## Summary description

CBO SFP28-DAC-2M is a 2-meter passive direct-attach copper (DAC) cable with SFP28 connectors designed for 25Gbps data links. It provides a low-latency, cost-effective short-reach connection between switches, NICs and servers without the need for optical modules. Suitable for data centers and rack-to-rack interconnects where power-efficient, reliable 25GbE links are required.

## Long description

CBO SFP28-DAC-2M is a 2 meter passive direct-attach copper cable with SFP28 connectors designed for 25Gbps Ethernet links. The cable provides a short-reach, low-latency connection between compatible switches, network interface cards and servers without requiring optical transceivers. Its passive design reduces power consumption and cost, making it suitable for dense rack environments and data center topologies where reliable 25GbE links are needed.
Advantages
The passive SFP28 DAC cable offers predictable performance for short-distance 25Gbps connections while avoiding the additional cost and power draw of optical modules. Its fixed 2 m length simplifies cabling planning for rack-to-rack or in-rack interconnects. With standardized SFP28 connectors, the cable ensures straightforward insertion into compatible ports and stable electrical signaling with minimal added latency.
Suitable for
Server-to-switch connections within racks
Switch-to-switch interconnects in the same rack or adjacent racks
High-density top-of-rack data center deployments
Short-reach 25GbE uplinks and aggregation links
Key specifications
Cable type: passive direct-attach copper (DAC)
Connector type: SFP28 on both ends
Nominal length: 2 m
Rated data rate: 25 Gbps
Use case: short-reach electrical interconnect
Latency: low, suitable for latency-sensitive links
Power: passive (no active components or additional power required)
How to use
Insert each SFP28 connector into the corresponding 25GbE SFP28 port on your network devices until the latch engages. Use the 2 m length to route the cable neatly within or between adjacent racks, avoiding tight bends and excessive strain. No module configuration is required beyond standard port settings on switches or NICs; the link should negotiate at 25Gbps when both ends support that speed. For removal, press the connector latch and pull straight out to avoid damaging the port.
Usage recommendations
Use the cable for short-distance 25GbE links where passive electrical connections provide cost and power advantages. Verify port compatibility and firmware settings on switches and NICs before deployment. Avoid sharp bends, kinking, or physical stress on the cable and ensure connectors are clean and fully seated to maintain signal integrity.
