## Summary description

Direct Attach Cable (DAC) CBO Arista CAB-Q-Q-100G-2.5 is a 100G high-speed passive cable designed for short-range connections between compatible switches, routers and network devices. It provides a fixed 100 Gigabit link for data center interconnects, reducing the need for transceivers. Ideal for rack-to-rack or within-rack connectivity where a reliable, low-latency 100G connection is required.

## Long description

Direct Attach Cable CBO Arista CAB-Q-Q-100G-2.5 is a passive 100G high-speed cable designed for short-reach links between compatible network devices. The cable provides a fixed 100 Gigabit connection suitable for data center interconnects, reducing the need for separate optical transceivers and simplifying rack-to-rack or within-rack cabling. Its design aims to deliver low latency and stable throughput for environments that require reliable high-density 100G links.
Advantages
This 100G direct attach cable offers a cost-effective alternative to active optical modules for short-distance links, lowering overall component and power costs. As a passive assembly, it reduces heat and energy consumption compared with powered transceivers and simplifies installation with plug-and-play connectivity. The cable is engineered to provide consistent performance for high-bandwidth applications while minimizing signal loss across short distances.
Suitable for
 Rack-to-rack 100G connections in data centers
 Within-rack uplinks between switches and routers
 Short-reach aggregation links in campus or enterprise networks
 High-density switch interconnects requiring low latency
Key specifications
 Nominal data rate: 100 Gigabit Ethernet
 Cable type: Passive direct attach assembly
 Connector type: Quad small form-factor pluggable (compatible 100G QSFP form factor)
 Optimized for short-reach, within-rack and adjacent-rack distances
 Designed for low latency and low insertion loss
How to use
Install the cable by inserting each connector into the matching QSFP port on the network devices until fully seated. Ensure both devices support 100G passive DAC connections and that port configurations match the intended link speed and duplex settings. Avoid sharp bends and excessive cable stress during routing. Monitor the link status via connected device management interfaces to confirm a stable 100G connection after installation.
Usage recommendations
For best results, use this passive 100G DAC for short-distance interconnects (within or between adjacent racks). Verify compatibility with the switch or router vendor and check firmware or port settings if link negotiation issues occur. Keep cable bends above the specified minimum bend radius and avoid routing near high-heat sources to maintain long-term signal integrity.
