InfiniBand/fibre optic cable BlueOptics 470-11430-BL 3 m SFP+ Male/Male

The BlueOptics 470-11430-BL is a 3 m InfiniBand/fibre optic cable with SFP+ connectors on both ends, intended for high-speed links in racks and adjacent rack rows. The cable implements a passive Direct Attach Cable (DAC) twinax copper design compatible with SFP+ ports and is suited for short-distance electrical signal transmission at 10 Gbit/s. It is designed for integration with switches, routers, storage systems and other hardware that support SFP+ passive DAC connections.

Advantages

The cable supports 10GBase-CR electrical links over a 3 m distance and is MSA-compliant, enabling straightforward interoperability with equipment that accepts SFP+ DAC modules. A passive twinax construction results in low power consumption and low latency compared with active transceiver solutions. Components from established connector and cable manufacturers are used to ensure stable signal integrity and long operational life under typical data center use.

Suitable for

• Short-reach 10 Gbit/s connections between servers and switches in racks
• Inter-rack links across adjacent rack rows in data centers
• Storage system and switch-to-switch connectivity supporting SFP+ DAC
• FCoE, Ethernet and InfiniBand applications up to 10 Gbit/s on short distances

Key specifications

• Length: 3 metres
• Connector type: SFP+ male to SFP+ male
• Transfer rate: up to 10 Gbit/s
• Cable type: passive twinax copper (Direct Attach Cable)
• Wire gauge: 30 AWG
• Standards: MSA-compliant for SFP+ DAC (10GBase-CR)

How to use

Install the BlueOptics 3 m SFP+ male-to-male DAC by inserting each SFP+ connector into the corresponding SFP+ port on the devices to be linked. Ensure both devices officially support passive SFP+ DAC connections and that ports are powered off or follow hot-plug guidelines from the hardware vendor when inserting or removing the cable. Verify link status via device management interfaces after connection to confirm proper negotiation at 10 Gbit/s.

Recommendations

Use this DAC for short-distance links inside racks or between adjacent racks; avoid routing the cable near high-EMI sources or sharp bends that could stress the twinax assembly. For reliable operation, confirm interoperability with your switch or server model and follow vendor guidance for passive SFP+ DACs.
