Network Cable BlueOptics Mellanox ARZB-BL QSFP DAC 1m Blue

The BlueOptics Mellanox ARZB-BL QSFP DAC 1m Blue is a direct attach copper cable designed for short-range high-speed connections in data center and server environments. With a one-meter length and QSFP form factor, this DAC cable provides a straightforward point-to-point link between compatible QSFP ports, delivering low latency and full-duplex bandwidth suitable for high-performance switching and computing equipment. The blue jacket aids visual organization within rack and patching setups while the cable’s construction focuses on stable signal integrity for demanding workloads.

Advantages

This QSFP DAC cable offers low electrical latency and consistent throughput, which is important for latency-sensitive applications. The one-meter length reduces excess cable bulk in dense rack environments and supports clean airflow management. Durable connectors and shielding minimize signal degradation and help maintain reliable operation over repeated insertions and removals.

Suitable for

• Short-reach interconnects between QSFP-enabled switches and routers
• Direct links between servers and switches in data centers
• High-performance computing clusters requiring low-latency paths
• Top-of-rack and spine-leaf network architectures

Key specifications

• Form factor: QSFP direct attach copper (DAC)
• Length: 1 meter
• Color: blue jacket for easy identification
• Performance: designed for low latency and high bandwidth short-range links
• Connector type: QSFP compatible plug ends for direct mating
• Construction: shielded copper cable for signal integrity

How to use

Verify that both devices have compatible QSFP ports and that their firmware or configuration supports direct attach copper connections. Align each QSFP connector with the port and insert firmly until the latch engages. Route the cable to avoid sharp bends and to maintain required bend radius; secure it to prevent mechanical strain. Monitor link status on connected devices to confirm successful negotiation and expected link speed. For removal, depress the connector latch and withdraw straight out to avoid damaging the port.

Usage recommendations

Use the cable for short-distance links within racks or between adjacent racks. Keep the 1 m length free from tight bends, avoid placing heavy objects on the cable, and operate within the ambient temperature and handling specifications of the connected equipment. Replace the cable if connectors show physical wear or if link errors occur after troubleshooting.
