BlueOptics 100G-Q28-S28-C-0501-RU 5 m QSFP28 to 4x SFP28 Direct Attach Copper Breakout Cable - Black

The BlueOptics 100G-Q28-S28-C-0501-RU is a high-performance direct attach copper (DAC) breakout cable designed for 100 Gigabit Ethernet and InfiniBand applications. It features a QSFP28 connector on one end and four SFP28 connectors on the other, enabling seamless connectivity between 100G ports and four 25G ports. With a length of 5 meters and a passive copper design, this cable provides reliable, low-latency data transmission for data center and high-performance computing environments.

Advantages

This breakout cable offers a cost-effective and power-efficient solution for high-speed network interconnects. Its passive design eliminates the need for external power, while the 26 AWG wire gauge ensures optimal signal integrity over the 5-meter distance. The cable is hot-pluggable and MSA compliant, guaranteeing interoperability with standard QSFP28 and SFP28 ports.
