## Summary description

Direct Attach Cable (DAC) BlueOptics CBL-0138-BL is a 3-meter 10GBASE-CR copper twinax cable for short-range 10 Gigabit Ethernet connections. Designed for direct server-to-switch or switch-to-switch links, it provides a passive copper connection with SFP+ form-factor compatibility, low latency and simple plug-and-play installation in data center and rack environments.

## Long description

BlueOptics Copper Direct Attach Cable 10GBASE-CR, 3 m, is a passive copper twinax cable engineered for short-range 10 Gigabit Ethernet links. With SFP+ form-factor compatibility, this 3‑metre 10GBASE-CR cable connects servers, switches or storage devices in rack and data centre environments. It offers a low-latency, plug-and-play copper connection intended for point-to-point links where fibre transceivers are not required.
Advantages
The cable provides a cost-effective, energy-efficient alternative to optical modules for short distances, delivering predictable signal performance and minimal configuration effort. Its SFP+ form-factor ends ensure compatibility with standard 10GbE SFP+ ports, while the passive twinax design reduces power consumption compared with active copper solutions. The fixed 3 m length simplifies cable management in racks and reduces the need for additional transceivers or adapters.
Suitable for
 Server-to-switch or switch-to-switch 10 GbE links in racks
 Short-range connections inside data centres and network closets
 Top-of-rack or middle-of-row connectivity where 3 m reach is sufficient
 Environments requiring low-latency, direct attach copper connections
Key specifications
 Standard: 10GBASE-CR (10 Gigabit Ethernet over copper)
 Length: 3 m
 Connector form factor: SFP+ compatible twinax
 Cable type: Passive copper twinax
 Use case: Short-range, direct-attach point-to-point links
How to use
Install the cable by inserting each SFP+ form-factor connector into the SFP+ ports of the two devices to be linked, ensuring secure seating and latch engagement. No additional configuration or transceivers are required for standard 10 GbE ports that support direct-attach copper. Verify link status on both devices after insertion and manage the cable within rack trays or ties to avoid undue strain on connectors.
Usage recommendations
Use this 3 m direct attach cable for short, fixed-length connections inside racks. Avoid tight bends and excessive tension near the connectors, and ensure both endpoints support passive SFP+ direct-attach copper to guarantee compatibility and link stability.
