Product information

Description

The BlueLAN QSFP28-4SFP28-DAC-2M is a passive direct-attach breakout cable designed to provide a 100GBASE-CR4 connection on one end and four separate 25G SFP28 connections on the other. With a 2 meter length and AWG26 wire gauge, this Black cable supports high-speed short-reach links between QSFP28 ports and multiple SFP28 ports in rack servers, switches and aggregation equipment. The cable is intended for use in dense networking environments where reliable, low-latency interconnects are required.

Advantages

The cable delivers a compact, low-power alternative to active optical modules by using a passive copper breakout that minimizes latency and does not require external power. Its integrated QSFP28 to 4×SFP28 configuration simplifies connectivity between 100G and 25G ports without additional transceivers. The AWG26 conductor specification and 2 m length balance signal integrity and flexibility for typical top-of-rack and middle-of-row deployments.

Suitable for

  • Interconnecting 100G QSFP28 ports to multiple 25G SFP28 ports in switches and routers
  • Top-of-rack and spine-leaf architectures in data centers
  • High-performance computing clusters requiring high-bandwidth short links
  • Equipment staging and lab environments for testing 25G/100G interfaces

Key specifications

  • Form factor: QSFP28 on one end, 4 × SFP28 on the other
  • Supported link rates: 100GBASE-CR4 (single end) and 4 × 25GBASE-CR (breakout)
  • Length: 2 meters
  • Conductor gauge: AWG26
  • Cable color: Black
  • Type: Passive direct-attach copper breakout cable

How to use

Connect the QSFP28 connector to the 100G-capable port on a switch or server. Insert each SFP28 connector into the corresponding 25G ports of target devices. Ensure both ends are fully seated and aligned with port guides to avoid mechanical strain. No additional power or transceivers are required for standard passive operation; the host ports must support passive DAC breakout connections and be configured for the intended 100G-to-4×25G mapping in device firmware or switch software.

Usage recommendations

Use the cable within short-reach topologies and keep cable runs within the specified 2 m length to preserve signal integrity. Avoid tight bends and excessive pulling force; maintain the minimum bend radius specified by equipment manufacturers. Verify compatibility with host hardware and firmware for passive DAC operation before deployment, and test link status after installation to confirm expected 25G lanes are active.
