A FPGA Implementation Method of Data Transmission through Optical Fiber Bus for Wire-Guided Torpedo

According to the characteristics of optical fiber data transmission, this paper proposes a data transmission method through the optical fiber bus of a wire-guided torpedo based on field-programmable gate array(FPGA).The method combines the custom framing format with the 8B/10B coding and decoding, and can be achieved only by a single FPGA. It simplifies the system structure, and has the advantages such as simple composition, small transmission delay and high transmission reliability. Simulation result shows that the bit error rate is less than 10-6 as the effective optical fiber transmission rate is 100 Mb/s. This method can realize reliable data transmission through Ethernet bus for optical fiber wire-guided communication.
