## Summary description

Passive QSFP28 Direct Attach Copper cable from CBO, 5 meters long with male-to-male QSFP28 connectors supporting 100 Gbit/s. Designed for short-reach high-speed connections between network switches, routers or servers with QSFP28 ports. Provides a reliable, low-latency physical link for data center and server-rack interconnects where a fixed 5 m copper connection is required.

## Long description

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.
Usage 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.
