SFP+ kabel BlueOptics SFP-10G-DAC-0.5M-AT-BL 0,5m samec/samec

The BlueOptics SFP-10G-DAC-0.5M-AT-BL is a 0.5 meter SFP+ direct attach cable (DAC) with SFP+ male connectors on both ends. As a passive twinax copper cable rated for 10GBase-CR, it provides a low-latency, low-power physical link for short-distance connections in racks and between adjacent racks. The cable follows MSA-compliant SFP+ interface definitions and supports common 10 Gbit/s protocols such as Ethernet, FCoE and Fibre Channel when used with compatible hardware.

Advantages

This 0.5 m DAC offers a compact, cost-effective solution for high-speed interconnects with minimal power consumption and reduced latency compared with active optical transceivers. The passive twinax construction and MSA-compliant SFP+ connectors ensure interoperability with major network platforms that support compatible passive DACs. Quality component selection and factory testing are used to achieve consistent performance and long service life suitable for data center deployments.

Suitable for

• Server-to-switch connections inside rack environments
• Switch-to-switch interconnects across adjacent racks
• High-throughput storage system links supporting Ethernet, FCoE or Fibre Channel
• Short-reach, low-latency links in data centers and network closets

Key specifications

• Connector type: SFP+ male to SFP+ male
• Length: 0.5 meter
• Data rate: up to 10 Gbit/s (10GBase-CR)
• Cable type: passive twinax copper (30 AWG)
• Compliance: MSA SFP+ electrical/mechanical interface
• Typical power consumption: very low (passive design, ~0.1 W system effect)

How to use

Insert each SFP+ connector into the SFP+ port of the two devices to be linked, ensuring proper seating and that the host hardware supports passive DACs. No external power or configuration is required for the cable itself; link negotiation and protocol settings are handled by the connected devices. Verify link status in the device management interface after installation to confirm a stable 10 Gbit/s connection.

Recommendations

For reliable operation, use this DAC within short rack-to-rack spans and on devices explicitly supporting passive SFP+ DACs. Avoid sharp bends and excessive strain on the cable; maintain bend radii recommended by the manufacturer and ensure ports are free of dust. When integrating into critical systems, confirm compatibility with the target switch or storage platform and consider requesting a test sample to validate interoperability before large-scale deployment.
