DAC-kabel CBO QTAPCABLE-2M 2 m QSFP Direct Attach Copper

CBO QTAPCABLE-2M is a 2 m Direct Attach Copper (DAC) cable with QSFP connectors engineered for short-range, high-speed interconnects between compatible network devices. The cable offers a fixed copper link that supports low-latency data transmission for QSFP ports, intended for use in data centers, network racks, and server rooms where concentrated, high-throughput connections are required. Its passive construction reduces power consumption compared with active optical modules and simplifies cabling for switch-to-switch, server-to-switch and appliance interconnects.

Advantages

The 2 m length and QSFP-to-QSFP connectivity provide a compact, reliable solution for short-reach links without the need for transceivers. As a direct attach copper cable, it delivers predictable latency and stable performance while avoiding the thermal and power overhead of active optics. The integrated connectors and robust cable jacket simplify installation and reduce the number of separate components required in dense rack environments.

Suitable for

• High-speed switch-to-switch connections within the same rack or adjacent racks
• Server-to-switch and appliance interconnects in data centers
• Temporary or permanent short-reach links in network racks and distribution panels

Key specifications

• Cable type: Direct Attach Copper (DAC), passive
• Connectors: QSFP to QSFP
• Nominal length: 2 m
• Use case: short-range high-speed interconnects
• Latency: low, fixed by copper medium
• Power profile: lower power consumption compared with active optical solutions

How to use

Insert each QSFP connector into the corresponding QSFP port on the devices to be linked, ensuring connectors are fully seated and the retaining latch is engaged if present. Route the cable in the rack to avoid tight bends and mechanical stress; maintain the minimum bend radius specified by the manufacturer to preserve signal integrity. For best results, verify link status and speed on both endpoints after connection and follow host device recommendations for QSFP port configuration.

Recommendations

Use the cable for short-distance, high-bandwidth links inside racks or between adjacent racks. Avoid exceeding the recommended bend radius and protect connectors from dust when ports are not in use. Choose passive DACs like this model when a cost- and power-efficient short-reach QSFP solution is required and when both endpoints support direct attach copper connections.
