## Long description

Direct Attach Copper (DAC) cable CBO QSFP28-DAC-5M is a 5-meter twinax cable engineered for QSFP28 interfaces and listed as compatible with Gigamon equipment. The cable delivers a short-reach, low-latency wired connection for QSFP28 ports, offering a fixed copper alternative to optical transceivers for high-speed links within racks and across adjacent racks in data centers.
Advantages
This 5 m twinax DAC provides a reliable, energy-efficient connection with minimal signal conversion and low latency. Its one-piece construction eliminates the need for separate transceivers, reducing component count and simplifying installation. The cable supports high-bandwidth QSFP28 links while maintaining controlled impedance and signal integrity for short-reach interconnects.
Suitable for
Top-of-rack (ToR) switch to switch connections requiring QSFP28 ports
Server to network appliance links inside the same rack or adjacent racks
Data center short-reach high-bandwidth interconnects
Key specifications
Connector type: QSFP28 twinax (fixed copper DAC)
Cable length: 5 meters
Physical medium: Twinax copper
Typical use: Short-reach, high-speed (25 Gbps per lane aggregated to 100 Gbps)
Latency: Low, no optical-electrical conversion required
Installation: Hot-pluggable style connectors for QSFP28 ports
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on the devices to be linked, ensuring the connector latches engage to secure the connection. No additional configuration is required at the cable level; device-level settings such as port enabling, speed negotiation and VLAN or trunk configuration should be handled on the network equipment. Handle the cable by its connector housings and follow data center cable management practices to avoid sharp bends and undue mechanical stress.
Usage recommendations
For reliable operation, use this DAC cable for short-distance links up to 5 m within racks or between adjacent racks. Avoid routing near high-power electrical sources or placing under heavy bundles that could deform the twinax leads. Verify compatibility with the specific Gigamon or other vendor hardware and confirm port settings on both ends before deployment.
