DAC Cable CBO QSFP Direct Attach CAB-Q-Q-2M 2 m, passive copper, QSFP+ to QSFP+

CBO DAC Cable CAB-Q-Q-2M is a 2-meter passive copper direct attach cable with QSFP+ connectors on both ends, designed for short-range, high-bandwidth links between QSFP or QSFP+ ports. The assembly provides a simple, low-latency physical connection without separate transceivers, intended for data center topologies, server-to-switch and switch-to-switch interconnects where distances are within a rack or between adjacent racks.

Advantages

The passive copper construction delivers low latency and energy-efficient connectivity compared with active optical solutions for short runs. With QSFP+ to QSFP+ connectivity, the cable supports high aggregate throughput while keeping installation straightforward—no additional modules or fiber patching are required. The fixed 2 m length reduces clutter and ensures predictable signal integrity for short-distance links in dense networking environments.

Suitable for

• Short-range interconnects within racks and between adjacent racks
• Server to top-of-rack switch connections using QSFP/SFP cages
• High-bandwidth switch-to-switch links in data center aggregation layers
• Environments where low latency and reduced power consumption are priorities

Key specifications

• Connector type: QSFP+ to QSFP+
• Cable type: Passive copper direct attach (DAC)
• Length: 2 meters
• Intended use: Short-range, high-bandwidth interconnects
• Typical benefits: Low latency, low power consumption for short links

How to use

Install the cable by inserting each QSFP+ connector into matching QSFP or QSFP+ ports on the devices to be linked, ensuring the connectors click into place and the latch engages. Verify that both networking devices recognize the link and that port configurations match expected speed and lane mapping. For safe handling, avoid sharp bends near the connector heads and route the cable to prevent physical strain on ports.

Usage recommendations

Use this passive 2 m DAC cable for connections where distance does not exceed the specified length and where passive copper assemblies meet performance requirements; for longer distances or when optical isolation is required, consider active copper or optical transceivers and fiber cabling.
