Cable Direct Attach Copper (DAC) CBO DAC-SFP-10G-0.5M-BL 0,5 m SFP+ 10 Gbit/s

CBO DAC-SFP-10G-0.5M-BL is a 0.5 m passive Direct Attach Copper (DAC) SFP+ cable that delivers 10 Gbit/s connectivity between SFP+ ports. Designed for short-distance server, switch and storage interconnections, this DAC cable provides a compact, low-latency physical link without the need for separate optical transceivers. The cable is intended for data centre and rack-to-rack environments where a fixed, cost-effective 10 GbE connection is required and space in patching areas is limited.

Advantages

The DAC cable offers a reliable, low-latency connection with simplified deployment because no transceivers are required. Its short 0.5 m length minimises signal loss and crosstalk for short-range links and reduces cabling clutter in dense rack layouts. As a passive SFP+ assembly, it consumes no additional power for signal conversion, making it an economical choice for high-density 10 Gbit/s interconnects.

Suitable for

• Short-range server-to-switch connections within a rack
• Switch-to-switch links for adjacent rack or top-of-rack deployments
• Storage array connections where 10 GbE is required and transceivers are not needed
• High-density patching areas in data centres requiring compact cabling

Key specifications

• Interface: SFP+ to SFP+ (direct attach copper)
• Length: 0.5 m
• Data rate: 10 Gbit/s
• Cable type: Passive copper twinax
• Typical use: Short-distance, rack-to-rack or intra-rack interconnects
• Latency: Low, suitable for time-sensitive links

How to use

Install the DAC cable by inserting each SFP+ connector into the corresponding SFP+ ports on your devices until the latch engages. Ensure both devices support passive SFP+ DAC connections and are powered off or follow hot-swap guidelines of your hardware during installation. Route the 0.5 m cable to avoid excessive bending; maintain manufacturer-recommended bend radius to prevent damage. After connection, verify link status and speed on both devices' network interfaces.

Recommendations

Use this 0.5 m passive DAC cable for short, fixed connections inside racks or between adjacent racks where a low-cost, low-latency 10 GbE link is required. Confirm hardware compatibility with passive SFP+ DACs and avoid tight bends or mechanical strain to preserve signal integrity and connector life.
