Description
The 100G QSFP28 Male-to-Female DAC Extension Cable is a passive copper extension solution designed to extend existing QSFP28 connections in 100G network environments without replacing the original cable assembly. It features a QSFP28 male connector on one end and a QSFP28 female extension interface on the other, supporting up to 28.3125Gbps per channel across four channels for 100G-class short-distance connectivity. Available in 1m to 5m lengths, the cable uses a shielded metal connector structure and optimized electrical design to provide low insertion loss, low crosstalk, and reduced EMI. Its low-power architecture makes it suitable for data centers, high-performance computing, storage networks, testing environments, and other applications requiring additional reach for QSFP28 connections.
