## Summary description

Passive copper direct-attach (DAC) cable by CBO, 1 meter length, designed for SFP28 25Gb connections. This CBO SFP28-DAC-1M provides a fixed, low-latency link for short-distance interconnects between switches, servers or NICs supporting SFP28 ports. Ideal for rack-to-rack or within-rack connections where a reliable, power-efficient 25Gb link is required.

## Long description

The CBO SFP28 passive copper DAC cable 1m for 25Gb QSFP28/SFP28 connectivity is a fixed-length direct-attach copper cable engineered for short-range 25Gb links. Designed for SFP28 ports, this 1 meter passive DAC provides a low-latency, power-efficient physical connection between switches, servers and network interface cards. The cable supports 25 Gigabit Ethernet signaling and is suitable for dense rack environments where predictable performance and simple physical cabling are needed.
Advantages
This passive copper DAC offers predictable electrical performance with minimal signal processing, which reduces latency compared with active optical transceivers. The fixed 1 m length simplifies cable management in rack-to-rack or within-rack deployments and eliminates the need for separate transceivers and fiber patch cords. Low power consumption and a compact form factor make it suitable for high-density top-of-rack and middle-of-row installations.
Suitable for
Short-distance 25GbE connections between switches in the same rack
Server-to-switch links where SFP28 ports are available
High-density network aggregation in data center racks
Interconnects between network interface cards and top-of-rack switches
Key specifications
Interface type: SFP28 form factor compatible with SFP28 ports
Data rate: 25 Gigabit Ethernet
Cable type: Passive copper direct-attach cable (DAC)
Length: 1 meter
Latency: Low-latency direct electrical connection
Power: Passive design, no external power required
Typical use: Short-reach rack and within-rack interconnects
How to use
Insert each end of the DAC cable firmly into the corresponding SFP28 ports on the devices until the latch engages. Ensure both devices are powered down or follow hot‑plug guidelines provided by the device manufacturer if supported. After installation, verify link status on the connected equipment and confirm the negotiated 25Gb link speed. For removal, depress the latch and pull the connector straight out to avoid damaging the port.
Usage recommendations
Use this 1 m passive DAC for short, fixed-path connections inside racks or between adjacent racks. Avoid tight bends and excessive pulling; maintain the manufacturer’s minimum bend radius. Confirm compatibility with your switch or server vendor’s supported transceiver and DAC list to ensure link recognition and full performance.
