FTTH Architecture PON versus P2P Ethernet
In this page, we only describes the passive infrastructure, it will not go into any depth on architecture.
Basically there are two options in architecture that are important for the choice of passive infrastructure.
The drawings below show the PON and P2P Ethernet options schematically. The difference in the two options is mainly the number of fibres in the feeder cable.
PON Architecture
Ethernet P2P Architecture
The PON architecture is based on one single optical driver for up to 64 users (in the future 128 users.) Passive splitters divide the signal somewhere in the network to the different users. The splitters can be placed in the Access Node or in one of the distribution points.
The P2P Ethernet Architecture has one optical port for every user thus creating a dedicated fibre connection from the Point of Presence (POP) to each individual user.
If the passive infrastructure needs to be able to handle both architectures it is necessary to calculate the highest fibre count in the feeder.
