DAC kábel BlueLan PAN-QSFP-DAC-3M-BL QSFP QSFP InfiniBand 3 m čierny

The BlueLan PAN-QSFP-DAC-3M-BL is a direct attach copper (DAC) cable designed for short-range, high-bandwidth interconnects. With QSFP connectors on both ends and a 3 m length, this cable supports high-speed data transmission between InfiniBand-enabled devices and network equipment. Its compact design and black finish provide a discreet physical footprint in racks and cable trays while maintaining signal integrity and low latency for data center and high-performance computing environments.

Advantages

This DAC cable offers low latency and reduced signal loss characteristic of direct copper connections over short distances, providing reliable performance for high-throughput links. The QSFP-to-QSFP configuration ensures compatibility with devices that accept QSFP interfaces, and the fixed 3 m length simplifies cabling in dense rack deployments. The robust construction and standardized connectors reduce the need for active components, lowering power consumption compared with active optical alternatives.

Suitable for

• Connecting InfiniBand host adapters and switches
• Short-reach links inside server racks or between adjacent racks
• High-performance computing (HPC) clusters and data center interconnects
• Network environments requiring low-latency, high-bandwidth links

Key specifications

• Cable type: Direct Attach Copper (DAC)
• Length: 3 m
• Connectors: QSFP on both ends
• Typical use: Short-reach, high-speed interconnects
• Color: Black
• Weight (approx.): 0.25 kg

How to use

Install the cable by firmly inserting each QSFP connector into the corresponding QSFP port on your devices until the connector latches. Ensure devices are powered down or follow hot-plug procedures recommended by your equipment vendor before insertion or removal if applicable. Route the cable to avoid sharp bends and mechanical strain, maintaining the recommended bend radius for copper assemblies. Verify link status through device management interfaces or LEDs to confirm the connection is active.

Recommendations

For optimal performance, use this DAC cable for short-range connections within the same rack or adjacent racks. Avoid exceeding the specified bending radius and protect connectors from contamination when handling. Refer to your switch or host adapter documentation for supported cable types and firmware compatibility to ensure interoperability.
