Direct Attach Cable (DAC) CBO SFP-10G-DAC-0.5M-HU-BL 0.5 m SFP+ Male to Male 10 Gbit/s

CBO SFP-10G-DAC-0.5M-HU-BL is a 0.5 m passive Direct Attach Cable (DAC) with SFP+ male connectors on both ends, engineered for short-range 10 Gbit/s connections. The cable is intended for direct server-to-switch, switch-to-switch or storage interconnects in data center racks and network cabinets where short copper links provide a reliable, low-latency alternative to optical transceivers and fiber patch cords.

Advantages

The passive SFP+ DAC delivers 10 Gbit/s throughput with minimal latency and reduced power consumption compared with active optics. Its fixed 0.5 m length and SFP+ male-to-male termination ensure predictable signal integrity in tight rack deployments. The copper construction eliminates the need for separate transceivers, lowering cost per link and simplifying inventory. The cable’s compact form factor supports dense port configurations and straightforward hot-plug installation.

Suitable for

• Short-range 10GbE connections between servers and top-of-rack switches
• Switch-to-switch uplinks inside the same rack or adjacent racks
• Storage array connections requiring low-latency links
• Environments where cost-effective, low-power interconnects are preferred over optical solutions

Key specifications

• Connector type: SFP+ male to SFP+ male
• Link technology: Passive Direct Attach Copper
• Maximum data rate: 10 Gbit/s
• Length: 0.5 metres
• Typical applications: 10 Gigabit Ethernet, Fibre Channel short-reach
• Form factor: Low-profile, compact cable for dense port layouts

How to use

Install the cable by inserting each SFP+ connector into compatible SFP+ ports until the retention latch engages. Ensure both devices support passive SFP+ DACs and are powered off or follow hot-swap guidelines recommended by the equipment manufacturer when connecting live. Route the 0.5 m cable to avoid sharp bends or crushing; maintain gentle curves to preserve conductor integrity. After installation, verify link establishment and correct speed/duplex settings via the host or switch management interface.

Recommendations

Use this 0.5 m passive DAC for short, direct connections inside racks or between adjacent racks. Avoid exceeding recommended bend radius, and confirm compatibility with vendor equipment to ensure proper link negotiation and performance. For longer runs or environments requiring optical isolation, select fiber transceivers and patch cables instead.
