SFP+ Direct-Attach Cable CBO J9284B-BL 5 m Male-to-Male 10 Gbit/s

BlueOptics SFP+ Direct-Attach Cable CBO J9284B-BL is a 5 m copper twinax assembly with male-to-male SFP+ connectors that supports 10 Gbit/s data rates. It is engineered for short-range interconnects in data centre and enterprise network environments, providing a fixed low-latency link between servers, switches and storage devices. The compact, factory-terminated cable eliminates the need for separate transceivers, helping to simplify rack-to-rack and within-rack connections while conserving SFP+ ports and reducing power and cost compared with optical modules.

Advantages

The cable offers stable 10 Gbit/s performance with predictable latency and minimal signal loss across its 5 m length. Its male-to-male SFP+ terminations provide hot-pluggable connectivity compatible with standard SFP+ ports. Being a copper direct-attach solution, it reduces complexity by removing separate transceiver modules and their power draw. The fixed assembly is factory-tested to ensure consistent electrical characteristics and reliable operation in short-reach topologies.

Suitable for

• Short-range server-to-switch and switch-to-switch links within racks or between adjacent racks
• Top-of-rack (ToR) and middle-of-row connections in data centres
• Storage area network connections with SFP+ interfaces
• Test lab environments and temporary high-speed links

Key specifications

• Data rate: 10 Gbit/s
• Cable type: Copper twinax direct-attach
• Connector type: SFP+ male-to-male
• Length: 5 meters
• Use case: Short-range interconnects (within-rack, rack-to-rack)
• Latency: Low, fixed-path copper link

How to use

Insert each SFP+ connector into the corresponding SFP+ port on your switch, server or storage device until the latch engages. Ensure both devices are powered and configured to support a 10 Gbit/s link; link negotiation is handled by the devices and the cable provides the physical layer. For best results, avoid sharp bends and maintain the recommended bend radius for twinax copper assemblies. When removing the cable, release the connector latches before pulling to prevent port damage.

Usage recommendations

Use this direct-attach cable for short, permanent or semi-permanent 10 Gbit/s connections where power efficiency and low latency are priorities. Verify compatibility with your hardware vendor’s SFP+ port policies and firmware, and keep the cable free from excessive mechanical strain and electromagnetic interference sources to preserve signal integrity.
