## Summary description

CBO SFP28-DAC-2M is a 2‑meter passive copper DAC cable with SFP28 connectors on both ends. Designed for short‑reach 25GbE interconnects between switches, servers and NICs, it provides a low‑latency, energy‑efficient alternative to optical transceivers. Ideal for data center top-of-rack links, server cages and high‑density rack deployments.

## Long description

CBO SFP28-DAC-2M is a 2-meter passive copper direct attach cable with SFP28 connectors on both ends, engineered for short-reach 25GbE links. It connects switches, servers and network interface cards (NICs) with minimal latency and reduced power consumption compared to optical transceivers. The cable is intended for high-density rack environments and top-of-rack interconnects where cost-efficiency and signal integrity over short distances are priorities.
Advantages
The passive copper design delivers low latency and stable 25GbE performance without the need for separate transceivers, lowering both equipment and operational costs. Its SFP28-to-SFP28 plug-and-play form factor simplifies installation and reduces the number of spare parts required. The 2 m length fits typical data center layouts, offering reliable electrical signaling for short-distance links while avoiding the power overhead associated with active optical solutions.
Suitable for
 Top-of-rack (ToR) switch-to-switch connections in data centers
 Server-to-switch or server-to-NIC short links
 High-density rack deployments and server cages
 Environments where low latency and energy efficiency are required
Key specifications
 Connector type: SFP28 to SFP28
 Cable type: Passive copper direct attach
 Data rate: 25 Gigabit Ethernet (25GbE)
 Length: 2 meters
 Typical use: Short-reach interconnects in racks and adjacent equipment
 Form factor: Dual-ended plug-and-play assembly for host ports
How to use
Insert each SFP28 connector into the SFP28 slot of the two devices to be linked, ensuring the connectors are aligned and fully seated until the retention latch engages. Confirm that connected devices support passive DAC cables and 25GbE operation; the link should be detected automatically and negotiate the appropriate settings. For initial deployment, verify link status and speed in the device management interface and monitor for errors during early operation.
Usage recommendations
Route the cable to avoid tight bends and mechanical strain; maintain the minimum bend radius recommended by the manufacturer. Use the 2 m length for adjacent racks or within the same rack to ensure optimal signal integrity. Keep connectors clean and handle them by the connector housing to prevent contamination. Verify compatibility with device vendor documentation when mixing brands or using NICs and switch models with specific DAC support lists.
