Product information

Description

Passive copper DAC cable CBO QSFP28-4SFP28-DAC-3M is a 3-meter direct-attach cable engineered to connect a single QSFP28 port to up to four SFP28 ports. It provides a fixed physical link with low latency and minimal power consumption for short-reach 100G to 4×25G or similar breakout configurations. The cable is intended for use in rack-mounted networking equipment such as switches, routers and servers where reliable, plug-and-play connectivity is required.

Advantages

This passive DAC cable offers low insertion loss and deterministic latency suitable for high-speed, short-distance links in data centre environments. Its passive copper construction eliminates the need for additional power or transceivers at each end, reducing operational power and heat. The cable’s breakout design simplifies linking a 100G QSFP28 interface to multiple 25G SFP28 ports without additional breakout modules, enabling compact, cost-efficient deployments.

Suitable for

  • Top-of-rack and adjacent rack connections in data centres
  • Connecting QSFP28 ports to multiple SFP28 ports for breakout configurations
  • Short-reach links between switches, routers and servers within the same rack or nearby racks
  • Low-latency, high-throughput 100G networking applications

Key specifications

  • Length: 3 meters
  • Connector configuration: QSFP28 to 4 × SFP28 (breakout)
  • Media type: passive copper direct-attach
  • Data rates supported: 100G to 4×25G breakout or equivalent 25G links
  • Typical use: short-reach links within racks and between adjacent racks
  • Form factor: direct-attach cable with fixed connectors

How to use

Install the cable by firmly inserting the QSFP28 end into the host QSFP28 port and each SFP28 plug into the corresponding SFP28 ports on the target device. Ensure devices are powered down or ports are in a safe state if required by your equipment’s installation procedure, then power up and verify link status through the device management interface. No additional modules or power supplies are required for the passive copper DAC; the connection is plug-and-play on compatible ports. Verify link speed and lane mapping on the switch or server to confirm the intended breakout configuration is active.

Usage recommendations

Use this DAC cable for short-distance, high-speed connections inside racks or between adjacent racks. Avoid running the cable near sources of strong electromagnetic interference and do not exceed the bending radius specified by the manufacturer to maintain signal integrity and mechanical reliability.
