InfiniBand/fibre optic cable BlueOptics 740-032276-BL 3 m SFP+ Male/Male

The BlueOptics 740-032276-BL is a 3 m InfiniBand/fibre optic cable with SFP+ male-to-male connectors designed for short-range, high-speed connections in rack and adjacent-rack environments. It is built to support 10G data rates and common protocols such as Ethernet, FCoE, Fibre Channel and InfiniBand when used on compatible hardware platforms that accept SFP+ direct attach connections. The cable is suitable for passive direct-attach twinax applications where low latency, low power consumption and compact cabling are required.

Advantages

This cable provides a straightforward, low-latency connection for 10G links with SFP+ interfaces and is compatible with major hardware platforms that support the original specification. The 3 m length is appropriate for in-rack and adjacent-rack links, delivering reliable electrical signal transmission over short distances. Manufactured to MSA-compliant standards and assembled from industry-grade components, the cable offers consistent performance and long operational life for demanding data centre and networking setups.

Suitable for

• Connecting switches and routers within the same rack or adjacent racks
• Server-to-switch and server-to-storage short-range links
• 10G Ethernet, FCoE, Fibre Channel and InfiniBand connections over SFP+ ports
• Data centre top-of-rack and aggregation cabling where passive DAC is supported

Key specifications

• Connector type: SFP+ male to SFP+ male
• Length: 3 meters
• Supported data rate: up to 10 Gbit/s
• Type: passive direct attach twinax (DAC) for short-distance electrical transmission
• Wire gauge: 30 AWG
• Standards: MSA-compliant SFP+ form factor and electrical characteristics

How to use

Ensure both network devices support passive SFP+ twinax direct attach cables before installation. Power down or follow hot‑swap guidance from the device manufacturer if required, then insert each SFP+ connector into the corresponding SFP+ port until it latches. Verify the link LEDs or device interface for an active 10G connection and confirm protocol compatibility (Ethernet, FCoE, Fibre Channel or InfiniBand) within your equipment. For removal, release the latch mechanism and withdraw the connector straight out to avoid port damage.

Recommendations

Use this cable for short-range, high-bandwidth links inside racks or between adjacent racks. Avoid routing near strong electromagnetic interference sources and do not exceed the recommended distance for passive DAC operation. Store and handle the cable to prevent sharp bends and kinks to maintain optimal signal integrity and long service life.
