The GPON Doctor™ 9500 are always provided with an external splitter. This splitter has
the following interfaces:

OLT interface. Green Plug (for APC endfaces). This is where the fibre connection
from the OLT should be plugged.

ONT interface. Green Plug (for APC endfaces). This is where the fibre connection
to the ONTs should be plugged.

Down interface. Green Plug (for APC endfaces). This interface must be connected
to the GPON Doctor™ 9500 DOWN Stream (UPC) interface.

Up interface. Green Plug (for APC endfaces). This interface must be connected to
the GPON Doctor™ 9500 UP Stream (UPC) interface.

1. Introduces attenuation
The presence of splitters in the PON attenuates the optical signal and reduces the power
budget. To all intents and purposes, the architecture between the OLT and an ONT could
be simplified as a fibre with an attenuator in the middle. The value of this attenuator
depends on the number of splitting levels within the PON.
Connecting the GPON Doctor™ 9500 external splitter to the PON will add 7dB of
attenuation. Therefore, before placing the splitter into the network, it must be checked
that there is enough margin so that the normal operation is not impacted.
