CBO DAC SFP+ cable Fujitsu EBR800-TWX-1M 1 m direct-attach copper

The CBO DAC SFP+ cable Fujitsu EBR800-TWX-1M 1 m direct-attach copper is a factory-terminated twinax copper cable engineered for short-range 10 Gbps links between compatible SFP+ ports. With a 1 metre length, this direct-attach solution eliminates the need for separate optical transceivers, enabling low-latency, low-power wired connectivity for switches, servers and storage systems in racks and data centre topologies. The cable is intended for point-to-point connections where SFP+ form-factor ports are supported and provides a plug-and-play alternative to fiber optics for short-reach applications.

Advantages

This direct-attach copper cable offers predictable 10 Gbps performance with minimal signal conversion overhead, reduced power consumption compared with active optical solutions and a simplified physical layer by combining cable and connectors in a single assembly. The 1 m length reduces excess slack in dense rack environments, and compatibility with standard SFP+ ports allows straightforward deployment without additional transceivers. The twinax construction ensures low latency and consistent electrical characteristics appropriate for server-to-switch and switch-to-switch short links.

Suitable for

• 10 Gbps short-range links between SFP+ ports in network switches and routers
• Server-to-switch and storage-to-switch interconnects within the same rack or adjacent racks
• Data centre top-of-rack and middle-of-row cabling where 1 m reach is sufficient
• Environments prioritising reduced power and lower per-link cost compared with optical transceivers

Key specifications

• Data rate: 10 Gbps (SFP+ compatible)
• Connector type: SFP+ direct-attach copper ends
• Length: 1 metre
• Media: Twinax copper cable (direct-attach)
• Latency: low electrical latency suitable for short-reach links
• Power: passive low-power design (no separate transceivers required)

How to use

Install the cable by inserting each SFP+ end into the corresponding SFP+ port on the devices to be connected, ensuring the latch engages for a secure connection. Confirm that both devices support passive SFP+ direct-attach copper connections and that firmware or port settings are configured for 10 Gbps operation if required. Avoid tight bends and mechanical strain on the cable; route the cable within the rack to prevent interference with airflow and adjacent equipment. For troubleshooting, verify link LEDs on both devices and swap ports or cables to isolate faults.

Recommendations

Use this 1 m DAC cable for intra-rack or adjacent-rack 10 Gbps links where the SFP+ ports are known to accept direct-attach copper assemblies. Maintain recommended bend radius and avoid placing heavy objects on the cable to preserve signal integrity and connector durability.
