## Summary description

CBO SFP28-DAC-2M is a 2‑meter passive SFP28 direct-attach copper cable designed for short‑reach 25GbE connections between switch ports, servers and network appliances. The assembled SFP28 modules provide a plug‑and‑play solution with low latency and reduced power compared to active optics, suitable for data center top‑of‑rack and aggregation links.

## Long description

CBO SFP28-DAC-2M is a 2-meter passive SFP28 direct-attach copper cable engineered for short-reach 25GbE connections. The assembly includes SFP28-compliant plug modules on both ends to enable direct, low-latency links between switch ports, servers and network appliances without the need for separate transceivers or fiber cabling. Designed for data centre top-of-rack and aggregation links, the passive DAC solution offers straightforward plug-and-play installation and reduced power consumption compared with active optical or active cable alternatives.
Advantages
The passive SFP28 DAC cable provides low latency and consistent electrical performance for short-distance 25 Gigabit Ethernet links. As a copper direct-attach solution it eliminates the need for separate fiber transceivers and fiber patching at short reach, simplifying port management and reducing hardware count. The assembled SFP28 modules are hot-pluggable and interoperable with standard SFP28 cages, offering immediate connectivity with minimal configuration. Passive design means lower power draw and lower total cost of ownership in environments where active optics are unnecessary.
Suitable for
 Top-of-rack connections between switches and servers in data centres
 Aggregation and leaf-spine short-reach links within racks
 Direct connections between network appliances, NICs and switch ports
 Environments where low latency and reduced power consumption are priorities
Key specifications
 Cable type: passive twinax copper direct-attach cable with SFP28 terminated modules
 Data rate: 25 Gigabit Ethernet (25GbE)
 Length: 2 meters
 Connector type: SFP28 form-factor on both ends, hot-pluggable
 Reach: short-reach electrical link optimized for intra-rack and adjacent-rack connections
 Power: passive design with minimal power consumption compared to active modules
How to use
Insert each SFP28 module end into the SFP28 cage of the corresponding switch, server or network appliance until the latch clicks into place. Ensure the connected ports are configured for 25GbE operation as required by your equipment. No additional cabling or transceivers are needed; the assembled cable provides a direct electrical connection. To remove, press the module latch and pull the module straight out. Follow your equipment vendor’s hot-plug guidance to avoid disruption to active links.
Usage recommendations
Use this passive SFP28 DAC for short intra-rack and adjacent-rack 25GbE links where fiber is not required. Verify compatibility with your switch or server vendor and confirm port speed settings before deployment. Avoid excessive bending or mechanical strain on the cable and keep connectors free of dust and contaminants to maintain signal integrity.
