Gigabit Passive Optical Networks is a fiber optic technology (GPON Technology) that allows a higher speed of transmission and reception of data through a single fiber. With a point-to-multipoint architecture, it will enable optical fiber to the home, or a building. It allows access to Video, Voice, and Data and arose with the need to enhance copper networks. Now, copper and state-of-the-art fiber optic offer solutions adapted to each need.
A GPON network is capable of transmitting multiplexing divided by time (TDM), Ethernet, and ATP traffic. These type of networks consists of an OLT (Optical Line Terminals) unit, an ONU (Optical Network Unit) and a splitter (Splitter). The splitter will redirect the signal when necessary. The OLT unit takes all the optical signals in the form of light beams from the ONUs and converts them into electrical signals. OLTs typically support up to 72 ports. An ONU connects end users and forwards the signal back to the OLTs. A GPON Network supports a physical distance of up to 20 kilometers and can provide service to 64 end users. GPON uses upstream and downstream data using Optical Wavelength Division Multiplexing (WDM).
