## Summary description

CBO DAC Cable 100G-Q28-Q28-C-0501 is a 0.5 m direct attach copper (DAC) cable for 100G QSFP28 ports. Designed for short-reach high-speed connections between switches, servers and network appliances, it provides a low-latency, cost-effective link without optical transceivers. Blue jacket identifies the cable and simplifies rack management.

## Long description

CBO DAC Cable 100G-Q28-Q28-C-0501 100G QSFP28 Direct Attach Copper 0.5 m Blue is a short-reach copper interconnect designed for 100 Gigabit QSFP28 ports. The cable provides a direct electrical connection between compatible switches, servers and network appliances, delivering 100G data transfer rates with minimal latency. The 0.5 m length fits dense rack environments and the blue jacket simplifies identification and cable management in data centers.
Advantages
The direct attach copper design eliminates the need for separate optical transceivers, reducing component count and power consumption while keeping total link cost low. The QSFP28 connectors and assembly are engineered to support full 100G signaling with low insertion loss and predictable electrical performance. The short 0.5 m length minimizes signal degradation and is suited to top-of-rack and adjacent-rack connections. The colored jacket helps with visual organization and faster maintenance tasks.
Suitable for
Short-reach 100G connections between top-of-rack switches and servers
Interconnects in high-density rack environments
Patch connections between adjacent network appliances and storage systems
Data center links where power efficiency and cost-effectiveness are priorities
Key specifications
Interface: QSFP28 to QSFP28
Length: 0.5 m
Cable type: Direct Attach Copper (DAC)
Data rate: 100 Gbps
Connector gender: Plug-to-plug (copper assembly)
Jacket color: Blue
Typical use: Short-reach, within-rack or adjacent-rack interconnect
How to use
Plug each QSFP28 connector firmly into the corresponding QSFP28 port on your switch, server or appliance until the latch engages. Ensure both devices support passive DAC connections and are configured for 100G operation. Route the 0.5 m cable to avoid sharp bends; maintain manufacturer-recommended bend radius for copper assemblies. If replacing an active transceiver link, verify port settings and link status after installation to confirm the 100G link is established and stable.
Usage recommendations
Inspect connectors for debris or damage before installation, and avoid excessive bending or pulling on the cable. Use the blue jacket for consistent rack labeling and document the connection in your network inventory. For deployments requiring longer reach or optical isolation, consider active optical solutions instead of a DAC.
