

As data center architectures evolve toward higher bandwidth and lower latency, the demand for efficient and reliable short-reach interconnects continues to rise. The 25G Direct Attach Cable (DAC) 5-meter version has become a preferred choice for modern cloud, enterprise, and carrier-grade networks due to its stability, efficiency, and cost advantages.

1. What Makes 25G DAC 5M Essential for Today’s Data Centers?

The 25G DAC solution is designed for Top-of-Rack (ToR) and Middle-of-Rack (MoR) deployments, where short-distance, high-speed connections are critical. Unlike optical transceivers, DACs rely on a passive copper structure, delivering stable and low-latency performance without optical-to-electrical conversions.

Key Features

• 25Gbps high-speed performance for server, switch, and storage interconnect

• Passive copper design for lower heat and zero power consumption

• Multi-vendor compatibility (Cisco, Arista, Juniper, Dell, H3C, etc.)

• 5-meter optimized reach, ideal for rack-to-rack or adjacent-rack cabling

2. Solving Real Data Center Pain Points

✔ Lower Infrastructure Costs

Optical modules may increase deployment expenses in short-distance environments.
25G DAC 5M offers the same bandwidth at a significantly lower cost, making it ideal for large-scale data center rollouts.

✔ Enhanced Operational Stability

Copper DAC cables are highly resistant to EMI/EMC interference, ensuring stable signal integrity even in dense server environments.

✔ Simplified Maintenance and Deployment

With a true plug-and-play experience, DACs reduce installation time and eliminate optical cleaning, alignment, or calibration tasks.

✔ Energy Efficiency for High-Density Racks

Since DACs require no power, they contribute to better thermal management and help reduce power consumption in large data centers.

3. Typical Application Scenarios

The 25G DAC 5M is widely used in:

• Top-of-Rack (ToR) and Middle-of-Rack (MoR) Switch-to-Server connections

• Storage networks including NVMe and SAN

• Cloud and virtualization environments

• High-speed enterprise compute clusters

Its short but flexible length makes it ideal for structured cabling inside racks and between adjacent racks.
