Аннотация:The article provides the experimental model of TWDM-PON. Method. A large number of papers, especially from international platforms IEEE and OFC, have been studied, as the result of this knowledge was built the model of TWDM-PON. For the creation of this model was used VPIphotonicsTM simulation software. Core results. During the deep study of NG-PON2 was de- scribed the main options of TWDM-PON, and characterized the principal components to build this model. Based on this knowledge was created the simulation of downstream transmission in TWDM- PON. Practical relevance. The resulting model provides the opportunity to test in real time the TWDM-PON. For example, by changing the distance or some other parameters while controlling the received power and bit error rate.
