Introduction to Optical Module PCB Board
Definition: An Optical Module PCB is the internal circuit board of a transceiver (like SFP, QSFP, or OSFP) responsible for converting electrical signals to optical signals and vice versa. Critical Metrics: Signal integrity (insertion loss, return loss) and thermal management are the two. The Printed Circuit Board (PCB) at the heart of these modules is no longer a simple substrate but a highly engineered system. Optical modules are used in applications including fiber-optic communication systems, data centers, and high-speed network systems to transmit and receive optical signals for data. With the increasing demand for massive parallel data computation in AI large-scale model training and inference, the world is facing greater demands for network bandwidth. The photonic layer is a planar waveguide that acts as the data transmission component, while the electrical parts serve the processing function.
