光調制器

 FEATRES
 Ti-diffusion process
 Single-drive technology
 50 Ω design
 Low optical reflections
 Low drive voltage
 Low insertion loss
 APPLICATIONS
 Digital telecommunication
 SONET / SDH
 Medium and long haul transmission
 DWDM and TDM transmission

功能:在光纖通信系統中,把要傳送之信號加載到光波上的過程就是調制。光調制器就是實現從電信號到光信號的轉換的元件。
