Direct Attach Cable (DAC) CBO DAC-SFP-10G-5M 5 m SFP+ passive copper cable

CBO DAC-SFP-10G-5M is a 5 m SFP+ Direct Attach Cable (DAC) designed for short-reach 10 Gigabit Ethernet links between devices that have SFP+ ports. This passive copper twinax cable delivers low-latency, energy-efficient connectivity for switches, servers and storage systems, enabling straightforward rack-to-rack and within-rack connections without the need for separate optical transceivers. The integrated SFP+ connectors ensure a compact physical profile and plug-and-play operation in compatible network equipment.

Advantages

The passive SFP+ copper construction provides consistently low latency and reduced power consumption compared with active or optical interconnects. At 5 metres, the cable is long enough for common within-rack and adjacent-rack connections while keeping signal integrity high. The twinax design and fixed SFP+ plugs simplify installation and reduce points of failure by eliminating separate transceivers and fiber patching. Compatibility with standard SFP+ ports makes it a practical choice for dense data centre deployments and short-distance consolidation of network links.

Suitable for

• Rack-to-rack connections in data centres and server rooms
• Within-rack links between switches, top-of-rack devices and servers
• Short-reach uplinks between storage arrays and host interfaces
• High-density switch stacking and leaf-spine fabrics over short distances

Key specifications

• Connector type: SFP+ fixed plugs (female host-side compatibility)
• Length: 5 metres
• Data rate: 10 Gbps (10 Gigabit Ethernet).
• Medium: Passive copper twinax cable
• Latency: Low, suitable for latency-sensitive applications
• Power: Passive design, no external power required
• Typical use environment: Short-reach data centre and enterprise networking

How to use

Install by inserting each SFP+ connector into the SFP+ port of the devices to be linked, ensuring the latch engages securely. No additional configuration is required for basic connectivity; most switches and servers will recognise the passive SFP+ link automatically. Route the cable to avoid sharp bends and mechanical stress, keeping bend radius within manufacturer guidelines to maintain signal integrity. For best results, install while equipment is powered down or follow hot‑plug procedures recommended by the hardware vendor.

Recommendations

Use this 5 m passive SFP+ DAC where short physical distance and low latency are priorities. Confirm compatibility with your equipment vendor’s supported DAC list and ensure SFP+ port firmware accepts passive copper modules. Avoid exposure to excessive mechanical strain and install within the intended rack pathways to preserve performance and longevity.
