Product information

Description

The BlueLAN QFX-Q-S-DAC-2M is a passive direct-attach breakout network cable that connects a single QSFP28 port to four SFP28 ports. Designed for short-range, high-throughput links, this 2-meter cable supports 100GBASE-CR4 and 25GBASE-CR electrical standards and uses AWG26 conductors to provide low insertion loss and consistent signal integrity in rack-to-rack and within-rack deployments. The cable is intended for high-density switch and server interconnects, enabling consolidation of four 25 Gbit/s lanes into a single 100 Gbit/s interface without active components.

Advantages

The breakout design simplifies migration and port consolidation by allowing direct connectivity between QSFP28 and multiple SFP28 ports while avoiding additional transceivers. Passive construction reduces power consumption and heat generation compared with active or optical transceivers. With a 2 m length and AWG26 wiring, the cable delivers predictable electrical performance for short-reach links commonly found in data centers and high-performance computing racks.

Suitable for

  • 100G switch to 4×25G server or NIC connections
  • High-density top-of-rack and middle-of-row networking
  • Short-reach interconnects inside racks and between adjacent racks
  • Migration paths from 25G infrastructures to consolidated 100G ports

Key specifications

  • Connector type: QSFP28 to 4×SFP28 breakout
  • Supported standards: 100GBASE-CR4 and 25GBASE-CR
  • Length: 2 meters
  • Conductor gauge: AWG26
  • Passive direct-attach construction (no active electronics)
  • Typical application: short-reach copper interconnects

How to use

Insert the QSFP28 end into a compatible 100G switch or adapter port and plug the four SFP28 ends into the target server or NIC SFP28 ports. Ensure ports and devices support passive DAC operation and the listed electrical standards before installation. Route the cable to avoid sharp bends and excessive tension; maintain manufacturer-recommended bend radius around cable pathways. Verify link status and speed on connected devices after insertion to confirm proper operation.

Usage recommendations

Use this passive 2 m breakout cable for short, high-throughput connections in data center environments. Avoid using it for extended distances beyond the supported short-reach electrical specifications. For environments requiring extended reach, active cables or optical transceivers with fiber are recommended.
