In the field of optical communication, the packaging of optical devices plays a crucial role in the performance and application of optical modules. Optical modules are key transmission components in communication networks, and their applications, technologies, types, and terminology are diverse. When discussing optical modules, what are we actually talking about? This article aims to delve into. The optical transceiver module has three major components, which are opto-electronic devices (TOSA/ROSA), a circuit board with electronic components (PCBA) and optical interfaces (housings) such as LC, SC and MPO. Figure1: Components of an Optical Transceiver The optical transmitting part is. The invention relates to the technical field of optical packaging, and particularly discloses a CPO optical module packaging structure and a wafer level packaging method thereof, wherein the CPO optical module packaging structure comprises the following components: providing an electric chip. The difference between hermetic and non-hermetic packaging of optical modules mainly lies in the packaging method applied in optical chip packaging—specifically, whether the light-emitting semiconductor chips and optical detectors are installed in a sealed cavity.
