## Summary description

CBO SFP28-DAC-1M is a 1 m passive copper DAC (Direct Attach Copper) cable designed for 25 Gbps SFP28 connections. It provides a short-reach, low-latency wired link between compatible SFP28 ports in switches, routers or servers. Ideal for data center Top-of-Rack and short intra-rack connections, it eliminates the need for separate transceivers and fiber, offering a cost-effective, power-efficient solution.

## Long description

The Copper DAC Cable CBO SFP28-DAC-1M is a 1 m passive Direct Attach Copper (DAC) cable engineered for 25 Gbps SFP28 connections. It provides a direct, low-latency electrical link between compatible SFP28 ports in switches, routers or servers, suitable for short-reach links inside racks and between adjacent equipment in data center environments. By combining connector and cable in a single assembly, this DAC cable removes the need for separate optical transceivers and fiber patch cords for short-distance interconnects.
Advantages
This passive SFP28 DAC cable delivers 25 Gbps data throughput with minimal latency and reduced power consumption compared with active or optical solutions over short distances. Its fixed 1 m length simplifies cable management in Top-of-Rack and intra-rack deployments. The integrated twinax construction and SFP28 connectors provide compatibility with equipment supporting SFP28 electrical interfaces, offering a cost-effective alternative for high-density, short-range interconnects.
Suitable for
Top-of-Rack connections between switches and servers
Intra-rack links for high-density network deployments
Short-reach uplinks in data centers and server rooms
Low-latency connections in storage and compute clusters
Key specifications
Data rate: 25 Gbps
Interface type: SFP28 to SFP28 (DAC)
Cable type: passive twinax copper
Length: 1 meter
Latency: low, direct electrical connection
Power consumption: passive, no additional power required
How to use
Ensure both ends of the network equipment support SFP28 electrical interfaces and are powered off or hot-pluggable according to vendor guidance. Insert each SFP28 connector into the corresponding port until it latches securely. Verify link status via the switch or server management interface and confirm the connection negotiates at 25 Gbps. For removal, release the connector latch and pull the cable straight out to avoid stressing the port.
Usage recommendations
Use this 1 m passive DAC cable for short-distance interconnects where optical transceivers are unnecessary. Avoid tight bends and excessive pulling; maintain bend radii recommended by equipment vendors. Verify compatibility with your switch or server firmware and, when deploying at scale, test one link before large rollouts to confirm link negotiation and performance.
