## Summary description

Passive SFP28 direct attach copper (DAC) cable by CBO, model SFP28-DAC-1M-CO-BL, 1 meter length. Designed for short-reach 25GbE connections between SFP28 ports on switches, NICs and servers. Provides a cost-effective, low-power wired link for rack-level interconnects and top-of-rack deployments where a short, reliable copper connection is required.

## Long description

The CBO SFP28 Passive Direct Attach Copper Cable 1m is a 1‑metre passive SFP28 DAC cable designed for short‑reach 25GbE connections between SFP28 ports on switches, network interface cards and servers. It provides a low‑latency, low‑power wired link suitable for rack‑level interconnects and top‑of‑rack deployments where a compact and reliable copper connection is required. The cable integrates SFP28 connectors on both ends and is intended for direct attachment without separate transceiver modules.
Advantages
This passive SFP28 DAC cable offers direct electrical connectivity with minimal signal processing, reducing power consumption compared with active or optical solutions. The fixed 1 m length simplifies rack planning and maintains consistent performance for short distances. Its SFP28 form factor ensures compatibility with equipment that supports SFP28 ports, enabling plug‑and‑play installation and predictable latency and throughput for 25GbE links.
Suitable for
 Short‑reach 25GbE links between top‑of‑rack switches and servers
 Direct connections between NICs and switch ports in data center racks
 High‑density rack deployments requiring low‑power, low‑latency links
 Environments where a cost‑effective copper interconnect is preferred over optical cables
Key specifications
 Interface: SFP28 to SFP28 (direct attach copper)
 Data rate: 25 Gigabit Ethernet
 Length: 1 metre
 Cable type: Passive twinax copper
 Typical use: Short‑reach rack and top‑of‑rack interconnects
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on your switch, server or NIC until the latch clicks. Ensure devices are powered off or follow hot‑plug guidelines from equipment manufacturers when connecting or disconnecting. Verify link status and speed on the devices after insertion; most systems will auto‑negotiate 25GbE when supported. Route the cable to avoid sharp bends and excessive strain on the connectors.
Usage recommendations
Use this 1 m passive SFP28 DAC cable for short, fixed connections within the same rack or adjacent racks. Avoid using the cable beyond its recommended short‑reach distance, and prevent exposure to high temperatures or mechanical stress. Check switch and NIC compatibility lists for SFP28 passive DAC support to ensure proper operation.
