Working principle of optical transceivers and optical modules
At the heart of every optical transceiver lie three essential components, often called the “Three Pillars” of optical communication: Laser — generates light. Modulator — encodes data onto the light. It generally has the components for transmission, reception, laser chips, photodetctor chip. In the era of 5G, AI, and high-speed data centers, optical modules serve as the core bridge for converting electrical signals to optical signals (and vice versa), enabling fast, reliable data transmission across networks. Today we will learn and explore the working principle of the optical transceiver. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside. Modern communication networks rely on optical transceivers to transfer data at the speed of light.
