## Summary description

Passive copper Direct Attach Cable (DAC) by CBO, model SFP28-DAC-2M, 2 meters long. Designed for SFP28 ports to provide a short-reach, low-latency 25GbE connection between compatible network devices such as switches, routers and NICs. Fixed-length copper twinax solution requiring no optical transceivers, suitable for rack-to-rack and intra-rack links to reduce cost and power consumption.

## Long description

The CBO SFP28 Passive Copper Direct Attach Cable 2 m SFP28-DAC-2M is a fixed-length twinax copper cable designed for SFP28 ports to deliver short-reach 25GbE connections. This passive DAC eliminates the need for optical transceivers, providing a low-latency, low-power link for direct device-to-device connections within racks or between adjacent racks. The 2 meter length makes it suitable for common data center topologies where short, high-bandwidth links are required.
Advantages
This passive SFP28 copper cable offers reliable signal integrity for 25GbE links while consuming less power than active optical solutions. The fixed twinax design reduces component count and simplifies installation since no separate transceivers are required. Its short-reach topology lowers overall solution cost and minimizes latency, making it efficient for high-throughput, low-latency networks.
Suitable for
Rack-to-rack and intra-rack connections in data centers
Interconnects between switches, routers and 25GbE NICs
Short-reach server uplinks and top-of-rack deployments
Environments where power and cost reduction are priorities
Key specifications
Interface: SFP28 to SFP28 compatible twinax copper
Data rate: 25 Gigabit Ethernet (25GbE)
Length: 2 meters
Type: Passive direct attach copper (DAC)
Use case: Short-reach, low-latency interconnects
How to use
Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the network devices until the latch engages. Ensure both devices support passive SFP28 DACs and 25GbE operation. No separate optical transceivers or additional configuration is typically required; once connected, verify link status in device management interfaces and adjust interface settings if necessary to match speed and duplex parameters.
Usage recommendations
For reliable operation, use this 2 m passive copper DAC in short-reach links within racks or between adjacent racks. Avoid sharp bends and excessive strain on the cable, maintain proper cable management to prevent stress on connectors, and confirm device compatibility with SFP28 passive DACs before deployment.
