The invention relates to the FTTH installation of fiber optic cables in a building (9) to create a fiber optic connection between a fiber optic termination unit (4) at a building entry point (BEP) and at least one fiber optic termination unit (2) designed as a fiber optic terminal adapter in the form of an optical network termination box (OTO), wherein the fiber optic connection is optionally routed via a further fiber optic termination unit (3, 3') designed as a hallway box (FB). The fiber optic cable length required between a fiber optic termination unit (2, 3, 3') to be arranged at an installation location and the fiber optic termination unit (3, 3', 4) nearest to the BEP (1) is determined as the installation distance.At the installation site, a fiber optic termination point (2, 3, 3') is provided, supplied with a coiled length (7) of fiber optic cable (5) exceeding the installation distance. The fiber optic cable (5) is equipped with at least one fiber optic connector (6) at each end. Fiber optic cable (5) of a length corresponding to the installation distance is unwound from the coil (7), and the at least one fiber optic connector (6) is connected to a fiber optic connector of the next fiber optic termination point (3, 3', 4). These steps are repeated as necessary until a fiber optic connection exists between the OTO and the BEP (1).

Techniques for augmenting repair of a network failure in a Passive Optical Network (PON) include receiving sensor data at a client device indicating a current environment that includes an optical network terminal (ONT) in a PON. The PON includes an optical line terminal (OLT) optically connected to the ONT via one or more optical fibers. The client device analyzes the current environment to detect a cause of a network failure corresponding to the ONT, and generates a set of instructions for repairing the ONT based on the detected cause of the network failure. Then the client device provides the set of instructions for a user to follow to repair the ONT. The set of instructions are provided as the user repairs the ONT.
