Other PCB Based Applications &
Active Optical Cable (AOC)
For PCB level of products such as active optical cables (AOC) and onboard optics (OBO), the die are attached directly onto a PCB. Multiple die such as a vertical-cavity surface-emitting laser (VCSEL) array, photodiode (PD) array, laser diode driver (LDD), and transimpedance amplifier (TIA) need to be attached on the PCB. The final lens attachment is done passively with 1.5 micron and 3 micron accuracy machines.
