QSFP28 100G passive loopback

Description

QSFP28 100G Passive Loopback Module – Diagnostic and Validation Tool for High-Speed Ethernet and InfiniBand Systems

The QSFP28 100G Passive Loopback Module, built to the SFF-8665 MSA specification, is a hot-pluggable diagnostic device designed to simulate a fully functional transceiver for testing and validating 100Gbps QSFP28 ports. Ideal for system development, production testing, and thermal profiling, this module supports 25Gbps per lane across four lanes, enabling full-speed loopback without active components.
