Product information

Description

CBO DAC Cable SFP28-DAC-0.5M is a 0.5 m passive copper direct attach cable designed for short-reach 25GbE SFP28 connections. The cable provides a direct electrical link between SFP28 ports on switches, network interface cards (NICs) or routers without the need for separate optical transceivers. Its compact length and passive construction make it suitable for within-rack and adjacent-rack connections where fixed, low-latency links are required.

Advantages

The passive copper design offers low power consumption and minimal signal latency compared with active modules or optic links. At 0.5 m length the cable minimizes signal attenuation and ensures reliable 25GbE throughput for short-distance interconnects. Its integrated SFP28 connectors simplify installation and reduce component count, eliminating the need to purchase and manage separate transceivers and fiber patch cords.

Suitable for

  • Short-distance 25GbE links between switch ports
  • Connections between NICs and top-of-rack or leaf switches
  • Within-rack server-to-switch cabling
  • High-density rack environments requiring fixed short cables

Key specifications

  • Interface: SFP28 to SFP28 compatible
  • Nominal data rate: 25 Gigabit Ethernet
  • Length: 0.5 m (fixed copper cable)
  • Cable type: Passive twinax copper
  • Typical use: Short-reach direct attach
  • Latency: Low, electrical direct-attach characteristics

How to use

Ensure both network devices support SFP28 direct attach copper connections and are configured for 25GbE operation. Power down or follow hot-plug guidance from your equipment vendor, then insert each SFP28 connector into the corresponding port until it latches. After connection, verify link status and negotiated speed in the device management interface. Remove the cable by depressing the release tab on each connector and pulling straight out to avoid connector damage.

Usage recommendations

Use this 0.5 m passive DAC for rack-to-rack or within-rack short links where a fixed copper connection is acceptable. Avoid excessive bending of the cable near the connectors and maintain adequate airflow in dense racks. Confirm vendor compatibility lists if equipment OEM interoperability is required.
