SFP+ cable CBO 2127933-1-BL 0.5 m Male-to-Male 10 Gbit/s

BlueOptics SFP+ cable CBO 2127933-1-BL 0.5 m Male-to-Male is a 10 Gbit/s copper direct-attach cable designed for short-reach high-speed interconnects. The 0.5 metre fixed-length cable integrates SFP+ style male connectors on both ends to provide a low-latency, low-power physical link between compatible switches, servers, storage arrays and network interface cards. Its compact, factory-terminated design enables plug-and-play installation in dense rack and data centre environments where space and signal integrity are important.

Advantages

This SFP+ direct-attach cable delivers reliable 10 Gbit/s connectivity with minimal signal loss and reduced latency compared with optical transceivers at short distances. The integrated male-to-male SFP+ connectors remove the need for separate transceiver modules, simplifying inventory and lowering deployment time. The short, fixed-length copper assembly offers predictable electrical performance and lower power consumption compared with active optical alternatives, making it suitable for cost- and energy-sensitive network topologies.

Suitable for

• Short-reach connections between top-of-rack switches
• Server-to-switch links in data centres and server rooms
• Direct links between network interface cards and storage devices
• High-density rack environments requiring compact cabling

Key specifications

• Data rate: 10 Gbit/s
• Cable type: Copper direct-attach (DAC)
• Connector type: SFP+ male-to-male
• Length: 0.5 m
• Latency: low, suitable for latency-sensitive applications
• Power: passive copper design with low power consumption
• Compatibility: designed for standard SFP+ ports on switches, servers and NICs

How to use

Confirm that both network devices have SFP+ ports that support passive copper direct-attach cables. With devices powered down or following hot-plug guidance from the equipment manufacturer, align each SFP+ male connector with the corresponding SFP+ cage and insert until it seats securely. After physical connection, verify link status and negotiate 10 Gbit/s on the devices' network interfaces. For removal, follow the equipment vendor instructions to avoid damaging the connector or cage.

Usage recommendations

Use this 0.5 m SFP+ DAC in short-distance scenarios within racks or adjacent racks. Avoid sharp bends and excessive tension on the cable; maintain a bend radius recommended for high-speed copper assemblies. Check device compatibility lists for SFP+ passive cable support and ensure firmware or driver settings allow auto-negotiation at 10 Gbit/s.
