Cable DAC CBO para Dell Mellanox 470-ACBY 1 m QSFP cobre de conexión directa

Inline direct-attach copper (DAC) cable CBO compatible with Dell Mellanox model 470-ACBY. This 1 m QSFP direct-attach cable is intended for short-reach connections between servers, switches and storage systems in data centers and network racks. The cable supports QSFP ports and provides a low-latency, power-efficient physical link for high-speed interconnects with compatibility dependent on the connected devices' supported data rates.

Advantages

The DAC cable offers a compact, pre-terminated connection that eliminates the need for transceivers, reducing power consumption and simplifying installation. With a 1 m length and QSFP connectors it minimizes signal loss for short runs and reduces rack clutter. The metal-shielded copper construction ensures consistent electrical performance and reliable grounding for 40/56/100 Gbps-capable QSFP interfaces where supported by the host hardware.

Suitable for

• Short-reach server-to-switch connections in data centers
• Interconnects between switches inside the same rack or adjacent racks
• High-performance computing clusters and storage array links
• Environments prioritizing low latency and reduced power consumption

Key specifications

• Cable type: Direct-attach copper (DAC), pre-terminated
• Connector type: QSFP on both ends
• Length: 1 m
• Data rates: Compatible with 40 Gbps / 56 Gbps / 100 Gbps QSFP links depending on device support
• Shielding: Metal-shielded copper for EMI protection and grounding
• Use case: Short-reach, rack-level and adjacent-rack interconnects

How to use

Connect each QSFP connector to the corresponding QSFP port on your servers, switches or storage devices. Ensure both endpoints support the intended data rate (40/56/100 Gbps) and are powered off or in a hot-pluggable state according to your equipment's guidelines before insertion. Insert the connector until it latches; verify link status through the device management interface. For removal, release the latch mechanism and pull the cable straight out to avoid damaging the connector or port.

Recommendations

For optimal performance place the cable in rack topologies that require short runs (up to 1 m), avoid tight bends and excessive pulling force, and route away from sources of strong electromagnetic interference. Confirm compatibility with your networking equipment firmware and port configuration to ensure full support of higher data rates.
