## Summary description

Passive copper SFP28 DAC cable CBO SFP28-DAC-1M, 1 meter length, designed for direct-attach connections between SFP28 ports supporting 25GbE. Low-latency, low-power interconnect for short-distance links in data centers, top-of-rack switches and server pairs. Simple plug-and-play solution for reliable, cost-effective short-range connectivity.

## Long description

The BlueOptics Passive Copper SFP28 DAC Cable CBO SFP28-DAC-1M is a 1 metre direct-attach cable engineered for 25GbE connections between SFP28 ports. Designed for short-range interconnects in data centres, top-of-rack switches and server pairs, this passive DAC provides a low-latency, low-power alternative to active optical modules. The cable is supplied as a single assembly with SFP28 connectors at both ends for simple plug-and-play installation with compatible 25 Gigabit Ethernet equipment.
Advantages
This passive copper SFP28 DAC offers deterministic latency and minimal signal processing, which helps reduce power consumption compared with active transceivers. Its fixed 1 m length simplifies cable management in dense rack environments and eliminates the need for separate transceiver modules and fibre patch cords. As a direct-attach solution, it provides reliable electrical performance for short-distance 25GbE links and is suitable for high-density port deployments.
Suitable for
Short-range 25GbE links between switches and servers
Top-of-rack (ToR) connections in data centre racks
Server-to-server interconnects within the same rack or adjacent racks
High-density switch fabrics where low latency and reduced power draw are required
Key specifications
Connector type: SFP28 on both ends
Cable type: Passive copper direct-attach
Supported data rate: 25 Gigabit Ethernet
Length: 1 metre
Typical use: Short-range, intra-rack connectivity
Latency: Low, passive operation (no active signal conditioning)
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the network devices until the latch engages. Ensure both ends are fully seated and that the connected devices are powered and configured to use 25GbE links. No additional drivers or configuration are needed for the physical layer beyond standard network interface and switch setup. For best results, route the cable to avoid tight bends and excessive stress on the connector housings.
Usage recommendations
Use this 1 m passive DAC for intra-rack connections and short-distance links where a low-power, low-latency electrical connection is sufficient. Verify compatibility with the SFP28 ports on your switches and servers and avoid exposing the cable to temperatures or mechanical stresses outside the equipment manufacturer’s specified ranges.
