CBO DAC-kabel SFP28-DAC-1M 1 m passieve SFP28-Direct-Attach-koperkabel

BlueOptics CBO DAC Cable SFP28-DAC-1M is a 1 m passive direct-attach copper cable engineered for SFP28 ports. The cable provides a low-latency, compact physical link suitable for 25GbE or compatible SFP28 interfaces in switches, servers and storage equipment. Its fixed twin-ax copper construction eliminates the need for separate transceivers and offers a cost-effective short-reach interconnect for rack-to-rack and intra-rack connections in data center and enterprise network topologies.

Advantages

The passive SFP28 direct-attach design delivers low power consumption and minimal added latency compared with optical transceivers. At 1 m length the cable maintains signal integrity for short-reach 25GbE links while simplifying installation through a single integrated module on each end. Its form factor is compatible with SFP28 ports, enabling hot-plug connectivity and straightforward replacement or reconfiguration without additional cabling adapters.

Suitable for

• Short-reach 25GbE connections between switches and servers
• Intra-rack and adjacent-rack interconnects in data centers
• Direct server-to-storage links requiring low latency
• Environments where cost-effective, low-power cabling is preferred

Key specifications

• Connector type: SFP28 direct attach copper
• Cable type: passive twin-ax copper assembly
• Length: 1 meter
• Data rate compatibility: 25GbE and compatible SFP28 interfaces
• Form factor: SFP28 compliant plug-and-play modules on both ends
• Typical use: short-reach interconnects within racks and between adjacent racks

How to use

Install the cable by inserting each SFP28 module into the corresponding SFP28 port on your network devices until the latch clicks. Confirm link negotiation and speed settings on both devices; in most systems the connection will be recognized automatically as a 25GbE link. Avoid sharp bends and keep the cable clear of cable management strain points. For device changes, power state is typically not required for insertion or removal, but follow your equipment vendor’s guidance for hot-plug operations to prevent transient link issues.

Recommendations

Use this 1 m passive DAC cable for short, high-density interconnects where 25GbE performance and low power consumption are priorities. Verify SFP28 port compatibility and firmware support on both ends before deployment, and route cables to avoid excess bending or mechanical stress.
