The FTTH (Fiber-To-The-Home) networks are 100% optic and are responsible for taking the optic fiber into the customer's house, which are individual constructions and non-vertical (apartments), just like offices, houses and housing associations.
The PON (Passive Optical Network) used in FTTH (Fiber-To-The-Home) architectures for the provision of data, voice and video services basically use the division of optical fibers coming from the OLT ports at the central office of the service provider until they reach the homes of subscribers. As it is a transparent network free from active equipment between points, it may be used by different technologies like GPON and EPON.
This is the start of the network where the optical transmission equipment (OLTs), Optical Distributors, splitters, racks and cords are installed.
Responsible for the transition of the cables of greater amount of optic fiber which come from the central, to the smaller amount of optic fiber which are going to arrive in the customer’s boxes. The key products central office for this application are the splice boxes (CEO) and the splitters.
Transition between the cables from distribution network external to internal. The key products for this application are the termination boxes (CTO) and the access cables, as an example the Drop Cables.
At the end of the network happens the transition from the drop cables to the connection of the termination equipment (ONU/ONT), passing through the termination point (PTO/Rossette). In this termination point, the ONU/ONT is interconnected to the access network through an optic cord.
