CBO QSFP28 Direct Attach Cable 5 m, Male-to-Male, 100 Gbit/s

CBO QSFP28 Direct Attach Cable 5 m, Male-to-Male, 100 Gbit/s is a passive copper interconnect from BlueOptics designed for short-reach, high-bandwidth links. The 5-meter cable terminates in QSFP28 male connectors on both ends and supports 100 Gbit/s aggregated data rates. It provides a fixed, low-latency physical connection suitable for linking network switches, routers, or servers equipped with QSFP28 ports in data center and server-rack environments.

Advantages

The cable offers a cost-effective, low-power connection method compared with active optical modules and transceivers. Its passive design reduces complexity and heat generation while delivering consistent signal integrity for short-distance 100 Gbit/s links. The integrated QSFP28 male connectors ensure mechanical compatibility with standard QSFP28 ports and simplify installation without additional transceivers.

Suitable for

• Short-reach 100 Gbit/s links between top-of-rack or spine switches
• Server-to-switch or switch-to-switch interconnects in rack environments
• High-density data center cabling where fixed copper links are acceptable

Key specifications

• Form factor: QSFP28 male-to-male connectors
• Length: 5 meters
• Nominal data rate: 100 Gbit/s
• Cable type: Passive direct attach copper (DAC)
• Use case: Short-reach, rack-level interconnects

How to use

Insert each QSFP28 male connector into the corresponding QSFP28 port on network equipment until the connector latch engages. Ensure both devices are powered and that the port settings on switches or servers are configured for 100 Gbit/s operation if manual configuration is required. Routine checks of connector seating and cable routing help maintain signal quality and avoid mechanical strain at the ports.

Recommendations

Route the cable to avoid sharp bends and mechanical stress; maintain minimum bend radius as recommended for copper DACs. Use in ambient temperatures and rack conditions appropriate for data center equipment. Verify compatibility with equipment vendor QSFP28 port specifications before deployment.
