What should be done if fiber optic cables are installed in the home through cable trays
Use fiber patch panels, cable management trays, and routing guides to prevent excessive bending, stress, or accidental disconnections. Additionally, maintain proper separation between fiber optic and power cables to support safe installation practices and long-term system. You are suggested to use some tools for easy fiber optic cable management, like trays, J-hooks and cable ties. Fiber optic cables inside rack cabinets should be neatly organized to ensure efficient management and long-term reliability. Outdoor cable may be direct buried, pulled or blown into conduit or innerduct, or installed aerially between poles. You can eliminate 95%. They are installed in the same general location by the same people for the same general purpose.
