Product information

Description

CBO SFP28-DAC-2M is a 2 meter passive Direct Attach Copper (DAC) cable with SFP28 connectors on both ends, engineered for short-range 25GbE and compatible SFP28 links. The cable provides a direct electrical connection between network devices without the need for separate optical transceivers, making it suitable for dense rack-to-rack or within-rack deployments where link distances are limited and cost and latency are important considerations.

Advantages

The passive copper design delivers low latency and stable signal integrity for short interconnects while eliminating the need for additional transceivers. Its fixed 2 m length simplifies planning for within-rack or adjacent-rack connections and reduces component count. SFP28 form-factor connectors ensure compatibility with SFP28 ports on switches, servers and network interface cards that support passive DACs.

Suitable for

  • Short-range 25GbE links between switches in the same rack
  • Connections from servers to top-of-rack switches
  • High-density network deployments where cost-effective cabling is needed
  • Low-latency interconnects for data center aggregation and leaf-spine topologies

Key specifications

  • Connector type: SFP28 to SFP28
  • Length: 2 meters
  • Cable type: Passive Direct Attach Copper (DAC)
  • Supported data rate: 25 Gbit/s (compatible with 25GbE links)
  • Usage: Short-range, within-rack or adjacent-rack interconnects

How to use

Install the DAC cable by inserting each SFP28 connector into the corresponding SFP28 port on your network devices until it clicks into place. Ensure both devices support passive DAC connections at the specified data rate and that firmware or compatibility lists permit direct attach copper. Route the cable to avoid excessive bending and secure it within the rack to prevent strain on the connectors. No external power or transceiver modules are required.

Usage recommendations

For reliable operation, use this 2 m passive DAC for short-distance links inside the same rack or between adjacent racks. Verify device compatibility with passive SFP28 DACs and confirm port settings for 25GbE operation. Avoid sharp bends, excessive tensile force and electromagnetic interference sources to maintain signal quality.
