SFP+ kabel BlueOptics LM-SFP-DAC-5M-BL 5 m samec/samec

The BlueOptics LM-SFP-DAC-5M-BL is a 5m SFP+ direct attach cable (DAC) with SFP+ male connectors on both ends designed for short-reach, high-speed 10G data links. This passive twinax copper cable follows MSA guidelines and implements 24 AWG conductors to deliver 10GBase-CR class performance over a 5 meter distance. It is intended for connecting switches, routers, servers and storage hardware in racks and between adjacent racks where a reliable, low-latency copper interconnect is required.

Advantages

The cable provides a cost-effective, low-power and low-latency connection for 10 Gbit/s networking applications without active transceiver electronics. Its MSA-compliant SFP+ connectors and twinax construction ensure wide compatibility with major networking platforms that accept passive DACs. With a compact form factor and fixed 5 m length, the cable simplifies rack cabling and reduces points of failure compared with separate transceiver-plus-fiber assemblies.

Suitable for

• Short-reach 10G links between rack-mounted switches
• Server to top-of-rack switch connections
• Interconnections between adjacent racks and patch panels
• Storage and SAN ports supporting 10GBase-CR, FCoE or InfiniBand

Key specifications

• Interface: SFP+ male to SFP+ male
• Length: 5 meters
• Cable type: Passive twinax copper (DAC)
• Conductor gauge: 24 AWG
• Supported link speed: up to 10 Gbit/s
• Standards: 10GBase-CR, compatible with FCoE and InfiniBand use cases
• Power consumption: passive (no additional power draw from cable electronics)

How to use

Insert each SFP+ connector into the corresponding SFP+ port on your devices until the connector latches. Verify that both devices support passive 10G DAC interconnects and that the port settings match the intended protocol (Ethernet/FCoE/InfiniBand). After installation, check link status and speed in the device management interface and ensure proper cable routing to avoid excessive bending or mechanical stress.

Recommendations

Route the cable within rack cable management pathways, avoid tight bends below the manufacturer’s minimum bend radius, and keep the cable away from high-heat sources. Use the 5 m length for short inter-rack or in-rack links; for longer runs, use active optical modules or fiber solutions. If compatibility with a specific vendor platform is critical, test the cable in your environment before large-scale deployment.
