Optical modules is an important part of optical fiber communication.The surface of the printed board of optical modules has high-speed transmission signal lines,and high reliability and low signal loss are the new requirements of 5G optical module products.Controlling impedance and signal loss is the key to do a good job in optical module products.Taking the 14-layer 1.6T high-speed optical module printed board products as an example,control operations are analyzed in terms of design,process,and peoduct quality,so as to provide relevant reference for technical workers in the industry.
