BlueOptics QSFP-4SFP25G-CU2M Compatible BlueLAN Passive 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout Cable, 2m, AWG26

The BlueOptics QSFP-4SFP25G-CU2M is a high-performance, passive Direct Attach Breakout Cable (DAC) designed for 100 Gigabit Ethernet connectivity. It converts a single QSFP28 port into four independent 25 Gigabit SFP28 ports, making it ideal for high-density data center and enterprise networking environments. This cable is fully compatible with Cisco QSFP-4SFP25G-CU2M and other MSA-compliant equipment, ensuring seamless integration into existing infrastructures.

Advantages

Cost-effective and low-latency solution for 100G to 4x25G breakout applications. The passive copper design consumes no power and provides reliable signal integrity over 2 meters. Hot-pluggable QSFP28 and SFP28 connectors allow for easy installation and maintenance without network downtime.

Suitable for

• Data centers requiring high-density 100G connectivity
