SFP+ kabel BlueOptics SFPP-DAC-3M-SY-BL 3m samec/samec

The BlueOptics SFPP-DAC-3M-SY-BL is a 3 meter SFP+ direct attach cable (DAC) with male-to-male SFP+ connectors designed for short-range, high-speed 10G data links. As a passive twinax copper cable it conforms to SFP+ MSA electrical and mechanical interfaces and is intended for linking switches, routers, storage systems and other SFP+ ports within and between adjacent rack units. The cable supports 10GBase-CR electrical signaling over a 3 m distance and is built to provide reliable signal integrity and low latency for server and network interconnects.

Advantages

The cable delivers low power consumption and very low latency typical of passive SFP+ twinax solutions, while providing a cost-effective alternative to optical transceivers for short runs. Manufacturing follows MSA-compliant dimensions and electrical characteristics to ensure interoperable operation with major hardware platforms that support SFP+ passive DACs. The construction uses high-quality components and 30 AWG twinax conductors to maintain signal quality over the specified 3 m length.

Suitable for

• Interconnects between switches and routers within racks and across adjacent racks
• Server-to-switch and storage-to-switch 10G connections
• High-density data centre top-of-rack cabling for short distances
• Environments where low latency and low power consumption are required

Key specifications

• Length: 3.0 meters
• Connector type: SFP+ male to SFP+ male
• Cable type: Passive twinax copper (DAC)
• Wire gauge: 30 AWG
• Supported data rate: up to 10 Gbit/s
• Compliance: SFP+ MSA electrical and mechanical compatibility

How to use

Install the cable by inserting each SFP+ plug into the corresponding SFP+ port until the latch engages. Ensure both connected devices support passive 10GBase-CR DAC operation. Route the cable to avoid sharp bends and mechanical stress; maintain the specified 3 m maximum run for guaranteed performance. No external power or configuration is required for the passive DAC itself—link configuration is handled by the connected devices according to their networking settings.

Recommendations

For best performance, use the cable for short-range 10G links up to 3 meters between compatible SFP+ ports, avoid tight bends and heavy compression, and verify device compatibility with passive SFP+ DACs. If in doubt, test connectivity in your environment before large deployments.
