InfiniBand/kuitu-kaapeli SFP+ BlueOptics CAB-SFP-SFP-2M-BL 2 m uros/uros

The BlueOptics CAB-SFP-SFP-2M-BL is a 2-meter SFP+ direct attach cable designed for 10 Gigabit environments. With SFP+ male connectors on both ends and a 2 m length, it provides a short-reach connection option for switches, routers, servers and storage devices that accept SFP+ interfaces. The cable implements a twinax copper direct attach design suitable for cost-effective, low-latency links in racks or between adjacent racks and supports common 10G protocols including Ethernet, FCoE and Fibre Channel when used with compatible hardware.

Advantages

This SFP+ cable offers a compact, low-power connection with passive twinax copper construction that does not require additional transceivers or external power. The short 2 m length reduces signal attenuation and latency compared with longer active optic runs, while the SFP+ male-to-male form factor ensures straightforward insertion into SFP+ ports. The cable is built to MSA-compliant mechanical specifications and uses proven components for reliable long-term operation in data center environments.

Suitable for

• Short-reach 10 Gigabit links inside server racks and between adjacent racks
• Direct connections between switches, routers and storage arrays with SFP+ ports
• Environments requiring low latency and low power consumption

Key specifications

• Connector type: SFP+ male to SFP+ male
• Length: 2 meters
• Data rate support: up to 10 Gbit/s
• Cable type: twinax copper direct attach (passive)
• Typical use: Ethernet, FCoE, Fibre Channel and InfiniBand-compatible topologies at short distances
• Power consumption: passive (no added power for the cable itself)

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the network devices until the latch engages. Ensure the host devices officially support passive SFP+ twinax direct attach cables for 10GBase-CR operation. After physical installation, verify link status in the device management interface and confirm the negotiated speed is 10 Gbit/s. If required by the platform, check or update firmware and port settings to enable auto-negotiation or fixed speed operation according to the hardware vendor's guidance.

Recommendations

Use this 2 m SFP+ twinax cable for short copper connections inside racks or between adjacent racks where low latency and low power consumption are priorities. Avoid tight bends, excessive pulling force, and installation in high-electrical-noise environments. Confirm device compatibility with passive SFP+ DACs before deployment and test link behavior in a lab or single link before large-scale rollouts.
