Communication optical cable network transmission ring and same-trench same-cable identification drawing method

A communication optical cable network transmission ring and same-trench same-cable identifier drawing method comprises the following steps: calling service to obtain complete routing data, and classifying the routing data; defining an initial configuration variable of topology calculation; according to an initial configuration variable for defining topological calculation, performing topological coordinate calculation construction on different types of routing data to obtain constructed topological data; and according to the obtained constructed topological data, drawing a topological graph, and according to the drawn topological graph, drawing a same-trench and same-cable analysis result identifier. According to the invention, various types of routing data are supported; according to the topological graph drawn by the method, the symmetry and the attractiveness are ensured; according to the method, the same-trench and same-cable identification is overlapped on the topological graph for drawing and display, a
