In order to meet the requirements of aerospace ground support systems, a platform-based design scheme for optical fiber packet transport modules is proposed. This scheme adopts a unified bearer approach based on packet switching, reuses VITA Standard 46（VPX） hardware interfaces, and extends the compatibility of standard communication protocols. Through modular software and hardware design, the scheme implements functions such as module type identification, inter-board communication, and configuration/status management. Application results show that this scheme avoids redundant development of common technologies, effectively reduces system complexity, and accelerates product development and iteration.
