CHAPTER 8. PHYSICAL SETUP
8. Physical Setup
8.1 Overview
To achieve any GPON setup described in this manual it is assumed that there is
an OLT, which configures the ONU. According to ITU-T G.984.1[3] it is intended
to have a passive fiber connection between the OLT and the ONU. It may include
optical splitters as well as other passive network components. In a typical FTTH
scenario the ONU is connected to the OLT via the ODN and the customer
may connect it to his local network. The OLT must also be connected to the
service providers’ network. The setup may vary for different scenarios. For an
introduction into GPON please refer to the chapter Introduction into GPON.
Additionally refer to the manual of the OLT vendor to be sure the ONU is
connected correctly.
8.2 IP Multiservice Access Platform (IPSAN)
In case of using the IPSAN as OLT, there is a dedicated GPON card installed
which is used to connect the ONU via the ODN to a GPON interface at the
GPON card of the IPSAN. Such a GPON interface is also called ponlink in
short which will be the convention in this document. In addition to the ONU
connections, the IPSAN needs at least one more connection, which acts as uplink
to the service providers’ network. Depending on the customers needs, it is also
possible to define more than one uplink. Each of the connections to the IPSAN
may need a specific SFP to connect the cables to the interfaces. The setup for
the scenario with FTTH described above remains the same. Note that the IPSAN
is not only an OLT and may be used for other purposes too. For a full guide to
all of the supported GPON features, as well as other functionalities please refer
to the dedicated IPSAN’s User Manual.[1]
