Ideal for rack‑to‑rack and top‑of‑rack connections where a cost‑effective, reliable copper link is required.

## Long description

CBO SFP28-DAC-1M is a 1-meter passive copper Direct Attach Cable (DAC) with SFP28 connectors on both ends, engineered for short-reach 25GbE and compatible SFP28 links. The cable provides a direct electrical connection between SFP28 ports and is intended for high-density environments such as server racks and switch-to-switch interconnects where compact cabling, low latency and low power consumption are priorities. Its 1 m length makes it suitable for rack-to-rack and top-of-rack connections inside data centers and network closets.
Advantages
The passive copper design delivers low latency and minimal power overhead compared with active optical or active copper assemblies. SFP28 connector compatibility ensures a standardized interface for 25GbE ports and compatible transceiver slots. The fixed-length 1 m assembly reduces the need for individual transceivers and fiber patching, simplifying deployment and lowering total cost of ownership for short-reach links. The cable’s compact profile and robust terminations facilitate dense port layouts in switches and servers.
Suitable for
Short-reach 25GbE links between servers and top-of-rack switches
Switch-to-switch connections within the same rack or adjacent racks
High-density data center environments with constrained rack space
Storage network interconnects requiring low latency and predictable performance
Key specifications
Connector type: SFP28 on both ends
Cable type: Passive copper direct attach
Supported data rate: 25 Gbit/s (25GbE) and compatible SFP28 speeds
Length: 1 meter
Form factor: Twinax DAC with integrated connectors
Typical use: Short-reach server, switch and storage interconnects
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on network equipment until the latch engages. Ensure ports are powered down or follow hot‑plug guidelines from the equipment manufacturer if connecting live. Verify link status and speed on both devices after insertion and configure network interfaces as required. For removal, depress the connector latch and withdraw the cable carefully to avoid stressing ports or nearby components.
Usage recommendations
Use this 1 m passive DAC for direct, short-distance links inside racks or between adjacent racks. Avoid sharp bends and mechanical stress on the cable; maintain bend radius recommended by the equipment vendor. For longer reaches or where electrical isolation is required, select fiber optic transceivers or active copper alternatives instead.
