Loopback Testers

Wandtec offers the industry’s most robust loopback testers, SmartLoop, emulating the copper cable and Optical module signal integrity performance for Ethernet switch/Network Interface Card/Ethernet port testing up to 2000+ mating cycles. 

Our cost saving 0-dB power LC loopback testers help industry’s equipment and device makers to go-to-market by reducing the consumable testing cost 50%+.

Our loopback supports 10G-800G Ethernet testing with technical compliance to IEEE/OIF-CEI standards in the form factor of SFP/QSFP/SFPDD/DSFP/QSFPDD/OSFP. 

Loopback testers emulate the copper cable/optical module signal integrity and validate the port functions.
