## Summary description

CBO SFP28-DAC-1M is a 1‑metre passive SFP28 direct-attach copper cable designed for 25 Gigabit Ethernet connections. It provides a fixed, low-latency link between SFP28 ports on switches, servers or NICs without the need for transceivers. Ideal for short-reach rack-to-rack or within-rack interconnects, it offers simple installation and reduced power consumption compared with optical modules.

## Long description

CBO SFP28-DAC-1M is a 1 metre passive SFP28 direct-attach copper cable engineered for 25 Gigabit Ethernet links. The cable connects SFP28 ports on switches, servers or network interface cards to provide a fixed, low-latency physical connection without separate optical transceivers. Its compact, single‑cable form factor simplifies short-reach rack-to-rack or within-rack interconnects and reduces power consumption compared with active optical solutions.
Advantages
This passive SFP28 DAC cable delivers low latency and predictable performance for short-distance 25GbE links while eliminating the need for separate transceiver modules. The direct-attach copper design offers plug-and-play installation, lower power draw, and a reduced total cost of ownership for high-density deployments. A 1 m length provides a tidy cable path for adjacent equipment and minimizes signal attenuation typical of longer copper runs.
Suitable for
Short-reach connections between top-of-rack switches and servers
Within-rack uplinks and aggregation ports
High-density switch-to-switch interconnects in data centre racks
Server NIC to switch links in compute clusters
Key specifications
Interface: SFP28 to SFP28
Data rate: 25 Gigabit Ethernet
Construction: Passive copper direct-attach cable
Length: 1 metre
Form factor: Twinax direct-attach with SFP28 connectors
Typical use distance: short-reach (within rack or adjacent racks)
How to use
Insert one SFP28 connector into the SFP28 port of the first device and the other connector into the SFP28 port of the second device until each latch clicks into place. Ensure both devices are powered and that their ports support passive DAC connections at 25GbE. No additional modules, fibre patching, or configuration is typically required beyond verifying link speed and port settings in the switch or server management interface.
Usage recommendations
Use the cable for short, direct connections inside racks or between adjacent racks. Avoid tight bends and excessive force on the connectors; maintain a minimum bend radius consistent with twinax cabling and keep the cable away from sources of electromagnetic interference. Verify compatibility with device firmware and port auto-negotiation settings before deployment.
