Abstract


Passive optical networks are the most promising solution for access networks. The first standard provided only 155 Mbit/s but current networks work according to ITU-T G.984.3 with 2.5 Gbit/s in downstream. However, NG-PON2 offers up to 40 Gbit/s in downstream by 4 different wavelengths. This article deals with an implementation of transmission convergence layer in VPIphotonics. This tool is dedicated only for simulations of physical layer. The main aim is to present a simulation of physical layer for NG-PON2 in comparison with our implementation of transmission convergence layer and encapsulated frames according to ITU-T G.989.3. Our results confirm expanding the entire system reach with the real encapsulation method of 3 sublayers model and error correction mechanism. The 3 sublayers model can be easily extended to all passive optical networks simulations in VPIphotonics simulation tool.
