Network Cable BlueOptics A1DQ DAC QSFP SC252501K3M30 A1DQ-BL BlueLAN 3m Blue

The BlueOptics A1DQ DAC QSFP SC252501K3M30 is a 3 meter direct attach copper (DAC) network cable with QSFP connectors designed for short-reach, high-speed interconnects. It provides a factory-terminated twin-ax copper solution that supports low-latency, high-bandwidth links between switches, routers and servers in data center and enterprise environments. The cable's construction is intended to ensure consistent electrical performance and mechanical robustness for rack-to-rack and within-rack connections.

Advantages

This BlueOptics DAC cable offers a compact, low-power alternative to active optical modules for short-distance links, delivering predictable latency and stable throughput. Its QSFP terminations enable straightforward integration into compatible 4-lane QSFP ports, and the pre-terminated design reduces installation time and the potential for termination errors. The cable's shielding and build quality are aimed at minimizing signal degradation and providing reliable operation in dense cabling environments.

Suitable for

• Inter-switch links in data centers
• Server-to-switch connections within racks
• High-bandwidth, low-latency clustering and storage networks
• Short-reach connections where optical transceivers are not required

Key specifications

• Connector type: QSFP to QSFP twin-ax copper
• Length: 3 meters
• Form factor: Direct attach cable (passive DAC)
• Usage: Short-reach, high-speed interconnects
• Physical: Shielded twin-ax construction for reduced interference

How to use

Install the cable by seating each QSFP connector into compatible QSFP ports on networking equipment until the retention latch engages. Ensure both ends are fully inserted and that the connected devices support DAC attachments and the intended link speed. Route the cable to avoid tight bends and mechanical strain; maintain the minimum bend radius recommended by the equipment vendor. After installation, verify link status and performance through the switch or server management interface.

Usage recommendations

Use this cable for short-distance, high-throughput connections inside racks or between adjacent racks. Avoid exposure to excessive heat or fluids, and prevent repeated tight bending or kinking to preserve signal integrity and cable lifespan.
