Applications
The loopback module is a 400Gbps Quad Small Form Factor Pluggable QSFP-DD loopback module for testing QSFP-DD transceiver ports on host/system boards.
By substituting a full-featured QSFP-DD transceiver, the electrical loopback provides a cost effective method for QSFP-DD port testing. We suggest test 400GBase-ZR and OSFP 800G optics before using.
