## Summary description

CBO SFP28-DAC-2M is a 2 meter passive direct-attach copper (DAC) cable for SFP28 ports. Designed for short-reach connections between network switches, servers and storage, it supports 25Gbps SFP28 links with low latency and reduced power consumption compared to active optics. Plug-and-play form factor simplifies rack-level interconnects and helps lower hardware and operational costs.

## Long description

CBO SFP28-DAC-2M 2 m passive SFP28 direct-attach copper cable is a 2-metre direct-attach copper (DAC) cable engineered for SFP28 ports to connect network switches, servers and storage within short rack or row distances. The cable supports 25 Gbps SFP28 links, providing a low-latency, low-power alternative to active optical transceivers for short-reach interconnects. Its plug-and-play SFP28 form factor enables straightforward installation and immediate link establishment without additional configuration.
Advantages
The passive direct-attach construction reduces power consumption and removes the need for separate transceivers, which lowers both initial hardware expense and ongoing operational costs. The 2 m length is suitable for top-of-rack and adjacent-rack connections, offering reliable electrical performance for 25 Gbps links with minimal signal processing and low latency. The standardised SFP28 connectors ensure compatibility with equipment that supports SFP28 DAC modules, while the fixed cable assembly simplifies cabling management in dense environments.
Suitable for
 Top-of-rack switch to server connections inside the same rack
 Adjacent rack interconnects within data centre rows
 High-density switch fabrics requiring 25 Gbps short-reach links
 Server-to-storage links where low latency and low power are important
Key specifications
 Connector type: SFP28 direct-attach copper (fixed assembly)
 Length: 2 m
 Throughput: supports 25 Gbps per link
 Type: passive copper DAC (no active electronics in the cable)
 Latency: low-latency electrical interconnect suitable for short-reach links
 Usage environment: designed for rack and data centre short-reach connections
How to use
Install the CBO SFP28-DAC-2M by inserting each SFP28 connector into the corresponding SFP28 port on your switch, server or storage device until the latch engages. Ensure both ports support passive SFP28 DAC modules and that the devices are powered according to vendor guidelines. No additional configuration is required at the cable level; the link should negotiate at 25 Gbps if both endpoints support that speed. Route the cable to avoid sharp bends and maintain recommended bend radius for copper assemblies.
Usage recommendations
Use this passive 2 m SFP28 DAC for short-distance, high-density installations where reduced power consumption and minimal latency are priorities. Verify compatibility with the network equipment vendor's SFP28 DAC support list and maintain neat cable routing to preserve signal integrity and airflow in racks.
