FPGA-based hundred-megabit optical physical layer and device thereof

The invention provides an FPGA (Field Programmable Gate Array)-based megabit optical physical layer and a device thereof. The physical layer comprises a physical coding sub-layer and a physical medium attachment sub-layer. The physical coding sub-layer comprises a bit width encoder, a parallel-serial conversion module, a serial-parallel conversion module, a bit width decoder and a carrier detection module, the bit width encoder is coupled to the medium independent interface and the parallel-serial conversion module, the bit width decoder is coupled to the medium independent interface and the serial-parallel conversion module. The carrier detection module is coupled to the media independent interface, the bit width encoder and the bit width decoder. The physical medium attachment sub-layer comprises a non-return-to-zero and reverse encoder, a non-return-to-zero and reverse decoder, a connection controller, a data recovery module and a carrier detection module, the non-return-to-zero and reverse encoder is coup
