Abstract:

This paper takes the test interconnection system of the civil avionics system as an example to introduce a design technique of the test interconnection network. In the process of large and complex electronic system development, it is always a necessary step to implement interconnection project among distributed test facility to meet transmission quality and delay requirement of the test signals. The extensible test interconnection network showed in this paper adopts multi electrical signal adaptation technology based on optical fiber network, and the network is constructed by the core equipment: fiber switch and signal conversion device. Finally the test analysis of the prototype system shows that in the case of ensuring the quality of the signal, the transmission delay is no more than 60μs.
