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

The CBO SFP+ Direct Attach Cable SFP-10G-DAC-0.5M-NA-BL is a 0.5 metre passive twinax cable engineered for 10 Gbps links between SFP+ ports on switches, servers and network appliances. It provides a short-range, low-latency physical connection intended for top-of-rack, uplink and rack-to-rack interconnects where a compact, power-efficient direct attach solution is required. The cable is compatible with standard SFP+ form-factor ports and is suitable for environments that prioritize minimal latency and reduced power consumption.

Advantages

This 0.5 m SFP+ DAC delivers 10 Gbps throughput with minimal signal loss and negligible latency compared with optical transceivers. As a passive twinax assembly it requires no additional power or optics, reducing operational cost and complexity. The fixed length simplifies cable management in dense rack installations and supports reliable short-reach connectivity between network devices while maintaining SFP+ mechanical and electrical compatibility.

Suitable for

• Top-of-rack uplinks between switches and aggregation devices
• Server-to-switch connections in data centres and server rooms
• Rack-to-rack interconnects within the same rack row
• High-performance short-reach links requiring low latency

Key specifications

• Connector type: SFP+ on both ends
• Length: 0.5 metre
• Maximum data rate: 10 Gbps
• Cable type: Passive twinax direct attach
• Use case: Short-range copper interconnect for SFP+ ports

How to use

Plug each SFP+ connector into the corresponding SFP+ port on your network devices until the connector latches. Ensure both devices support passive SFP+ direct attach cables and that firmware or compatibility restrictions are addressed according to device vendor documentation. No transceiver modules or additional power sources are required. For best results, route the cable to avoid sharp bends and maintain the specified bend radius to preserve signal integrity.

Recommendations

Verify device compatibility with passive SFP+ DACs before deployment and check port firmware updates if link negotiation issues occur. Use the 0.5 m length where short, direct connections are needed to reduce clutter and power consumption; for longer spans choose an appropriate alternative such as active DAC or optical transceivers.
