Cabo de cobre SFP28 Direct Attach CBO SFP28-DAC-5M-CI-BL 5 m macho para macho 25 Gbit/s

CBO SFP28-DAC-5M-CI-BL is a direct-attach copper cable with SFP28 male connectors on both ends, designed to deliver 25 Gbit/s connectivity over a 5 m link. Intended for short-reach interconnects in data centers, the cable eliminates the need for optical transceivers and provides a fixed, low-latency electrical connection between servers, switches and storage devices. Its compact, passive copper construction helps reduce power consumption and simplifies rack cabling for top-of-rack and server-to-switch deployments.

Advantages

The SFP28 direct-attach copper cable offers a cost-effective alternative to optical modules for short-distance 25GbE links, providing predictable latency and stable throughput. Its plug-and-play SFP28 male ends ensure straightforward installation and hot-swap compatibility with compatible ports. The fixed 5 m length avoids signal degradation associated with longer copper runs and supports energy-efficient operation compared with active transceiver-based links.

Suitable for

• Top-of-rack switch to server connections
• Server-to-storage appliance interconnects within the same rack or adjacent racks
• Short-reach 25 Gigabit Ethernet uplinks in data center cabinets
• High-density patching where fixed copper links reduce cost and power

Key specifications

• Connector type: SFP28 male to SFP28 male
• Data rate: 25 Gbit/s (per cable link)
• Length: 5 meters
• Cable medium: Direct-attach copper (DAC)
• Latency: low, electrical direct-attach connection
• Compatibility: designed for SFP28 ports supporting 25GbE

How to use

Insert each SFP28 connector into compatible SFP28 ports on networking equipment until the latch engages. Ensure both devices support 25 Gbit/s electrical links and power is applied according to equipment guidelines. No transceivers or separate modules are required; once connected, configure interfaces on networking devices as needed to enable the 25GbE link. For best results, avoid tight bends and keep the cable routed within the rack to minimize physical stress.

Recommendations

Use this direct-attach cable for short, fixed interconnects within racks or between adjacent racks. Verify port compatibility and firmware support on networking equipment before deployment, and follow vendor guidance for supported passive DAC lengths to ensure reliable 25GbE operation.
