Figure 7 Impact of the splitter within the PON
If the optical power budget is not enough, the GPON Doctor™ will need to be connected
to the PON by means of already placed splitters (like in figure 5). The impact on the
network is caused by the splitters installed by the customer. 50/50 splitters reduce the
optical signal by 7dB.
In this case, to assure an optimal behaviour, it must be checked that the optical power
available to the GPON Doctor™ is higher than -28.5dBm in Upstream and -28.5dBm in
Downstream. Furthermore, a lower power level below ‘sensitivity’ or a higher power level
over ‘saturation/overload’ results in failure to capture the data correctly. Higher power
level can be adjusted to acceptable values by means of attenuators.
