神马影院第九影院 - Optical Transceiver
USI has industry-leading capabilities in high-speed signal integrity and power integrity (SI/PI) design, as well as advanced thermal simulation and optical simulation using Zemax. In addition, we have strong expertise in high-speed PCB design utilizing mSAP and substrate PCB technologies. USI also operates dedicated optical communication laboratories for module performance verification, including optical eye diagram measurements using high-speed sampling scopes and bit error rate testing using BERT equipment.
Beyond R&D strengths, USI’s manufacturing capabilities for optical modules include high-density SMT processes, KGD flip-chip, and die/wire bonding production lines with full testing and validation. The company also supports optical device assembly along with optical module testing capabilities. These end-to-end capabilities enable USI to deliver complete solutions from design and development to high-volume manufacturing.
