BlueOptics 740-030077-BL -InfiniBand-/kuituoptinen kaapeli 3 m SFP+ uros/uros

The BlueOptics 740-030077-BL is a 3 m InfiniBand/fibre optic cable with SFP+ connectors on both ends. It provides a direct attach connection for 10G-class links and is designed for short-distance, high-speed data transmission between devices in racks or across adjacent racks. The cable supports electrical 10GBase-CR signaling and is suitable for applications such as Ethernet, FCoE and InfiniBand where SFP+ interfaces are used.

Advantages

This 3 m SFP+ Male/Male cable offers a passive direct-attach design that requires no external power or active transceivers, resulting in low power consumption and minimal latency. Manufactured to match MSA specifications, it uses quality components to provide reliable connectivity and long service life for rack-to-rack or intra-rack links. The cable is compatible with equipment that supports 10GBase-CR SFP+ direct attach connections and is a cost-effective alternative to active optical transceivers for short runs.

Suitable for

• 10 Gbps Ethernet links between switches and servers
• Fibre Channel over Ethernet (FCoE) connections in storage networks
• InfiniBand and high-speed interconnects in data center racks
• Short-distance rack-to-rack or intra-rack device connections

Key specifications

• Cable length: 3 m
• Connector type: SFP+ male to SFP+ male
• Supported data rate: up to 10 Gbps
• Transmission type: passive direct attach (twinax copper / electrical 10GBase-CR compatible)
• Physical construction: twinax copper with 30 AWG conductors

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on your network devices until the latch engages. Ensure both devices support passive SFP+ direct-attach cables and the 10GBase-CR protocol. Check device port configuration and firmware compatibility if link negotiation does not complete. Route the cable to avoid sharp bends and maintain the recommended bend radius to preserve signal integrity and mechanical reliability.

Recommendations

Use this 3 m SFP+ direct attach cable for short-range, high-throughput connections inside racks or between adjacent racks. Verify compatibility with the host hardware and firmware before deployment, avoid excessive bending or strain, and keep connections clean and dust-free to ensure stable operation.
