InfiniBand/fibre optic cable BlueOptics X1983-05-R6-BL 0.5 m SFP+ Male/Male

The BlueOptics X1983-05-R6-BL is a 0.5 m high-speed cable with SFP+ male-to-male connectors designed for short-range InfiniBand and fibre optic environments. This direct attach solution implements a 10GBase-CR twinax copper topology suitable for linking equipment in racks or between adjacent racks where SFP+ ports are available. Intended for professional network and storage hardware, the cable supports common 10 Gbps protocols including Ethernet, FCoE and InfiniBand when used within its 0.5 m range.

Advantages

The cable provides a compact, passive direct-attach connection that eliminates the need for separate transceivers while maintaining low latency and low power consumption. Constructed to MSA-compliant form factors and using high-quality components, it offers reliable signal integrity for short-distance links and compatibility with major networking platforms that accept SFP+ to SFP+ direct attach twinax solutions. Its short length reduces clutter in rack installations and simplifies cabling for high-density setups.

Suitable for

• Connecting SFP+ ports on switches and routers within the same rack or adjacent racks
• Direct links between storage systems and servers supporting 10GBase-CR
• Short-distance InfiniBand or fibre optic interconnects requiring SFP+ form factor

Key specifications

• Connector type: SFP+ male to SFP+ male
• Cable type: passive twinax copper (10GBase-CR compatible)
• Length: 0.5 meter
• Data rate: up to 10 Gbps over specified distance
• Wire gauge: 30 AWG
• Form factor: MSA-compliant SFP+ direct attach

How to use

Verify that both endpoints support passive SFP+ direct attach twinax cables and the intended protocols (Ethernet, FCoE or InfiniBand) at 10 Gbps. With equipment powered down or following the vendor’s hot-plug guidelines, insert each SFP+ plug into the corresponding SFP+ port until it latches. Confirm link status and negotiated speed in the device management interface. For removal, release the connector latch and withdraw the cable carefully to avoid stress on the ports.

Recommendations

Use this 0.5 m passive SFP+ cable for short, high-density rack connections to minimize cable clutter and latency. Avoid bending the cable sharply and keep within the specified length for guaranteed 10 Gbps performance; consult your equipment vendor for confirmed compatibility with passive direct-attach twinax cables.
