Product information

Description

The BlueLAN Alcatel-Lucent Q28-4S28-DAC-2M is a 2-meter passive direct attach breakout cable engineered for high-speed short-reach connections. One end terminates in a QSFP28 connector and the other end splits into four SFP28 connectors, supporting 100GBASE-CR4 and 25GBASE-CR operation modes. Constructed with AWG26 conductors, the cable is designed to deliver low insertion loss and consistent signal integrity for top-of-rack and aggregation layer links in data center and high-performance computing deployments.

Advantages

This breakout cable provides a compact and cost-effective solution for connecting a 100G QSFP28 port to four 25G SFP28 ports without active components. Its AWG26 construction balances flexibility with electrical performance, while the passive design reduces power consumption and eliminates the need for transceiver optics. The 2 m length offers a practical reach for within-rack and short inter-rack connections, and the standardized QSFP28-to-4xSFP28 pinout ensures interoperability with compatible switches and servers.

Suitable for

  • Top-of-rack switch to server aggregation where 100G breakouts to 25G are required
  • High-performance computing clusters needing short, low-latency links
  • Data center migration or consolidation projects that split 100G links into multiple 25G endpoints
  • Switch cascading and spine-to-leaf connections within the same rack or adjacent racks

Key specifications

  • Length: 2 meters
  • Connector types: QSFP28 (one end) to 4 × SFP28 (other end)
  • Supported standards: 100GBASE-CR4 and 25GBASE-CR
  • Cable construction: AWG26 conductors
  • Passive direct attach (no active electronics)
  • Typical use: Short-reach copper breakout connections within racks

How to use

Install the QSFP28 end into a compatible 100G port on a switch or network device and plug the four SFP28 ends into the target 25G ports on servers or line cards. Ensure that the host devices support passive direct attach breakout cables and the intended 100G-to-4×25G mapping. Route the cable to avoid tight bends and excessive strain; observe standard data center cabling practices for clear airflow and secure connector seating. No additional configuration is required on the cable itself, but verify link status and speed negotiation on connected devices after insertion.

Usage recommendations

Use this 2 m passive breakout cable for within-rack or adjacent-rack connections where short, reliable 100G-to-4×25G splitting is needed. Avoid installation in environments with high electromagnetic interference and do not exceed recommended bend radius for AWG26 copper assemblies. Confirm compatibility with switch firmware and port mapping before deployment to ensure proper link negotiation.
