The critical dependency lies in how passive optical components age through cumulative physical and material processes rather than discrete failure events. Table 2 summarizes some typical failure modes. Failure mechanisms of electronic semiconductor devices can be divided into the following general categories: (1) Material-interaction-induced mechanisms. (3) Mechanically induced failure mechanisms. Material-induced. Pspice is used to simulate the electrical stress, Calce FAST mainly resolve life prediction problems correlating electro-mechanism individually, and MATLAB is utilized to fit the degradation curves according to enough data which have been obtained above. Finally, a system failure mechanism tree. Passive optical components are often assumed to be static elements in a network—once installed, they are expected to behave consistently for years with minimal attention.
