Abstract:

A high-speed data acquisition system is designed based on an optical fiber communication network.By way of multi-channel data acquisition,and combined with fiber-optic communications network,the high-speed data acquisition capability has been greatly improved.The system consists of the processing systems,fiber optic networks and the collection module.Signals collected by the front-end optical fiber communication network are processed by analog filter and sampling and then transmitted by the processor.Experiments on the optical data acquisition system prove that the application of fiber-optic communication networks in high speed data acquisition system can achieve optical data access rates less than 10 Gbit·s-1.

Key words: high number of data acquisition systems;optical fiber communication network;acquisition mode
