Direct Attach DAC Cable CBO Force10 CBL-10GSFP-DAC-3 10Gbps, 3 m

The Direct Attach DAC Cable CBO Force10 CBL-10GSFP-DAC-3 is a 3 m passive copper twinax assembly engineered for 10Gbps SFP+ connections. Intended for short-reach links between SFP+ ports in switches, servers and storage arrays, this cable offers a straightforward, low-latency alternative to fiber transceivers. Its construction targets reliable high-speed connectivity in data centre top-of-rack and rack-to-rack deployments while keeping power consumption and overall link cost low.

Advantages

This 3 m direct-attach cable provides plug-and-play simplicity with minimal configuration required, delivering stable 10Gbps throughput and low latency for latency-sensitive applications. The copper twinax design reduces operational power compared with active optical options and eliminates the need for separate transceivers. Compatibility with standard SFP+ ports makes it a practical choice for consolidating short-distance connections in dense rack environments.

Suitable for

• Top-of-rack and rack-to-rack connections in data centres
• Direct server-to-switch or switch-to-switch high-speed links
• Storage area networks and SAN aggregation
• Environments where low latency and energy efficiency are priorities

Key specifications

• Data rate: 10 Gbps
• Connector type: SFP+ to SFP+
• Cable type: Passive copper twinax
• Length: 3 metres
• Typical use: Short-reach intra-rack and inter-rack links

How to use

Insert each SFP+ connector into compatible SFP+ ports on the devices to be linked, ensuring connectors are fully seated and locking mechanisms engage. No additional transceivers or fibre patch cords are required. Once connected, verify link status and speed through the host device interfaces or management tools; most systems will auto-negotiate the 10Gbps link. For best results, route the cable to avoid sharp bends and secure it to prevent strain on connectors.

Usage recommendations

Use this direct-attach cable for short-distance 10Gbps connections within racks or between adjacent racks. Avoid temperatures and environments outside device specifications, protect against mechanical stress, and confirm SFP+ port compatibility with your network equipment before deployment.
