InfiniBand/fibre optic cable BlueOptics 46K6183-L36836B-BL 3 m SFP+ Male/Male

The BlueOptics 46K6183-L36836B-BL is a 3 m InfiniBand / fibre optic direct attach cable with SFP+ male-to-male connectors designed for short-range, high-speed connectivity in rack and adjacent-rack environments. It implements a passive 10GBase-CR twinax copper design (30 AWG) that is MSA compliant and compatible with major networking platforms that support SFP+ Direct Attach Cables. The cable supports Ethernet, FCoE, Fibre Channel and InfiniBand applications at up to 10 Gbit/s over a 3 m distance and is intended for linking switches, routers, storage systems and other SFP+ ports within data center racks.

Advantages

The cable provides a cost-effective direct attach solution for short-distance 10 Gbit/s links, combining low power consumption and low latency due to its passive twinax design. Manufacturing follows MSA standards and uses high-quality components to ensure stable signal integrity and long operational lifetime. Its SFP+ male-to-male connectors enable plug-and-play installation in compliant hardware, reducing complexity and maintenance needs compared with active or optical transceiver-based connections.

Suitable for

• 10 Gbit/s uplinks and server-to-switch connections within the same rack or adjacent racks
• High-performance Ethernet, FCoE and Fibre Channel short-range links
• Interconnects between storage arrays and switches with SFP+ ports
• Environments that require low-power, low-latency direct attach cabling

Key specifications

• Length: 3 meters
• Connector type: SFP+ male to SFP+ male
• Data rate: up to 10 Gbit/s
• Cable type: passive twinax copper (30 AWG)
• Compliance: MSA compliant
• Supported protocols: Ethernet, FCoE, Fibre Channel, InfiniBand

How to use

Ensure both devices support passive SFP+ Direct Attach Cables, then insert the SFP+ connectors into the SFP+ ports on each device until they latch. Route the 3 m twinax cable to avoid sharp bends and excessive stress on the connectors; maintain the minimum bend radius recommended for twinax cables. No external power or configuration is required for the cable itself, but verify link settings on connected devices if needed for protocol negotiation or link speed enforcement.

Recommendations

Use this 3 m passive SFP+ DAC for short-distance, high-throughput links inside racks and between adjacent racks. For longer runs or cross-room connections, consider active DACs or optical transceivers with fibre optic cabling. Verify device compatibility with passive SFP+ DACs and test new links after installation to confirm expected throughput and stability.
