Cabo de cobre passivo DAC SFP+ CBO SFP-10G-DAC-0.5M 0,5 m, SFP+ Direct-Attach

CBO DAC SFP+ passive copper cable SFP-10G-DAC-0.5M is a 0.5 metre direct-attach copper link designed for SFP+ ports and 10 Gbps connections. Intended for short-reach interconnects in data centers and rack environments, the cable provides a compact, low-latency and energy-efficient alternative to optical transceivers. The assembly integrates fixed SFP+ connectors on both ends to simplify cabling between switches, routers and servers within the same rack or adjacent racks.

Advantages

The passive design reduces power consumption compared with active optical solutions and eliminates the need for separate transceivers and patch cords. With a half-metre length, the cable minimizes excess cabling in high-density racks and supports low-latency links suitable for server-to-switch and switch-to-switch connections. The fixed copper construction offers consistent electrical performance for short distances and requires no additional configuration.

Suitable for

• Short-reach connections between top-of-rack switches and servers
• Adjacent-rack interconnects where distance does not exceed 0.5 m
• Data center links requiring low latency and reduced power use
• Environments preferring direct-attach copper over optical transceivers

Key specifications

• Interface: SFP+ on both ends supporting 10 Gbps
• Length: 0.5 metre
• Type: Passive direct-attach copper cable (DAC)
• Use case: Short-reach, rack-level cabling
• Latency: Low, suited for latency-sensitive connections
• Power: No active electronics, reduced power consumption compared to optical modules

How to use

Insert each SFP+ connector into compatible SFP+ ports on networking equipment until the latch engages. Ensure both devices support passive SFP+ DAC links at 10 Gbps and that port settings match the intended link speed. For clean installation, route the cable to avoid sharp bends and secure it within the rack to prevent strain on connectors. No additional software or configuration is normally required beyond standard interface setup on the connected devices.

Recommendations

Verify compatibility with switch and server vendor documentation for passive SFP+ DAC support and recommended cable lengths. For reliable performance, avoid exceeding the specified 0.5 m length and protect the cable from excessive bending or mechanical stress during installation and maintenance.
