The utility model discloses a multipath-fiber-to-parallel LVDS data communication adapter card which includes an FPGA which contains a BRAM inside, a voltage stabilizing chip, a first fiber interface, a second fiber interface, a first photoelectric conversion module, a second photoelectric conversion module, a PCI bridging chip, a first SDRAM, a second SDRAM, a third SDRAM and a forth SDARM. The first fiber interface is connected with the FPGA through the first photoelectric conversion module. The second fiber interface is connected with the FPGA through the second photoelectric conversion module. All of the first SDRAM, the second SDRAM, the third SDRAM and the forth SDARM are connected with the FPGA. The FPGA is externally connected with a main control computer through the PCI bridging chip. The voltage stabilizing chip is connected with an external power supply and supplies power to the parts. The multipath-fiber-to-parallel LVDS data communication adapter card overcomes defects of the prior three kinds of
