Loopback Tester

Plug-and-play loopback testers that exercise host ports of switches, NICs and modules at full speed.

MultiLane Loopback Testers emulate a transceiver while looping the high-speed signal back from the host into itself. They are an indispensable tool for switch and server manufacturing test, in-field troubleshooting and QSA/OSFP/QSFP MSA compliance verification.
