## Summary description

CBO SFP28-DAC-1M is a 1-meter passive direct attach copper (DAC) cable designed for SFP28 ports and 25GbE links. It provides a fixed, low-latency physical connection between compatible network devices such as switches, routers, and NICs. Intended for short-reach interconnects in data centers, racks, and server rooms, it offers a cost-effective, power-efficient alternative to optical transceivers.

## Long description

The CBO SFP28 Passive Direct Attach Copper Cable 1m (SFP28-DAC-1M for 25GbE connections) is a 1‑metre passive SFP28 twinax copper cable engineered for short‑reach, high‑throughput links. It connects SFP28 ports to establish 25 Gigabit Ethernet links with minimal latency and low power consumption. Designed for use in data centers, server rooms and network racks, the cable provides a fixed physical interconnect between compatible switches, routers and network interface cards without the need for separate optical transceivers.
Advantages
This passive SFP28 DAC offers predictable electrical performance for 25GbE applications while consuming no additional power for signal conversion. Its short length supports stable, low‑latency connections and simplifies cabling within racks and between adjacent equipment. The integrated SFP28 form factor ensures plug‑and‑play compatibility with devices that support SFP28 passive DACs and reduces total cost of ownership compared with optical modules and transceivers.
Suitable for
 Short‑reach links between switches and top‑of‑rack devices
 Direct connections between servers and NICs supporting SFP28
 Patch connections inside data centre racks and equipment shelves
 Applications requiring low latency and low power interconnects
Key specifications
 Cable type: Passive twinax copper with integrated SFP28 connectors
 Length: 1 metre
 Data rate: 25 Gigabit Ethernet (25GbE)
 Form factor: SFP28 compatible
 Typical use: Short‑reach, in‑rack or adjacent‑rack interconnects
 Latency: Low, fixed‑function electrical link
 Power: Passive (no additional power for signal conversion)
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the two devices to be connected, ensuring the latch engages and the connector seats fully. Confirm that both devices are configured to use a 25GbE link and that firmware or driver support for passive DACs is enabled where applicable. Route the cable within the rack to avoid sharp bends and mechanical stress; avoid running the cable near high‑power or high‑temperature components. After installation, verify link status and speed via the device management interface.
Usage recommendations
Use this 1m passive SFP28 DAC for short, direct interconnects inside racks or between adjacent racks; check device compatibility lists before deployment and avoid exceeding recommended bend radii or exposure to excessive temperatures to maintain signal integrity and cable longevity.
