BlueOptics X6566B-5-R6-BL InfiniBand/fibre optic cable 5 m SFP+ Black

The BlueOptics X6566B-5-R6-BL InfiniBand/fibre optic cable 5 m SFP+ Black is a 5-metre SFP+ patch cable designed for high-speed short-range links in rack and adjacent-rack environments. It provides a direct attach solution for 10G-class connections and is intended for use with SFP+ ports on switches, routers, servers and storage equipment. The cable combines a compact SFP+ to SFP+ form factor with robust construction to support stable data transmission and low latency in data centre and enterprise networks.

Advantages

This SFP+ cable supports up to 10 Gbit/s data rates over a 5 m distance and is manufactured to align with industry MSA standards. Its twinax/direct-attach design gives low power consumption and minimal latency compared with active optical modules for equivalent short-range links. The cable uses quality components and a shielded 24 AWG twinax conductor to ensure reliable signal integrity, predictable performance and long service life for rack-to-rack connectivity.

Suitable for

• 10G Ethernet links between switches and servers within racks or across adjacent racks
• High-speed storage and SAN connections including Fibre Channel and FCoE on supported platforms
• InfiniBand and other 10G-compatible interconnects where SFP+ ports are used
• Short-distance data centre patching and direct-attach use in enterprise networks

Key specifications

• Connector type: SFP+ to SFP+
• Cable length: 5 metres
• Data rate: up to 10 Gbit/s
• Cable type: passive twinax / direct attach copper
• Conductor gauge: 24 AWG
• MSA-compliant form factor for SFP+ interfaces
• Typical applications: Ethernet, FCoE, Fibre Channel and InfiniBand at 10G

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the network devices until the latch clicks to secure the connection. Ensure both connected devices support passive 10G direct-attach twinax cables and that the firmware or software settings permit passive DAC operation. Route the cable carefully inside racks to avoid sharp bends and mechanical strain; maintain the minimum bend radius specified by the manufacturer of your hardware to preserve signal integrity. For initial deployment, verify link lights and run basic throughput tests to confirm the connection operates at the expected speed.

Usage recommendations

Use this cable for short-range 10G links inside and between adjacent racks where low latency, low power consumption and cost-efficiency are priorities. For longer distances or when optical isolation is required, choose active optical or fibre solutions instead. Periodically inspect connectors for dirt or damage and keep mating ports powered down or covered during maintenance to prevent contamination.
