## Summary description

Passive copper CBO DAC cable SFP28-DAC-0.5M, 0.5 m length, designed for direct connections between SFP28 ports. Provides a short, low-latency, energy-efficient link for 25GbE or compatible SFP28 interfaces in switches, servers, and storage equipment. Ideal for rack-to-rack or intra-rack connections where a fixed short-range cable is required.

## Long description

The CBO DAC cable SFP28-DAC-0.5M is a 0.5 m passive copper direct attach cable designed for short-range connections between SFP28 interfaces. It provides a fixed, low-latency link suitable for 25GbE or compatible SFP28 ports in switches, servers and storage systems. The compact, plug-and-play form factor eliminates the need for separate transceivers and is intended for rack-to-rack or intra-rack connectivity where a durable, short copper connection is preferred.
Advantages
This passive copper SFP28 to SFP28 cable offers minimal power consumption and low latency compared with active optics or optical transceivers. Its short fixed length simplifies cable management in dense rack environments and reduces signal conversion points. The direct-attach design provides reliable electrical performance for high-speed 25GbE links while lowering overall deployment cost for short-distance connections within a data center.
Suitable for
Short-range 25GbE links between switches and top-of-rack equipment
Direct server-to-switch or server-to-storage interconnects within the same rack
Environments that require low-latency, energy-efficient copper connections
Data center cabling where fixed-length, durable interconnects are preferred
Key specifications
Connector type: SFP28 to SFP28 compatible
Cable type: Passive copper direct attach
Length: 0.5 m
Supported data rate: 25 Gigabit Ethernet (25GbE) or compatible SFP28 rates
Form factor: Twinax direct attach cable with integrated connectors
Typical use case: Short-distance, rack-level interconnects
How to use
Install the cable by aligning and inserting each SFP28 connector into the corresponding SFP28 port until the latch engages. Ensure both devices support passive DAC operation and that ports are configured for the intended 25GbE link speed. No external power or transceivers are required; the link becomes operational once both ends are properly seated and the network interfaces are configured. For equipment hot-plugging, follow the host device manufacturer’s guidelines to avoid link disruption.
Usage recommendations
Use this 0.5 m passive DAC for short, direct connections within racks or adjacent racks. Avoid routing the cable near high-heat sources or sharp bends; maintain bend radius consistent with the cable construction to preserve signal integrity. Verify device compatibility with SFP28 passive copper cables and confirm link speed and duplex settings in the network equipment to ensure stable operation.
