CONVERTER BOXES

Set of ITU-T G.984.x recommendations where the techniques for sharing a common medium (FO) by several users, encapsulating information and managing network elements, among other aspects, are described.

The scheme of a GPON network is made up of three fundamental parts: the OLT, ODN and ONT. The OLT is located in the service provider’s node and contains all the active equipment. The ODN (Optical Distribution Network) is the passive optical distribution network that includes the feeder network, the distribution network and the dispersion network, where its most important element is the splitter in charge of dividing the signals to the respective ONTs of the users. The NAP (Network Access Point), commonly called optical distribution box, is the terminal equipment that connects the distribution network with the dispersion network. Finally, the ONT is located in the customer’s home, which is the terminal equipment of the GPON network, which receives the optical signals and transforms them into electrical signals.

The active devices of the basic network are:

• OLT. Optical Line Terminal. center team.
• ONT/ONU. Optical Network Termination (Unit). user equipment.
