Cabo DAC BlueLan PAN-QSFP-DAC-0.5M-BL QSFP QSFP InfiniBand 0,5 m preto

The BlueLan PAN-QSFP-DAC-0.5M-BL is a direct attach copper (DAC) cable with QSFP connectors on both ends, designed for short-reach, high-speed links in data centers and network racks. With a 0.5 m length and InfiniBand support, this cable provides low-latency connectivity between compatible QSFP ports while maintaining a compact profile and durable black jacket suitable for dense cabling environments.

Advantages

This DAC cable delivers low latency and stable signal transmission for short-distance interconnects. The QSFP-to-QSFP connectors enable straightforward cabling between switches, servers and storage adapters without additional transceivers, reducing power consumption and component count. The 0.5 m length minimizes cable slack and improves airflow in racks, and the robust construction ensures reliable mechanical and electrical performance over sustained use.

Suitable for

• Interconnecting QSFP ports on switches and servers in data centers
• High-performance computing (HPC) clusters using InfiniBand
• Short-reach links inside server racks and top-of-rack setups
• Direct cabling between storage controllers and host adapters

Key specifications

• Cable type: Direct attach copper (DAC)
• Cable length: 0.5 m
• Connectors: QSFP to QSFP
• Protocol support: InfiniBand (short-reach)
• Color: Black
• Weight: 0.15 kg

How to use

Install the BlueLan PAN-QSFP-DAC-0.5M-BL by aligning each QSFP plug with the corresponding QSFP port on your switch, server or adapter and inserting until the connector latches. Ensure both ends are fully seated and that connected equipment is powered off or hot-swap capable according to vendor guidelines. After connection, verify link status and negotiated speeds in the device management interface. For InfiniBand configurations, confirm subnet manager and fabric settings as required.

Recommendations

Use this 0.5 m DAC cable for short, internal rack connections where low latency and minimal power draw are priorities. Avoid sharp bends and excessive strain on the cable; maintain recommended bend radius and secure cables to prevent mechanical stress. Verify compatibility with your QSFP ports and firmware, and follow equipment vendor guidelines for hot-plug procedures and supported link speeds.
