First I made a TDM-PON network based on G-PON technology that simulates normally after I made a TWDM-PON network based on this palette that uses the G-PON technology, made using an IEEE article, putting a WC (splitter/combiner) that is inserted into the central Office (CO) and the remote node (RN) in advance that is to upgrade without substantially change the structure of the network already installed : employed a three-port device that combines/separates wavelength band. The range of wavelength used in the downstream and upstream are 1260 ~ 1360nm and ~ 1480 ~ 1500nm, respectively. On the network already installed, the splitter connects 8 ONUs using wavelength λ1. For upgrading, entered in the OLT optical source generating 16 new wavelengths, that through the WC1 integrate to λ1 and are released in the fiber. In RN, the WC2 separates the new wavelengths and sends them to the gateway of the AWG, while the λ1 continues connecting to optical passive splitter. In this way, it would have an increase in the number of users taking advantage as much as possible of the structure already installed. If the user wishes to make use of current services (hitherto provided by the divisor) and also the new generation services will then be necessary to add more 2 WCs, one in RN and others in the ONU itself. I did exactly that I put on the existing toilet, ONUs so that the simulation of error? What is causing the error?
