In order to study multiplexers,the design and implementation of coalition of multi-route data and voice based on free space optical communication (FSO) was introduced.Combining FSO technical advantages with telephone line transmission system,the compound interface between digital signal and voice was implemented based on field programmable gate array (FPGA). The FPGA was programmed with Verilog hardware description language (HDL),and the whole trajectory was simulated with QUARTUSⅡsoftware.As a result,the channel efficiency was promoted and the transfer capacity was increased because of the capability of digital multiple connection.The results show that the system is able to transfer 30-channel audio signal.
