## Summary description

3-meter passive copper DAC (direct-attach cable) CBO SFP28-DAC-3M designed for SFP28 ports supporting 25GbE. The twinax cable integrates SFP28 connectors on both ends for short-reach server-to-switch or switch-to-switch links, offering low-latency, low-power connectivity without transceivers. Suitable for data center rack interconnects and high-speed uplinks.

## Long description

The SFP28 Passive Copper DAC Cable CBO SFP28-DAC-3M is a 3-meter direct-attach twinax cable with SFP28 connectors on both ends, designed for equipment with SFP28 ports that support 25GbE. The cable provides a short-reach, fixed-assembly connection between servers, switches or network interface cards without the need for separate optical transceivers. Its passive copper design delivers a low-latency, low-power interconnect suitable for data center top-of-rack and intra-rack links.
Advantages
This passive SFP28 DAC cable offers a cost-effective alternative to optical modules for short-distance 25 Gigabit Ethernet links, reducing both component count and power consumption. The integrated SFP28 connectors simplify installation and minimize signal conversion overhead, which helps maintain low latency. The 3 m length provides flexibility for typical rack and cabinet layouts while keeping signal integrity for high-speed uplinks and server-to-switch connections.
Suitable for
Short-reach 25GbE connections between switches and servers
Top-of-rack and intra-rack data center interconnects
High-density networking where low power and low latency are required
Direct connections between network interface cards and switch ports
Key specifications
Connector type: SFP28 on both ends
Cable type: Passive twinax copper
Nominal length: 3 meters
Supported link speed: 25 Gigabit Ethernet
Typical applications: short-reach server-to-switch and switch-to-switch links
Power profile: passive (no active electronics in cable)
How to use
Insert each SFP28 connector into the corresponding SFP28 port on your switch, server or network adapter until the connector latches. Ensure that both devices support 25GbE over passive DAC cables and that ports are enabled and correctly configured in the network operating system. No separate transceivers, fibers or patch panels are required; the cable provides a direct copper connection. When removing the cable, release the latch before pulling to avoid damaging the connector or port.
Usage recommendations
For reliable performance, use this passive SFP28 DAC cable for links within racks or between adjacent racks where the 3 m length is adequate. Verify device compatibility with SFP28 passive copper DACs and keep the cable routed to avoid sharp bends or mechanical stress. In environments with higher electromagnetic interference, consider alternative cabling or shielded pathways to preserve signal integrity.
