## Summary description

CBO SFP28-DAC-1M is a 1‑meter passive Direct Attach Copper (DAC) SFP28 cable designed for short‑reach 25GbE connections. It provides a plug‑and‑play copper link between SFP28 ports for switches, servers and network appliances without the need for transceivers. Ideal for data center top‑of‑rack and server interconnects where cost‑effective, low‑latency connectivity is required.

## Long description

CBO SFP28-DAC-1M is a 1-meter passive Direct Attach Copper (DAC) SFP28 cable engineered for short-reach 25GbE connectivity. It creates a direct copper link between two SFP28 ports, enabling plug-and-play installation for switches, servers and network appliances without separate optical transceivers. The cable is intended for cost-efficient, low-latency interconnects in data center top-of-rack and server-to-server deployments where short distance, high-bandwidth links are required.
Advantages
The passive DAC design offers low power consumption and minimal latency compared with active optical solutions. Its one-piece copper construction reduces component count and simplifies installation, while the SFP28 form factor ensures compatibility with standard 25GbE SFP28 ports. The fixed 1 m length is suitable for compact rack layouts and short-path connections, providing a reliable, maintenance-free physical link for high-throughput applications.
Suitable for
Top-of-rack switch to server connections in data centers
Server-to-server links within the same rack or adjacent racks
High-bandwidth, low-latency short-reach interconnects
Switch stacking or uplink connections over short distances
Key specifications
Interface: SFP28 to SFP28
Rated data rate: 25 Gigabit Ethernet (25GbE)
Cable type: Passive twinax copper assembly
Length: 1 meter
Power: Passive operation (no external power required)
Latency: Low electrical latency suitable for high-performance networking
Form factor: SFP28 connector housing
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the devices until the latch engages. No additional configuration or transceiver modules are required; devices typically recognize the link automatically and negotiate the 25GbE connection. For optimal performance, ensure both endpoints support 25GbE over SFP28 and that the cable length fits the intended rack or chassis layout.
Usage recommendations
Use the DAC cable for short-distance links inside racks or between adjacent racks. Avoid tight bends and excessive pulling; maintain manufacturer-recommended bend radius and secure the cable to prevent mechanical stress. Verify compatibility with device firmware and port settings before deployment, and consider environmental factors such as airflow and temperature in dense installations.
