Based on Huawei's all-optical network system and the signal platform advantages of E-Hualu, E-Hualu upgraded the MT1032-96X signal machine to adapt to the all-optical intersection iteratively, and created a new type of signal machine - all-optical signal machine (distributed signal machine DT2201). It transformed the traditional centralized signal control into a distributed architecture. It used an optical bus architecture to replace nearly 100 signal control lines at the traditional intersection with an optical composite cable, and transmitted the intersection light control information through optical fiber to achieve highly reliable intersection signal control.
