FTTx stands for fibre to the x, which is described as various topologies from where optical fibres are delivered to customers based on its termination point. Earlier metal cables were used for covering long distances but now, FTTx cables have been deployed to replace them. Fibre to the premise (FTTP) and Fibre to the cabinet (FTTC) are the two main groups of architecture. In FTTP, the optical cable runs through distribution network to a subscriber’s premise, in a building or an office. In FTTC, the optical cable runs through a central node.
