The QSFP-100G-LB loopback module is a 100Gbps Quad Small Form Factor Pluggable QSFP28 loopback module for testing QSFP28 transceiver ports on host/system boards. By substituting a full-featured QSFP28 transceiver, the electrical loopback provides a cost effective method for QSFP28 port testing.
Note: The FS P/N is changed from Q28-LB to QSFP-LOOP-100G, but the product is the same. Only the FS P/N has been changed.

Thanks for reaching out, FS.com has had excellent service since we opened our account – I plan to continue ordering cables, jumpers and modules when needed.
Thanks for the information on the switches, I will keep that in mind for when we need to order network equipment in the future.
