Product information

Description

CBO DAC Cable QSFP28-DAC-3M is a 3 meter passive copper Direct Attach Cable designed for QSFP28 ports. It provides a short-reach, low-latency 100GbE connection between switches, servers or network appliances. The cable plugs directly into QSFP28 transceivers and requires no external power or optical modules, delivering a cost-effective and energy-efficient link for data center and rack-to-rack interconnects.

Advantages

The passive copper design offers low latency and predictable signal performance for short-distance connections. Being a direct attach solution, the cable eliminates the need for separate transceivers or powered optics, reducing both initial hardware cost and ongoing energy consumption. The fixed 3 m length simplifies cable management between adjacent racks or within server chassis and supports standard QSFP28 port form factors for compatibility with a wide range of networking equipment.

Suitable for

  • 100 Gigabit Ethernet short-reach links between switches
  • Server-to-switch connections in data centers
  • Rack-to-rack interconnects within the same room or adjacent rows
  • Connecting network appliances and storage systems that support QSFP28

Key specifications

  • Interface: QSFP28 to QSFP28
  • Length: 3 meters
  • Media type: Passive copper direct attach
  • Supported data rate: 100 Gigabit Ethernet
  • Connector type: QSFP28 form factor
  • Typical application: Short-reach data center and rack interconnects

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on your switch, server or appliance until it seats securely. Ensure ports are compatible with passive DACs and that devices are powered and configured for 100GbE operation. No external power or additional optical modules are required. For removal, depress the connector latch (if present) and pull straight out to avoid stressing the cable or port.

Usage recommendations

Use the cable for short-distance interconnects up to 3 meters within the same rack or between adjacent racks. Avoid tight bends and maintain manufacturer-recommended bend radius to preserve signal integrity. Verify switch and server compatibility with passive QSFP28 Direct Attach Cables in device documentation before deployment.
