The MBI fiber-based data transmission system
The MBI fiber-based data transmission system is the bridge of payload and data processing systems (or data-transmission systems, mission systems). MBI in the load side plate and electric control, data output closely, load the data through the multiplexer and switch to string, 8B/10B encoding, electro-optical conversion after the high-speed data transmission through optical fibers, while the control instructions issued by the bus load by 1553B electronic control system; end in data processing systems, MBI board receives load data, and send control commands. MBI,. MBI data transmission system standardized payload data transmission standards, suitable for multi-task system load of data transfer and load control.
Features
1, high reliability through rigorous environmental testing and screening test, with reliable electrical and mechanical properties for aerospace applications;
2, high-speed data transmission to support high-speed Fiber Channel data bus (one-way transfer rate of 2.0Gbps, support multi-way parallel), while supporting low-speed 1553B bus;
3, load control and data integration system will be integrated load control and data transmission through the MBI control panel payload and receive payload data;
4, the bit error rate is low before the use of 8B/10B encoded data and make CRC check, the system has a lower bit error rate;
5, electromagnetic compatibility, good high-speed data transmission technology, electromagnetic compatibility is a major bottleneck, but this system will use high-speed part of the optical fiber transmission, to ensure that the system has good electromagnetic compatibility.
