Airborne unified network based on time trigger is an important development direction of next generation aviation airborne system technology.In order to achieve the rapid and reliable interconnection of network equipment, it needs to establish a network protocol standard and test the consistency test of the agreement to ensure that the network signal is reliable and the protocol is correct and trouble-free. Based on the AS6802 and IEEE 802.3 protocols and the requirements of airborne network, this paper selects the standards applicable to the physical layer and link layer of airborne time-triggered network, and establishes the airborne unified network equipment standard. According to the network standard design test project, in conjunction with the test needs, the FPGA(Field Programmable Gate Array)-based testing environment is established. The optical oscilloscope, optical power meter, optical attenuator and other devices are used to test the physical layer signal characteristics such as the sending end eye map, signal rate, rise and fall time, extinction ratio, average optical power, bit error rate at the receiving end, and receiving sensitivity. The network frame required for the test is sent by the specific device simulation end system, and the consistency test of link layer protocol state machine and synchronization parameters is carried out. The test results show that the bit error ratio of network devices is less than 10-12, and indicators such as eye maps meet the physical layer standards. The state machine jump meets the link layer protocol. Important synchronization parameters meet the requirements. Manufacturers achieved interconnection.
