## Summary description

Passive SFP28 copper Direct Attach Cable (DAC) by CBO, model SFP28-DAC-2M, 2 meters length. Designed for short-reach 25Gbps connections between SFP28 ports in switches, NICs and storage devices. Provides low-latency, energy-efficient direct copper link without transceivers, suitable for data center top-of-rack and server-to-switch interconnects.

## Long description

The CBO SFP28 Passive Copper Direct Attach Cable 2 m (model SFP28-DAC-2M) is a 2‑metre passive SFP28 copper cable designed for short‑reach 25 Gbps links between SFP28 ports. It provides a direct copper connection without separate optical transceivers, enabling low latency and reduced power consumption for top-of-rack, server-to-switch and storage interconnects in data center environments. The cable is fitted with SFP28 form-factor connectors on both ends for plug-and-play installation in compatible switches, NICs and storage devices.
Advantages
The passive direct attach design reduces component count and power draw compared with active optical solutions, while offering predictable latency and cost-effective short-distance connectivity. Its SFP28 connectors ensure mechanical compatibility with 25Gbps ports and simplify deployment by eliminating the need for separate transceivers. The fixed 2 m length is convenient for rack-mounted cabling between adjacent equipment and helps maintain clean cable management in dense deployments.
Suitable for
Top-of-rack switch to server 25Gbps connections
Server-to-storage device interconnects in data centers
Short-reach links inside network cabinets and racks
Environments prioritizing low latency and reduced power consumption
Key specifications
Interface: SFP28 to SFP28 (copper direct attach)
Data rate: 25 Gbps per channel (single-lane 25Gbps)
Length: 2 metres
Type: Passive copper direct attach cable
Typical applications: short-reach interconnects for switches, NICs and storage
Form factor: SFP28 compatible plug-in connectors
How to use
Install the cable by inserting each SFP28 connector into the SFP28 port of the two devices to be linked, ensuring the connector latch engages fully. No separate transceivers, power sources, or configuration steps are required on the cable itself; device ports should be configured as needed by the switch or host operating system. Verify link status and speed on both endpoints after insertion and monitor for any port or link errors in your management interface.
Usage recommendations
Use the 2 m passive DAC for short, direct connections within the same rack or between adjacent racks. Avoid tight bends and excessive strain on the cable; maintain recommended bend radius and secure the cable to prevent movement. Confirm compatibility of SFP28 ports and firmware with passive DAC modules in your equipment vendor documentation before deployment.
