DAC Cable BlueLan PAN-QSFP-DAC-1M-BL QSFP QSFP InfiniBand 1m Black

The BlueLan PAN-QSFP-DAC-1M-BL is a 1 meter direct attach copper (DAC) cable with QSFP connectors on both ends, engineered for InfiniBand and high-speed networking environments. Its short length suits top-of-rack and server-to-switch connections where low latency and reliable signal integrity are required. The cable combines a compact black jacket with flexible construction to simplify routing in dense rack setups while providing a stable physical link between QSFP ports.

Advantages

This DAC cable delivers a low-latency, energy-efficient connection without the need for separate optical transceivers. With native QSFP-to-QSFP connectivity it reduces component count and simplifies deployment in data center switches, servers and storage systems. The 1 m length minimizes signal degradation and keeps cabling tidy in limited space installations. Its black outer jacket offers a discreet appearance and the cable’s light weight supports easy handling during installation or reconfiguration.

Suitable for

• Short-reach interconnects between QSFP ports in data centres
• Server-to-switch and switch-to-switch connections within racks
• High-throughput InfiniBand fabrics and low-latency clusters
• Dense cabling environments requiring flexible, compact links

Key specifications

• Cable type: Direct Attach Copper (DAC)
• Cable length: 1 m
• Connectors: QSFP to QSFP
• Weight: 0.15 kg
• Colour: Black

How to use

Ensure both devices support QSFP direct attach connections and power down or follow hot-plug guidance per device documentation before insertion if required. Align and insert each QSFP connector into the corresponding port until it clicks or seats fully, taking care not to bend the cable sharply. Verify link status via the host or switch management interface and perform any necessary port configuration for InfiniBand operation. To remove, release the connector latch and pull straight out without twisting.

Recommendations

Use the 1 m BlueLan PAN-QSFP-DAC-1M-BL for short interconnects inside racks to maintain low latency and stable signal performance. Avoid tight bends and excessive tensile force; follow equipment vendor guidelines for QSFP handling and hot-plug procedures to ensure longevity and reliable operation.
