SFP+ Cable CBO CB-DASFP-0.5M-BL 0.5m Male-to-Male 10 Gbit/s

Direct-attach SFP+ cable CB-DASFP-0.5M-BL by BlueOptics is a 0.5 metre male-to-male copper twinax cable that supports up to 10 Gbit/s data rates. It is intended for short-range connections between network devices with SFP+ ports, offering a compact, low-latency alternative to optical transceivers. The cable is suitable for use in data centre topologies, server racks and short interconnects where high throughput and reduced power consumption are required.

Advantages

The cable delivers a reliable electrical 10 Gbit/s link with minimal latency and low power requirements compared with optical modules. Its short 0.5 m length keeps signal integrity high while minimising cable clutter in dense rack environments. Male-to-male SFP+ terminations ensure straightforward hot-pluggable insertion into compatible SFP+ ports without additional transceivers, and the construction provides robust mechanical connection for repeated use.

Suitable for

• Short-range server-to-switch connections inside racks
• Top-of-rack and end-of-row network interconnects
• Direct links between NICs and storage controllers with SFP+ ports
• Low-latency, high-density data centre patching

Key specifications

• Interface: SFP+ male-to-male twinax
• Length: 0.5 metre
• Maximum data rate: 10 Gbit/s
• Signal medium: copper twinax
• Typical application range: short-reach, within rack

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the devices to be linked, ensuring the latch mechanism engages. Use the 0.5 m length for direct, short-distance connections inside racks or between adjacent equipment shelves. No additional transceivers or fibre cabling are required; devices should recognise the direct-attach cable as an SFP+ link if they support passive copper twinax cables. Handle connectors by the housing and avoid excessive bending of the cable near the terminations to maintain signal integrity.

Recommendations

Verify device compatibility with passive SFP+ copper cables and confirm supported data rates and any vendor restrictions before deployment. For optimal performance, route the cable to avoid tight bends and electromagnetic interference from power supplies or high-current cables.
