A new kind of fiber optic data bus (fiber tree bus, FTB) is presented, mainly aiming at some defects of available standard bus, which is lack of real-time performance, has no information interactive transmission index, and uncontrollable transmission delay when it is applied in high bandwidth, distributed real-time information transmission and interactive conditions. The internal working mode, tree topology and Transfer protocol of FTB are designed. The main technical characteristics and real-time transmission performance of FTB are introduced in details. A photoelectric information transmission system has been established based on FTB, to meet the application requirements of the military vehicle-borne photoelectric system. It can access and transmit a variety of communication data at the same time, such as Gigabit Network, CAN, RS232, RS485, RS422, SDI, etc. The compared results of analysis and test show that the new bus system is capable of transferring a various types of real-time information. The characteristics and advantages of FTB application are summarized finally. |
