Loopback Testers

Driven by the most stringent signal integrity and robustness from our Tier-1 customers, our team delivers the industry’s most advanced loopback testers — SmartLoop, emulating the copper cable and Optical module performance for InfiniBand and Ethernet switch/Network Interface Card/Ethernet port testing up to 2000+ mating cycles. Our SmartLoop series have saved the leading switch makers or Hyperscalers million dollars every year when the production ramps up for millions of ports and switches are shipped with the consistent performance.

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

Loopback testers emulate the copper cable/optical module signal integrity and validate the ASIC performance
