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