Fiber Optic Bus for Space Applications

摘要

In order to meet the stringent spacecraft performances and associated complex requirements, need for lightweight and high capacity communication system as its internal bus for command and control are increasing. The advantages of fiber optic bus system over the conventional electrical bus system make it a suitable candidate for the above requirements. Activity carriedout elsewhere in this regard is reviewed here with an aim to develop a fiber optic system, which could be used in future spacecrafts of ISRO. There are advantages and at the same time there are disadvantages in using this fiber optic bus. A proper hardness assurance program at the component level, careful electrical, optical and opt electrical designs and well thought out system protocol are essential to develop a qualified fiber optic link for space application.
