Distance from fiber optic cable to router

The fiber optic cable should ideally run within 3 meters of the ISP's entry point to the ONT, and the ONT can then connect to the router via an Ethernet cable up to 100 meters.Fiber Optic Cable to ONTFiber optic cables transmit data via light, and their performance can degrade if the cable is excessively long or bent sharply. For residential installations, it is recommended to position the ONT within 3 meters of the fiber entry point to minimize signal loss and maintain optimal speeds . Fiber cables are delicate and cannot tolerate 90-degree bends; the minimum bend radius is typically around 30 mm, so routing around skirting boards or door frames should be done carefully . Improper connections or tight bends can reduce signal strength by over 30% .ONT to Router ConnectionOnce the fiber reaches the ONT, it is converted into an electrical signal that the router can use. The ONT is then connected to the router using a standard Ethernet cable (Cat5e, Cat6, or higher). Ethernet cables can theoretically run up to 100 meters without significant signal degradation, allowing flexibility in router placement within the home . For higher speeds or future-proofing, Cat6a or Cat7 cables are recommended, especially if the router supports gigabit or multi-gigabit connections .Practical Installation TipsONT Placement: Place the ONT near a power outlet and within a short distance from the fiber entry point to reduce signal loss .Cable Routing: Avoid sharp bends and maintain the minimum bend radius. Use gentle curves around corners and door frames .Router Connection: Use a high-quality Ethernet cable to connect the ONT to the router. The cable can be longer than the fiber itself, up to 100 meters, without affecting performance .Flexibility: Fiber cables are flexible but should not be twisted or pinched. Ethernet cables provide more flexibility for routing to the router location. By following these guidelines, you can ensure a reliable fiber-to-router connection with minimal signal loss and optimal network performance.
