Product information

Description

BlueOptics DAC Cable CBO Meraki QSFP28-4SFP28-DAC-3M 3M Length is a direct attach copper (DAC) cable designed to connect QSFP28 ports to four SFP28 ports within high-speed network environments. The cable provides a fixed 3-meter length for short-reach interconnects inside racks and between adjacent racks, offering a cost-effective, low-latency physical connection for 100G-to-4x25G breakout applications.

Advantages

The DAC cable delivers low electrical latency and predictable performance for 100G QSFP28 to 4×25G SFP28 conversions. As a passive copper assembly it requires no external power or optics modules, which simplifies installation and reduces operating costs. The fixed 3 m length ensures a reliable, stable link for short-range connections while minimizing signal attenuation typical of longer runs.

Suitable for

  • Breakout of a 100G QSFP28 port into four independent 25G SFP28 links
  • Interconnects within the same rack or between adjacent racks in data centers
  • High-throughput switching and server uplinks where short-reach copper connectivity is acceptable

Key specifications

  • Connector type: QSFP28 to 4 × SFP28
  • Transmission medium: Direct attach copper (DAC)
  • Supported data rate: 100G (breakout to 4 × 25G)
  • Cable length: 3 meters
  • Form factor: Passive twinax assembly for short-reach interconnects

How to use

Insert the QSFP28 end into the 100G QSFP28 port on the source device and plug the four SFP28 ends into the target devices or ports. Ensure ports are powered down or follow hot-swap guidelines from your hardware vendor if applicable. Verify that the host devices support QSFP28 to 4×SFP28 breakout mode and configure interfaces in the switch or router operating system as needed for aggregated or independent 25G links.

Usage recommendations

Use this 3 m DAC cable for intra-rack and adjacent-rack connections where short, low-latency links are required. Confirm compatibility with your network equipment for QSFP28 breakout functionality and observe bend-radius and handling guidelines to maintain cable integrity and signal performance.
