02 Integrated Test Head

In addition to traditional discrete Test platforms, Semight also offers highly integrated test heads

· MTP4101/MTP4102/MTP4104, support 10Gbps~400Gbps optical module test

· MTP8102, support 800Gbps OSFP/QSFP-DD optical module test

Test Head features

The Test Head integrates a bit error analyzer (BERT), MCB test board, and TEC temperature cycle control system to test the bit error of high-speed optical modules at different temperatures

· Integrated MCB test card for flexible and fast DUT MCB replacement

· Integrated error meter platform eliminates additional cable connections, further reducing test bench space and cost

· Integrated TEC temperature control system, support module temperature cycle test

Test Head supports module type and number of parallel tests
