Who will pay for the broken network cable of commercial housing?

The optical fiber at home is broken, and the property is responsible for maintenance. The maintenance responsibility of all operators is to interface to the LAN port of fttp or the optical cat entering the building. As long as the Ethernet port test of the optical cat is normal, it means that the operator's network is normal. If there is something wrong with the comprehensive wiring of the building, you can find a property management company to repair it. These network cables were laid during the construction of the building and have nothing to do with the operators.
