Cavo DAC BlueLan PAN-QSFP-DAC-2M-BL QSFP QSFP InfiniBand 2 m nero

The BlueLan PAN-QSFP-DAC-2M-BL is a 2-meter Direct Attach Copper (DAC) cable with QSFP connectors on both ends, intended for InfiniBand and high-speed networking applications. Designed by BlueOptics, this black, lightweight cable provides a short-range, high-bandwidth link between QSFP ports in data centers and high-performance computing racks. Its construction prioritizes signal integrity and low latency for reliably handling clustered storage, compute nodes, and switch-to-switch connections.

Advantages

This DAC cable offers a cost-effective and energy-efficient way to connect QSFP ports without the need for transceivers. Its short 2 m length reduces signal loss and maintains high throughput for InfiniBand environments. The cable's durable outer jacket and secure QSFP terminations ensure stable mechanical and electrical performance under typical data center installation conditions.

Suitable for

• Interconnecting QSFP-enabled switches and routers
• Direct server-to-switch or server-to-server connections in HPC clusters
• Short-reach InfiniBand links inside racks or between adjacent racks
• Environments where low latency and high bandwidth are required

Key specifications

• Cable type: Direct Attach Copper (DAC)
• Length: 2 m
• Connectors: QSFP to QSFP
• Application: InfiniBand and high-speed networking
• Colour: Black
• Weight: 0.15 kg

How to use

Install the PAN-QSFP-DAC-2M-BL by aligning each QSFP connector with the device's QSFP port and inserting until the latch engages. Ensure both connected devices are powered down or support hot-plugging according to the equipment manufacturer's instructions. Verify link status in the devices' management interface after connection. For best performance, avoid sharp bends and keep the cable free from tight cable ties or compressive forces.

Recommendations

Use this 2 m DAC cable for short-distance, high-bandwidth links in racks and adjacent rack connections. Avoid deploying it for long-distance runs; select appropriate active optical or long-reach options for extended links. Follow data center grounding and routing practices to maintain signal integrity and prevent mechanical strain on QSFP connectors.
