  • The differences between Free Space Optical(FSO) communication and traditional communications are investigated, and a physical layer transceiving protocol is built. A field Programmable Gate Array(FPGA) is introduced to achieve the data communication of both the transceiver and outer circuits, and a First in First out(FIFO) memory is utilized to implement the interface of protocol and outer systems. The protocol mainly achieves coding and serializing of the transmitting data and deserializing and decoding of the received data. The result of simulation experiment proves that the transceiving protocol is feasible, which can work reliably at a speed of 40 Mbps.
