BlueOptics QTAPCABLE28-0.5M Compatible BlueLAN Passive 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout Cable, 0.5m, AWG26

The BlueOptics QTAPCABLE28-0.5M is a high-performance passive Direct Attach Copper (DAC) breakout cable designed for Chelsio compatible networking equipment. It enables seamless connectivity between a QSFP28 port and four SFP28 ports, supporting 100GBASE-CR4 to 4x25GBASE-CR data rates. Ideal for data centers and high-speed computing environments, this cable ensures reliable, low-latency transmission over a 0.5-meter length with AWG26 gauge construction.

Advantages

This breakout cable offers a cost-effective and power-efficient solution for high-bandwidth interconnects. Its passive design eliminates the need for external power, reducing overall system power consumption. The 0.5-meter length is perfect for short-range connections within a rack, minimizing cable clutter and improving airflow. BlueLAN compatibility ensures broad interoperability with Chelsio and other QSFP28/SFP28 systems.

Suitable for

• Data center top-of-rack to server connections
