About the StarTech QSFP28 Loopback Module, 100G Passive QSFP28 Loopback Adapter, QSFP Port Tester, 100G QSFP Loopback Test Plug - MSA Compliant

This 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.

Test 100G QSFP28 Connections

The QSFP28 Loopback Adapter 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.

Accurate Signal Diagnostics

Perform electrical loopback testing for full 100G link verification. Ensure consistent signaling with 100Ω impedance and low jitter for stable, repeatable test results under real-world conditions.

For Enterprise Network Switches

Connect 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 pros in data centers and edge or on-prem installations.
