摘要： 针对回接已有设施开发而预留光纤芯数资源受限的水下油气田，提出一种基于环形拓扑的水下生产系统光纤通信系统，此方案基于环形拓扑对于光纤资源高效的利用率及拓扑结构优越的拓展性，单个环路仅需采用4芯光纤，可以有效地解决光纤资源受限的问题，且系统具有优越的拓展功能。然后针对系统开展方案设计，并给出了通信校核的标准、校核方法及实际应用案例。最后基于水下生产系统不同项目的特点分析了星形拓扑和环形拓扑的适用性，为水下生产系统的通信方案设计提供了参考。

Abstract: An optical fiber communication system based on ring topology is proposed for the development of subsea oil and gas fields reconnecting to the existing facilities with limited resources reserved fiber cores， which is based on the efficient utilization rate of optical fiber resources and the superior scalability of topology based on ring topology， and only 4-core fibers are needed for a single loop， which can effectively solve the problem of limited optical fiber resources， and the system has superior expansion ability. Then， the scheme design of the system is carried out， and the standards and methods of the communication verification and practical application case are given， Finally， based on the characteristics of different projects of the subsea production system， the applicability of the star topology and the ring topology is analyzed， which provides a reference for the communication scheme design of the subsea production system.

Key words: subsea production control system, optic fiber communication, ring topology, system design
