## Summary description

Passive DAC cable CBO QSFP28-DAC-5M, 5 meters long, designed for direct attach copper connections between QSFP28 ports. Provides short-reach, low-latency links for switches, routers and network appliances that support QSFP28 form factor. Suited for high-speed 100GbE interconnects in data centers and server racks, offering plug-and-play installation and reduced power consumption compared with active optics.

## Long description

The CBO DAC Cable QSFP28-DAC-5M is a 5-meter passive direct attach copper cable engineered for short-reach, high-bandwidth connections between QSFP28 ports. Designed for data center and rack-level interconnects, this BlueOptics cable supports 100GbE links with low latency and minimal power consumption compared with active optical assemblies. The plug-and-play form factor allows direct connection between compatible switches, routers and network appliances without additional transceivers.
Advantages
This passive direct attach copper cable delivers reliable 100GbE performance with low latency and reduced power usage. Its fixed 5 m length simplifies cable management in server racks and top-of-rack deployments, while the QSFP28 connectors ensure compatibility with devices that use the QSFP28 form factor. Because it is a passive solution, the cable does not require external power or additional configuration and offers predictable electrical characteristics for short-distance links.
Suitable for
 Short-reach 100GbE links between switches and routers in data centers
 Top-of-rack and end-of-row interconnects in server racks
 High-throughput, low-latency connections for storage arrays and network appliances
 Environments where reduced power consumption and plug-and-play installation are desired
Key specifications
 Form factor: QSFP28 to QSFP28
 Cable type: Passive direct attach copper (DAC)
 Supported data rate: 100 Gigabit Ethernet
 Length: 5 meters
 Latency: low, suitable for short-reach interconnects

 Installation: plug-and-play
How to use
Install the CBO QSFP28-DAC-5M by inserting each QSFP28 connector into the corresponding port on the devices to be linked. Ensure both ports support QSFP28 and are configured for 100GbE operation if required by the network equipment. Secure the cable connectors until they latch, and verify link status via the device management interface or indicator LEDs. No additional drivers or optical transceivers are necessary for standard direct attach connections.
Usage recommendations
For reliable performance, route the cable to avoid sharp bends and mechanical stress; maintain the specified 5 m length and avoid excess tension. Use this passive DAC for short-distance rack or row-level connections; for longer spans or optical isolation requirements, consider active optical solutions or fiber-based transceivers.
