Forward and backward Raman scattering photon counts in a FTTH topology.

This set comprises a simulation tool in Mathematica for the generated Raman noise in a GPON-based FTTH topology. This set takes into consideration various FTTH parameters, such as the number of Optical Network Terminals (ONTs) and the splitting ratios, as well as the drop and feeder fiber lengths, as it is depicted in Figure 1, providing in the output the expected Raman noise counts calculated in counts per second (cps) detected in a Single Photon Detector (SPD). The user of the code can manipulate various setup parameters, such as the filtering passband and loss, as well as the specific SPAD parameters which can be selected to be operating either in gated or free running mode. The code provides as an output the expected noise count rates (cps) associated with the forward and backward Raman scattering effect.
