DAC Cable BlueLan PAN-QSFP-DAC-5M-BL QSFP QSFP 5m Black

The BlueLan PAN-QSFP-DAC-5M-BL QSFP QSFP 5m Black is a direct-attach copper (DAC) cable engineered for high-performance networking and InfiniBand environments. At 5 meters length and with QSFP connectors on both ends, it provides a stable, low-latency link between switches, servers and high-speed adapters in data centers and rack-level topologies. The cable is finished in black and is intended for short-reach, high-bandwidth connections where signal integrity and physical durability are required.

Advantages

This DAC cable delivers reliable electrical connectivity with minimal latency and predictable performance typical for QSFP-to-QSFP direct-attach solutions. Its fixed 5 m length simplifies cable management in rack installations and reduces the need for active optical transceivers. The construction balances signal integrity and mechanical robustness while keeping power consumption low compared with active optical alternatives.

Suitable for

• Interconnecting QSFP ports on switches and routers within the same rack or adjacent racks
• Linking servers and network adapters in high-performance computing and InfiniBand clusters
• Short-reach, high-bandwidth uplinks in data center top-of-rack or aggregation layers

Key specifications

• Cable type: Direct-attach copper (DAC)
• Connector type: QSFP to QSFP
• Length: 5 m
• Colour: Black
• Weight: 0.44 kg

How to use

Install the PAN-QSFP-DAC-5M-BL by inserting the QSFP connectors into compatible QSFP ports on the devices to be connected, ensuring the latch mechanism engages to secure each end. Ensure both ends are fully seated and that connected devices are powered down or perform a hot-swap according to the host device guidelines. Verify link status through the network equipment interface and monitor for stable link negotiation before transferring production traffic.

Recommendations

Use the cable for short-distance, high-bandwidth links; avoid bending the cable sharply and maintain recommended bend radius. Keep the cable away from sources of strong electromagnetic interference and follow equipment vendor guidelines for QSFP direct-attach connections and compatibility.
