Optical modules will go through strict testing and quality inspection procedures before shipment, such as material testing, parameter testing, aging testing, real machine testing, end-face testing, etc. The explosive growth of AI infrastructure has created unprecedented demand for high-speed optical modules, straining global supply chains and raising critical questions about quality assurance. The results of all test. As optical modules are employed for high-speed data transmission and optoelectronic conversion, the manufacturing quality of their PCBs directly impacts the performance, stability, and reliability of the optical modules. Optical module PCB design demands exceptional accuracy to ensure stable and. A solution for accurately measuring the Latency of PAM4 optical modules is required. Potential source of time error in complex digital parts of pluggables. Higher bit rates (50 Gb/s and higher) and adoption of advanced modulation formats (PAM-4 or Coherent), require complex digital signal. With the widespread adoption of fiber optic networks and the rapid advancement of optical communication technology, the demands for the quality of optical modules have become increasingly stringent. LPO optical modules adopt linear direct-drive.
