InfiniBand/optický kabel BlueOptics 450-16140-BL 3 m SFP+ samec/samec

The BlueOptics 450-16140-BL is a 3 m InfiniBand/fibre optic assembly with SFP+ male-to-male connectors designed for short-reach, high-speed links in racks and adjacent rack connections. Built to support 10G data rates, this cable implements a Direct Attach Copper (DAC) twinax topology with 30 AWG conductors and SFP+ terminations for direct connection between SFP+ ports on switches, routers, storage systems and hosts. The design follows MSA guidelines for form factor and electrical compatibility to ensure interoperability with equipment that accepts SFP+ passive DACs.

Advantages

The cable provides a low-latency, low-power and cost-effective physical link for short-distance 10G networks. Passive twinax construction reduces complexity by avoiding active electronics in the cable, yielding low failure rates and minimal power consumption. Components conform to common quality standards and the assembly is tested for interoperability with major hardware platforms, delivering predictable performance for Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 10 Gbit/s over the specified 3 m length.

Suitable for

• Interconnecting SFP+ ports within a rack or between adjacent racks
• 10G Ethernet, FCoE, Fibre Channel and InfiniBand short-reach links
• Switch-to-switch, switch-to-server, and switch-to-storage connections

Key specifications

• Length: 3 meters
• Connector type: SFP+ male to SFP+ male
• Transmission rate: up to 10 Gbit/s
• Cable type: passive Twinax / Direct Attach Copper
• Conductor gauge: 30 AWG
• Compliance: MSA-compatible SFP+ form factor and electrical interface

How to use

Identify compatible SFP+ ports on the devices to be linked and power down or follow hot-plug guidance from the equipment vendor if supported. Align the SFP+ plug with the port and insert the connector fully until it latches. Ensure link negotiation and speed settings on both ends are configured for 10G operation where required. If diagnostic LEDs or management interfaces are available, verify that the link is active and that no errors are reported. When removing the cable, release the latch and withdraw the connector straight out to avoid damaging the port.

Recommendations

Use this 3 m passive SFP+ DAC for short intra-rack or adjacent-rack connections where 10G performance is required and where the host hardware supports passive twinax DACs. Avoid routing the cable near strong electromagnetic interference sources and ensure bend radius limits are observed to maintain signal integrity. For longer distances, consider active optical cables or fibre solutions.
