Since the optical fibers of multiple cores are laid in a bundled cable state, a certain level of strength is secured, and since the optical fiber is laid in a place that is difficult for the general public to touch, the optical fibers in that cable are disconnected. Things are rare. However, since a single-core optical fiber is drawn from the relay point to the user's house, the strength is lower than that between the station and the relay point, and it is laid in a place where ordinary people can easily touch. It can be said that a single-core optical fiber is in a state where a communication failure such as a disconnection is likely to occur. If a communication failure occurs in such a single-core optical fiber, the corresponding user will not be able to communicate, and in particular, if communication equipment such as a telephone becomes unavailable, it will be impossible to communicate with the outside. There are challenges.
