Network Cable BlueOptics FN-CABLE-QSFP+1 QSFP DAC 1m Blue

The BlueOptics FN-CABLE-QSFP+1 QSFP DAC 1m Blue is a 1-metre direct attach copper (DAC) cable with QSFP connectors designed for short-range, high-speed interconnections. It provides a low-latency physical link for QSFP-enabled switches, servers and network appliances, supporting multi-lane data transfer and consistent signal integrity in dense rack environments. The blue jacket offers easy visual identification in cabling runs while the compact DAC form factor reduces the need for transceivers and simplifies deployment in data centers.

Advantages

The cable delivers reliable high-throughput connections with low power consumption compared with optical transceivers, offering a cost-effective solution for short distance links. Its factory-terminated QSFP ends ensure consistent performance and minimize installation errors. The robust outer jacket and strain-relief design increase mechanical durability and help maintain signal quality under frequent handling or cable re-routing.

Suitable for

• Server-to-switch connections within the same rack or adjacent racks
• Switch-to-switch links in top-of-rack or spine-leaf architectures
• Short-distance high-speed interconnects in data centers and telecom rooms
• Environments where low-latency, multi-lane QSFP connections are required

Key specifications

• Connector type: QSFP (Quad Small Form-factor Pluggable)
• Length: 1 meter
• Cable type: Direct Attach Copper (DAC)
• Color: Blue jacket for cable identification
• Usage: Short-reach, high-speed interconnects with multi-lane signaling
• Form factor: Compact, factory-terminated assembly

How to use

Install the DAC cable by inserting each QSFP connector into the corresponding QSFP port on your devices until the latch engages. Ensure ports are compatible with passive DAC assemblies and power down or follow hot-swap guidelines provided by your equipment vendor if required. Route the cable to avoid sharp bends and excessive strain; maintain the minimum bend radius specified by your rack or cabling best practices. Verify link status and speed in device management interfaces after connection.

Usage recommendations

Use this 1 m QSFP DAC for short-reach links inside racks or between adjacent racks. Keep cable runs tidy with proper cable management, avoid tight bends near connector heads, and match cable type to port specifications to ensure expected throughput and low latency.
