## Summary description

Direct Attach Copper (DAC) SFP28 cable from CBO, 0.5 m length, passive design for SFP28 ports. Provides a short-range, low-latency wired connection between networking devices supporting 25Gb/s SFP28 interfaces. Suitable for top-of-rack switches, servers and storage in data centers or telecom closets where cost-effective, power-efficient interconnects are required.

## Long description

The CBO SFP28 passive copper DAC cable 0.5 m is a short-range, direct-attach copper link designed for devices with SFP28 ports. Built for 25Gb/s SFP28 interfaces, this passive cable provides a compact, low-latency physical connection between switches, servers and storage units. Its 0.5 meter length is intended for close-proximity interconnects such as top-of-rack (ToR) configurations and rack-to-rack links within data center or telecom environments where power consumption and cost per port are important considerations.
Advantages
The passive copper design eliminates the need for external power or active electronics within the cable, reducing power draw and heat. With native support for 25Gb/s signaling over SFP28 ports, the cable offers deterministic latency and a simple plug-and-play installation without transceiver modules. The short, fixed-length form factor minimizes cabling clutter and simplifies cable management in dense rack layouts.
Suitable for
Top-of-rack switch connections to servers
Short rack-to-rack links in data center and telecom closets
Interconnects between storage arrays and host adapters within the same rack
Environments prioritizing low latency and low power per port
Key specifications
Interface type: SFP28 to SFP28 copper direct attach
Nominal data rate: 25 Gigabits per second
Length: 0.5 meter
Design: Passive copper (no active components in the cable)
Typical usage: Short-reach interconnects within racks or adjacent racks
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the networking devices until the latch engages. Ensure devices are powered off or follow hot-swap guidelines of your hardware vendor when connecting or disconnecting to avoid transient states. After physical installation, verify link status and speed through the device management interface. No additional configuration is required for basic connectivity beyond standard port enabling and speed/duplex settings if applicable.
Usage recommendations
Use the cable for direct short-range connections within the same rack or between adjacent racks. Avoid excessive bending near the connector and maintain recommended bend radii to preserve signal integrity. Confirm compatibility with your hardware vendor’s supported SFP28 passive DAC list if vendor lock or firmware restrictions apply.
