## Summary description

Passive SFP28 DAC copper cable by CBO, model SFP28-DAC-0.5M, length 0.5 m. Designed for short-reach direct-attach connections between SFP28 ports in switches, servers and network appliances. Provides low-latency, energy-efficient 25GbE connectivity for rack-to-rack or within-rack links. Plug-and-play, no additional transceivers required.

## Long description

Passive SFP28 DAC copper cable CBO SFP28-DAC-0.5M 0.5 m is a direct-attach cable for 25GbE connections between SFP28 ports. The cable provides a fixed copper twinax connection for short-reach links inside racks or between adjacent racks. It is a plug-and-play solution that does not require separate transceivers, delivering low latency and reduced power consumption compared with optical transceivers for the same link distance.
Advantages
This passive SFP28 DAC cable offers a compact and reliable physical connection optimized for short-range 25 Gigabit Ethernet links. It minimizes insertion complexity by using integrated SFP28 connectors at both ends, ensuring compatibility with standard SFP28 ports. The passive design eliminates active electronics in the cable, contributing to lower power draw and predictable latency. The short 0.5 m length reduces signal attenuation and crosstalk for within-rack connections while simplifying cable management in dense server and switch environments.
Suitable for
 Short-reach 25GbE connections between switches and top-of-rack switches
 Direct links between servers and network appliances with SFP28 ports
 Within-rack or adjacent-rack interconnects in data centers and server rooms
 High-density equipment racks where compact cabling is required
Key specifications
 Interface: SFP28 to SFP28
 Data rate: 25 Gigabit Ethernet
 Cable type: Passive twinax copper
 Length: 0.5 m
 Form factor: Direct-attach cable with integrated SFP28 connectors
 Typical use: Short-reach, within-rack or adjacent-rack links
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the two devices to be connected, ensuring the latch engages. No additional transceivers, drivers, or configuration are required for basic physical connectivity; the devices will enumerate the link as a direct-attach connection. Verify link status and speed through the host device management interface or switch LED indicators after installation. For cable removal, press the release latch on the connector and pull straight out to avoid damaging the port.
Usage recommendations
Use the 0.5 m passive SFP28 DAC for short, high-throughput links inside racks or between adjacent racks. Ensure both endpoints support SFP28 direct-attach copper cables and that port firmware or vendor compatibility lists include passive DACs. Avoid sharp bends, excessive pulling force, and exposure to moisture or extreme temperatures to maintain mechanical and signal integrity.
