DAC cable CBO SRX-SFP-10GE-DAC-1M 1 m SFP+ 10 Gbit/s

Direct Attach Copper (DAC) cable CBO SRX-SFP-10GE-DAC-1M is a 1 meter passive SFP+ twinax cable engineered for short-reach 10 Gbit/s links. It connects SFP+ ports on switches, routers and servers to provide low-latency, energy-efficient 10GbE connectivity within racks and top-of-rack data center deployments. The cable is purpose-built for stable, high-throughput connections where fiber optics are unnecessary or cost-prohibitive.

Advantages

This 1 m SFP+ DAC cable offers low insertion loss and minimal latency thanks to its passive twinax construction, making it suitable for direct server-to-switch or switch-to-switch links. The fixed length and integrated SFP+ plugs simplify installation and reduce the need for transceivers, lowering both capital and operational costs. Its robust connector design supports reliable mating cycles and consistent electrical performance in dense rack environments.

Suitable for

• Connecting servers to top-of-rack or leaf switches at 10 Gbit/s
• Short-range switch-to-switch links inside racks or between adjacent racks
• Low-latency database, virtualization and storage network segments
• Environments where cost-effective, power-efficient 10GbE cabling is required

Key specifications

• Interface: SFP+ to SFP+
• Nominal length: 1 metre
• Data rate: 10 Gbit/s
• Cable type: Passive twinax (Direct Attach Copper)
• Typical application: Short-range intra-rack and adjacent-rack connections
• Latency: Minimal, suitable for low-latency applications
• Power consumption: Passive solution with no additional power draw for transceivers

How to use

Insert each integrated SFP+ connector into the corresponding SFP+ port on the network devices until the latch engages. Use the 1 m length to route the cable cleanly within the rack, avoiding sharp bends and contact with sources of excessive heat. No additional configuration is required at the physical layer; devices may need standard network configuration for interfaces to become operational. For best signal integrity, ensure ports are SFP+ compatible and that firmware does not restrict passive DAC usage.

Usage recommendations

Install and remove the cable by handling the connector housings rather than pulling the cable itself. Keep the length suitable for your rack layout to prevent strain on ports. Validate compatibility with your equipment vendor’s SFP+ port policies when deploying in mixed-vendor environments.
