In FTTX, the 'X' represents the place where network finally terminates at, such as a curb, a home, an office or a cabinet. So FTTX could be Fibre to the Curb, Fibre to the Home (FTTH), (FTTC), Fibre to the Office (FTTO), Fiber to the Terminal (FTTT). In fiber to the X (FTTX) network, the fibers are closer to end-users, thus to offer a low-latency, high-bandwidth and fast-speed fibre network, which can meet the requirements of 5G development.
