InfiniBand/fibre optic cable BlueOptics MC3309124-0A3-BL 3 m SFP+ Male/Male

The BlueOptics MC3309124-0A3-BL is a 3 m InfiniBand/fibre optic direct attach cable with SFP+ male-to-male connectors designed for short-distance, high-speed interconnects in racks and adjacent rack rows. It implements a 10GBase-CR compatible twinax copper construction with 30 AWG conductors and MSA-compliant SFP+ terminations, providing a low-latency, low-power physical link for Ethernet, FCoE, Fibre Channel and InfiniBand up to 10 Gbit/s over a 3 meter span. The cable is intended for use where vendors support passive SFP+ direct attach cables and offers a compact solution for linking switches, servers, storage systems and other SFP+-equipped devices.

Advantages

The cable combines a passive twinax copper design with SFP+ male connectors to deliver reliable 10 Gbit/s signal transmission without active circuitry in the cable itself, resulting in minimal power consumption and low latency. MSA-compliant terminations and quality components ensure broad interoperability with major networking platforms that accept compatible 10GBase-CR direct attach cables. The 3 m length is optimized for rack-to-rack and within-rack connections and supports common storage and networking protocols while keeping installation and maintenance requirements low.

Suitable for

• Short-distance links between switches, servers and storage appliances in racks
• 10GBase-CR Ethernet and FCoE connections up to 10 Gbit/s
• InfiniBand and Fibre Channel links where passive SFP+ direct attach cables are supported
• High-density cabling scenarios in data centers and server rooms

Key specifications

• Connector type: SFP+ male to SFP+ male
• Length: 3 meters
• Supported data rates: up to 10 Gbit/s
• Cable type: passive twinax copper (30 AWG)
• Standards: MSA-compliant SFP+ direct attach (10GBase-CR compatible)
• Typical applications: Ethernet, FCoE, Fibre Channel, InfiniBand (short-reach)
• Power consumption: passive design with negligible per-cable power draw

How to use

Insert each SFP+ connector into the SFP+ port of the devices to be linked, ensuring the latch engages and the connectors are fully seated. Use only in equipment that explicitly supports passive SFP+ direct attach twinax cables; consult device vendor documentation to confirm compatibility and any required firmware or port settings. Route the cable to avoid tight bends and mechanical strain, maintaining the manufacturer’s recommended bend radius, and secure the cable within the rack to prevent disconnection during maintenance or movement.

Recommendations

For best results, verify vendor compatibility before deployment, keep cable runs within the specified 3 m length, and avoid routing the cable near high-power electrical lines to minimize interference. Periodically inspect connectors for contamination and reseat connections if link issues occur. If active long-reach fiber is required, choose an appropriate optical transceiver and fiber solution instead of a passive twinax cable.
