| Abstract: | One cost efficient fiber optical muldex (FOM) system to transmit small or middle business as the transition of optical access production was put forward and designed. It is implemented by one step multiplexing 2 to 16E1 on FPGA. The core functions of the system were designed by top down flow in VHDL, on the ground of defining the system frame in reason. The simulation and testing of the system including the multiplexing and demultiplexing functions were accomplished on 25 million gate FPGA. The realizability of this project has been proved. |
