InfiniBand/fibre optic cable BlueOptics 74752-1158-BL 2 m SFP+ Male/Male

The BlueOptics 74752-1158-BL is a 2 m InfiniBand/fibre optic cable with SFP+ male-to-male connectors designed for short-range high-speed links in racks and adjacent rack rows. As a passive direct attach cable (DAC) compatible with Molex 74752-1158 and compliant with SFP+ and MSA guidelines, it supports 10G data transmission for Ethernet, FCoE, Fibre Channel and InfiniBand applications where a reliable, low-latency copper twinax connection is required.

Advantages

This 2 m SFP+ cable provides a cost-effective, low-power solution for connecting switches, routers, storage arrays and server interfaces over short distances. Passive twinax construction yields low latency and minimal power consumption while meeting the physical and electrical requirements of SFP+ ports. BlueOptics units are tested for compatibility with major hardware platforms and are manufactured from high-quality components to ensure long operational life and stable throughput up to 10 Gbit/s on the specified length.

Suitable for

• Short-range rack-to-rack connections in data centers
• Interconnects between switches, routers and storage systems
• 10G Ethernet, FCoE, Fibre Channel and InfiniBand links up to 2 m
• Server uplinks and switch stacking where SFP+ ports are present

Key specifications

• Length: 2 m
• Connector type: SFP+ male to SFP+ male
• Transmission rate: up to 10 Gbit/s
• Cable type: passive twinax copper (direct attach)
• Wire gauge: 30 AWG
• Standards: SFP+ / MSA compliant
• Typical power consumption: passive (approx. 0.1 W per link when considered at system level)

How to use

Insert one SFP+ connector into each SFP+ port on the devices you intend to link, ensuring the latch engages and the connectors are fully seated. Use the 2 m length for connections inside a rack or between adjacent racks; avoid sharp bends and keep the cable clear of pinch points. Passive DAC operation requires that both connected devices support passive twinax SFP+ cables. Verify port settings and link speed on connected hardware and consult device documentation if link negotiation does not occur automatically.

Recommendations

For best results, route the cable to minimize mechanical stress, allow sufficient airflow around network equipment, and test links after installation. Use compatible SFP+ ports and verify vendor support for passive DACs in your hardware to ensure reliable 10G operation over the 2 m distance.
