This final phase is centred on the connection of the PON network to the optical splitting
module at the measurement point. This process is carried out by connecting the fibre from
the OLT to the “OLT optical splitter port” and the fibre directed to the ONTs to the “ONT
optical splitter port”.
2.3 Connection to one End of the PON Network
Figure 10 shows a scenario where the GPON Doctor™ analyzer is connected at one end of
a PON network. In this configuration, the analyzer can capture all downstream traffic
generated by the OLT but only the upstream traffic generated by the ONT connected
behind it.
Figure 10 Connection to one End of the PON Network.
Connecting the GPON Doctor™ to one end of a PON involves the following stages:

Upstream/Downstream signal reception power measurement/inference at the
target capture point.

Calculation of the attenuation required for the capture card inputs.

Addition of the necessary attenuators (if needed).

Connection of the optical splitter to the fibres.
Optical power budget measurement
The objective of this first step is to calculate the optical power level at the PON inputs of
the external optical splitter. This process is specific to each direction of the
communication.

Power in Downstream direction: The value is obtained by using a PON power
meter or by inferring the theoretical attenuation up to the physical capture point.
