Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a multi-type information transmission device adapted to an optical fiber network. Background technique [0002] In the data transmission process based on the optical fiber network, the data of each test device needs to be transmitted through the optical fiber network. Because this process involves many types of test equipment, such as analog, switch, RS422 serial data and LVDS bus. If each test equipment is directly connected to the optical fiber network, the following problems exist: [0003] (1) It is necessary to design a corresponding number of optical fiber buses; [0004] (2) It is necessary to ensure that the optical fiber bus is compatible with the hardware interface of each test equipment; [0005] (3) The specific conditions of each test equipment need to be considered; [0006] (4) In the existing method, the test equipment starts to collect and transmit ...
