Cavo SFP+ Direct Attach Copper (DAC) CBO CBL-205 5 m

Direct Attach Copper (DAC) SFP+ cable CBO CBL-205 5 m is a passive twinax copper cable designed for short-range 10 Gigabit Ethernet interconnects. Intended to connect SFP+ ports on switches, servers and storage devices, this 5 metre cable offers a fixed, low-latency physical link that does not require separate transceivers. The cable is optimized for rack-to-rack and top-of-rack connections in data centres and other networking environments where a reliable, energy-efficient copper link is preferred over optical modules for short distances.

Advantages

The DAC SFP+ cable provides low power consumption and minimal signal conversion since it is a direct copper link between SFP+ ports. Passive construction reduces complexity and cost compared with active optical transceivers and separate fiber modules. With a fixed 5 m length and standardized SFP+ form-factor connectors, the cable ensures predictable latency and stable throughput for 10 GbE traffic in short-range deployments. The twinax design offers robust electrical performance suitable for dense cabling inside racks.

Suitable for

• Rack-to-rack 10 Gigabit Ethernet connections in data centres
• Top-of-rack switch to server uplinks
• Interconnects between storage arrays and switches
• Short-range links where low latency and low power are required

Key specifications

• Interface: SFP+ compatible twinax connectors
• Length: 5 metres
• Data rate: 10 Gigabit Ethernet (10 GbE)
• Cable type: Passive copper twinax
• Typical use: Short-range, fixed copper interconnect

How to use

Insert the SFP+ connectors into the SFP+ ports of the network devices until the latches engage; ensure devices are powered down or support hot-plugging according to the equipment manual. Verify physical link lights and device configuration to confirm the 10 GbE link is active. Use standard network management tools to check link status, duplex and speed settings. For replacement or reconfiguration, carefully disengage the latch before removing the cable to avoid port damage.

Recommendations

Use the 5 m DAC SFP+ cable for short, fixed copper interconnects inside racks or between adjacent racks. Avoid running the cable alongside high-power electrical lines to reduce electromagnetic interference. Ensure compatibility with device SFP+ port specifications and verify that equipment supports passive DAC cables. For longer distances or where optical isolation is needed, consider optical transceivers and fiber cabling instead.
