About this product
The QSFP28 Loopback Module is designed for testing 100G ports in switches, NICs, and other QSFP28-equipped devices. It supports passive electrical loopback for verifying signal continuity, link stability, and port behavior without requiring active optics. The module emulates 4-lane electrical testing for QSFP28 ports operating at 100Gbps and supports 40GBASE and 100GBASE Ethernet. It is MSA compliant and meets IEEE 802.3 requirements for reliable performance and universal compatibility. The module ensures consistent signaling with 100Ω impedance and low jitter for stable, repeatable test results under real-world conditions. It connects directly to QSFP28 ports on switches, routers, and NICs for inline port testing. Compact and low-power, it is an essential tool for network technicians and IT professionals in data centers and edge or on-prem installations.
