## Summary description

Passive copper DAC (direct-attach cable) CBO CABQ-S-3M is a 3-meter twinax direct-attach solution for short-range high-speed interconnects. Designed for direct connection between compatible network devices, it provides a cost-effective, low-latency link without transceivers. Suitable for rack-to-rack, switch-to-switch or server-to-switch links in data centers and enterprise networks.

## Long description

BlueOptics DAC cable CBO CABQ-S-3M is a 3 m passive copper direct-attach twinax cable engineered for short-range, high-speed interconnects in data centres and enterprise networks. The cable connects compatible switches, servers and storage devices directly without transceivers, offering a simple low-latency link suitable for top-of-rack, middle-of-row or rack-to-rack deployments. The 3 metre length provides flexibility for common rack layouts while maintaining signal integrity and predictable performance for short-reach connections.
Advantages
The passive twinax construction ensures low power consumption and minimal latency compared with optical links that require active transceivers. As a direct-attach solution, this cable reduces total hardware cost and simplifies installation by eliminating separate modules. Its fixed length and factory-terminated contacts provide consistent channel characteristics and ease of replacement or inventory management in dense server and switch environments.
Suitable for
Top-of-rack switch to server links
Switch-to-switch connections within the same rack or adjacent racks
Short-distance storage and SAN interconnects
High-density patching in datacentre rows
Key specifications
Type: Passive twinax direct-attach copper cable
Length: 3 metres
Connector style: Direct-attach factory-terminated contacts (compatible with matching SFP+/QSFP+ ports as supported by connected devices)
Signal medium: Copper twinax conductors
Typical use range: Short-reach interconnects within racks or between adjacent racks
Latency: Low, passive connection without on-cable electronics
How to use
Select ports on the two compatible network devices that support passive direct-attach copper connections. With devices powered down or following hot-plug guidelines from the hardware vendor, remove protective caps from the cable ends and insert each terminated connector into the corresponding port until it latches. Verify link LEDs or device management interfaces to confirm the connection. For removal, depress the connector latch and withdraw the cable straight out to avoid damaging ports.
Usage recommendations
Use this 3 m passive DAC for short, fixed-length connections inside racks or between neighbouring racks where low latency and cost-efficiency are priorities. Avoid routing the cable near high-power cabling or tight bends; maintain bend radii recommended by the equipment manufacturer. Confirm port compatibility and supported speeds on both devices before deployment to ensure reliable operation.
