Description

technical field [0001] The invention relates to data transmission, in particular to an ultra-high-speed data transmission system and method based on a high-speed optical fiber Ethernet network. Background technique [0002] Maskless lithography equipment is a kind of equipment that uses multiple optical engines to work at the same time. It needs to transmit a large amount of data in real time from the main control workstation to each optical engine. The real-time performance and accuracy of data transmission will affect the quality of the entire lithography equipment. Work efficiency and stability. [0003] Existing data transmission systems mostly use Gigabit Ethernet or dedicated optical fiber to communicate with the host / slave through a single optical engine. This method has the following problems: [0004] 1) There is an independent data link between each optical engine and the host computer, resulting in a large number of lines between the host computer and the exposur...
