Photonic modules play a pivotal role in high-speed communications due to their photoelectric signal conversion. The design of the PCB mainboard for photonic modules must meet special requirements such as high-speed transmission, Wärmeableitung, PCBA-Montage, and hot-plugging, setting it apart from ordinary PCBs.
The PCB of photonic modules is a key component for achieving photoelectric conversion, playing a crucial role in communication systems. It can convert electrical signals into optical signals or vice versa, ensuring efficient and long-distance data transmission through fiber optics.
OPTISCHE MODUL -PCB
When designing the PCB for photonic modules, factors like signal integrity, Thermalmanagement, and electromagnetic compatibility must be fully considered to ensure stable and reliable operation in high-speed, high-density data transmission environments.
