PON and GPON networks The acronym PON, frequently used in fiber installations, comes from English. It stands for Passive Optical Network. It is a passive network, with a single point of transmission to different user points. A PON network has no more active elements to reactivate the signal. The distribution is carried out by means of optical distributors or splitters. It is the topology used in FTTH installations (fiber to the home). When the transmission speed is capable of ensuring 2.4Gbit/s at a distance of 20 km and 128 users, we say that we are dealing with a GPON network. And this is what, normally, we have in our homes.
