Cabo SFP+ BlueOptics SFP-STACK-KIT-BL 1 m macho/macho

The BlueOptics SFP-STACK-KIT-BL 1m Male/Male is a 1 metre SFP+ direct attach cable (DAC) designed for short-distance, high-speed connectivity between SFP+ ports. As a passive 10GBase-CR twinax copper cable with SFP+ connectors on both ends and 30 AWG wiring, it is intended for linking hardware in racks and adjacent racks in data centres and enterprise networks. The cable supports 10 Gbps electrical signal transmission for applications such as Ethernet, FCoE and Fibre Channel where the connected equipment explicitly supports passive SFP+ DACs.

Advantages

This direct attach cable provides a compact, low-latency connection solution with low power consumption typical of passive twinax copper DACs. Manufactured to MSA-compliant mechanical and electrical specifications, the cable is compatible with major hardware platforms that accept SFP+ DACs. Its short 1 m length and twinax construction reduce latency and signal loss for rack-to-rack or intra-rack links while offering a cost-effective option compared with active optical modules for similar short-range interconnects.

Suitable for

• High-speed connections between switches and top-of-rack devices within the same rack or adjacent racks
• Server-to-switch or switch-to-switch links in data centres and enterprise networks
• Storage area network links using FCoE or Fibre Channel at 10 Gbps over short distances

Key specifications

• Cable type: Passive twinax copper direct attach cable (DAC)
• Data rate: Up to 10 Gbps
• Connector type: SFP+ to SFP+ (male/male)
• Length: 1 m
• Wire gauge: 30 AWG
• Colour: Black and silver
• Typical power: Passive (near-zero additional power consumption)

How to use

Insert each SFP+ connector firmly into the SFP+ ports of the devices to be linked, ensuring the retaining latch engages. Use the cable for short, direct electrical interconnects where both devices explicitly support passive SFP+ DACs. Verify link status and speed in device management interfaces after connection and follow vendor guidance when mixing third-party cables with proprietary hardware. Avoid sharp bends and excessive pulling force to maintain signal integrity and connector lifetime.

Recommendations

Use this 1 m passive SFP+ DAC for intra-rack or adjacent-rack connections where low latency and low power are priorities. Confirm hardware compatibility with device vendor documentation and, if available, test a sample before large deployments to ensure expected functionality within your specific platform and firmware version.
