Designed for short-range 25GbE or compatible SFP28 connections between switches, routers and servers, it provides low-latency, cost-effective direct-attached connectivity without transceivers. Ideal for rack-to-rack or within-rack links where reliable, simple high-speed copper interconnect is required.

## Long description

CBO SFP28-DAC-1M is a 1 m passive copper direct attach cable with SFP28 connectors on both ends. It is designed for short-range 25GbE or other SFP28-compatible links between switches, routers and servers. The cable delivers a low-latency physical connection without the need for optical transceivers, making it a cost-effective option for rack-to-rack or within-rack interconnects where simple, high-speed copper connectivity is required.
Advantages
The passive 1 m copper design minimizes power consumption and eliminates transceiver compatibility concerns while providing the full electrical performance of SFP28 interfaces. By avoiding optical modules, the cable reduces overall link cost and simplifies installation. Its fixed length and robust SFP28 connectors offer predictable latency and stable signal integrity for short-distance 25GbE links in data center and enterprise environments.
Suitable for
 Short-range 25 Gigabit Ethernet links between switches
 Server-to-switch connections within the same rack
 Inter-rack connections in adjacent racks or cabinets
 High-density top-of-rack deployments requiring low-latency links
Key specifications
 Connector type: SFP28 to SFP28
 Media: passive copper twinax
 Length: 1 meter
 Supported data rates: up to 25 Gbps per lane (25GbE)
 Typical applications: direct-attach short-reach connections
 Physical form: fixed-length cable with integrated connectors
How to use
Insert each SFP28 connector into the corresponding transceiver slot on network equipment until it latches. Ensure both ports are configured for SFP28 passive DAC operation and that link settings (speed/auto-negotiation) match on both devices. No additional power or optical modules are required. For hot-plug capable equipment, the cable can be connected or disconnected while devices are powered, following standard data center procedures and observing anti-static precautions.
Usage recommendations
Use the cable for short, fixed-length connections where 1 m meets distance requirements. Avoid sharp bends and excessive pulling; maintain manufacturer-recommended bend radius and secure cable routing in racks or trays. Verify compatibility with the SFP28 ports on your switches and servers and confirm link status after installation.
