DAC cable CBO MCP1600-C005E26L 5 m QSFP28 direct-attach copper

Direct-attach copper (DAC) cable CBO MCP1600-C005E26L 5 m QSFP28 direct-attach copper is a 5-meter, high-speed copper assembly designed for direct QSFP28 port connections. It delivers a plug-and-play physical link for short-range, high-bandwidth data transmission between compatible switches, servers and network adapters. The cable is intended for onsite data center interconnects where low latency and reliable throughput are required within racks or between adjacent racks.

Advantages

This QSFP28 DAC cable provides a cost-efficient, power-saving alternative to optical transceivers for short distances, eliminating the need for separate SFP modules and fiber patching. The fixed-copper assembly offers low latency and stable performance with minimal configuration, and the 5 m length is suitable for rack-to-rack or within-rack installations. Its direct-attach design simplifies installation and reduces points of failure compared with multi-component links.

Suitable for

• High-bandwidth interconnects between top-of-rack switches and aggregation switches
• Server to switch connections in data center racks
• Short-distance uplinks and spine-leaf fabrics in closed data center environments
• Environments where low latency and consistent throughput are required

Key specifications

• Connector type: QSFP28 to QSFP28 direct-attach copper
• Length: 5 m
• Supported link speed: 100 Gbps (QSFP28)
• Media: Twinax copper cable assembly
• Form factor: Fixed direct-attach cable for QSFP28 ports
• Typical use range: Short-reach, within-rack or adjacent-rack connections

How to use

Insert each QSFP28 connector into the corresponding QSFP28 ports on the network devices until the latch engages. Ensure both devices are powered and compatible with QSFP28 direct-attach copper connections. No additional transceivers or fiber patch cords are required. Verify link status through device indicators or management interfaces and confirm the negotiated speed and lane configurations in the device settings. For safe removal, disengage the connector latches and withdraw the cable straight out to avoid stressing connectors or ports.

Recommendations

Use the cable for short-range interconnects inside racks or between adjacent racks; avoid routing over long ceilings or through conduits that may kink or excessively bend the twinax assembly. Keep bend radius within manufacturer guidelines, avoid sharp bends near connectors, and ensure proper airflow and cable management to maintain performance and reduce strain on QSFP28 ports.
