Direct Attach Copper SFP+ Cable CBO Fujitsu S26361-F3873-E500-3 30 m

Direct Attach Copper SFP+ Cable CBO Fujitsu S26361-F3873-E500-3 30 m is a 30-metre passive DAC (Direct Attach Copper) cable engineered for short-range 10GbE connections between SFP+ ports in switches, servers and storage devices. The cable provides a direct wired link without separate optical transceivers, delivering low latency and predictable signal performance for data center interconnects, rack-to-rack links and server uplinks.

Advantages

This SFP+ DAC cable offers a cost-effective alternative to optical modules by integrating the copper twinax assembly and SFP+ connectors in a single unit. The design reduces power consumption and eliminates the need for separate transceivers, simplifying installation and maintenance. With a 30 m length it covers common rack-to-rack and short distance interconnects while preserving 10 Gigabit Ethernet throughput and minimal latency.

Suitable for

• Data center top-of-rack and rack-to-rack connections
• Server uplinks to aggregation switches
• Direct links between storage arrays and compute nodes
• Short-range 10GbE network segments within equipment rooms

Key specifications

• Cable type: passive Direct Attach Copper (twinax)
• Connector type: SFP+ duplex on both ends
• Rated data rate: 10 Gigabit Ethernet
• Length: 30 metres
• Typical latency: minimal/low for direct copper links
• Power consumption: lower than equivalent optical transceiver solutions
• Operating environment: designed for short-reach indoor data center use

How to use

Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on the network devices until the latch clicks into place. Ensure both devices support SFP+ passive DAC connectivity and that the ports are configured for 10GbE operation. Verify link status through device LEDs or management interfaces. To remove, depress the latch and pull the connector straight out to avoid bending the cable near the connector ends.

Recommendations

Route the cable within racks and cable trays to avoid sharp bends and mechanical stress; maintain the manufacturer’s minimum bend radius. Use this passive DAC for short-reach 10GbE links where cost, power efficiency and low latency are priorities. Do not use in outdoor or long-distance runs beyond its rated 30 m length.
