The passive cable delivers power-efficient, cost-effective connectivity with simple plug-and-play installation.

## Long description

CBO SFP28-DAC-2M is a 2 meter Direct Attach Copper (DAC) cable designed for SFP28 ports. The cable provides a fixed copper connection for 25GbE and compatible SFP28 networking equipment, optimized for short-reach links between switches, servers and network interface cards. As a passive cable assembly it offers a low-latency, power-efficient alternative to optical transceivers for rack-to-rack and chassis-to-chassis interconnects within data centers and server rooms.
Advantages
The DAC cable delivers reliable electrical connectivity with minimal insertion complexity: plug-and-play operation without additional modules or optics. Its short, direct copper construction results in low latency and reduced power consumption compared with active optical solutions. The fixed length and rugged connector housings provide predictable signal integrity and mechanical stability for high-density topologies.
Suitable for
Short-reach 25GbE links between switches and servers
Direct connections between server NICs and top-of-rack switches
High-density patching in data center racks and network cabinets
Environments where low latency and power efficiency are required
Key specifications
Connector type: SFP28 to SFP28 compatible copper twinax
Cable length: 2 meters
Supported data rate: 25 Gbit/s (25GbE) and compatible SFP28 rates
Transmission medium: passive copper twinax
Typical use case: short-reach interconnects (rack-to-rack, server-to-switch)
Installation: hot-pluggable, no additional power or transceivers required
How to use
Ensure SFP28 ports on both devices are powered and compatible with passive DAC assemblies before inserting the cable. Align the connector latches with the port and push until the latch clicks to secure the connection. For removal, depress the latch and pull the connector straight out. Route the cable to avoid sharp bends and mechanical stress; maintain the specified bend radius to preserve signal integrity. No configuration is required at the cable level beyond verifying link parameters on connected devices.
Usage recommendations
Use this DAC cable for short, fixed-length connections where cost and power efficiency are priorities. Avoid running the cable through areas with high electromagnetic interference, and do not exceed its bend radius. Verify compatibility with device firmware and port optics settings when integrating into mixed transceiver environments.
