QSFP28 100G Loopback Module .

This QSFP28 loopback module is designed for testing 100G ports in switches, NICs and other QSFP28-capable devices. It supports passive electrical loopback to verify signal continuity, link stability and port behaviour without requiring active optics. The QSFP28 loopback adapter emulates electrical tests across four channels for 100 Gbit/s QSFP28 ports and supports 40GBASE and 100GBASE Ethernet. It is MSA-compliant and meets IEEE 802.3 requirements for reliable performance and universal compatibility, performing electrical loopback tests for full 100G link validation. It ensures a consistent signal with 100-ohm impedance and low jitter for stable, reproducible results under real-world conditions. Connect it directly to the QSFP28 ports of switches, routers or NICs for inline port testing; its compact, energy-efficient design makes it an essential tool for network engineers and IT professionals in data centres as well as edge or on-premise installations.
