FTTH indoor solution for GPON offers a way to quickly and easily build an optical infrastructure in buildings of varying sizes. The primary cable is spliced into the main MTeH UNI distribution box, where it is terminated or passes through. One fibre of the incoming cable is terminated per each 8 apartments by splicing to the SC/APC pigtail. These are the only splices made in the building. One patchcord is conducted from the main distribution box to connect the floor distribution box, in which a pre-connectorized splitter with a split ratio of 1:8 is installed. If there are multiple floor distribution boxes, each of them is connected by its own patchcord. An ORM 1 socket is always installed at the client's end, connected by its own patchcord to the floor distribution box. The indoor infrastructure is therefore completely free of optical splicing. For MDUs with less than eight apartments, the splitter is installed as far as the distribution point of the network. That is the design of the indoor end of the solution; the split ratios in the network may be modified according to the customer's needs.
