Which connector is used to connect the router to the fiber optic cable

Fiber optic cables typically connect to a router via an SFP or WAN port designed for fiber input, often using LC or SC connectors.How Fiber Connects to a RouterMost standard home routers do not accept fiber optic cables directly because the optical signal must first be converted into an electrical signal. This conversion is handled by an Optical Network Terminal (ONT), which is usually provided by your Internet Service Provider (ISP) and installed near the fiber entry point in your home or office . The fiber cable plugs into the ONT's optical port, which then outputs data through a standard Ethernet port to your router .Router Ports for FiberRouters that support fiber connections typically have:SFP (Small Form-Factor Pluggable) ports: These ports accept fiber modules that convert optical signals to electrical signals compatible with the router. SFP ports are hot-swappable and can support single-mode or multi-mode fiber depending on the module .WAN ports labeled "Fiber" or "ONT": Some fiber-ready routers have dedicated WAN ports for connecting to the ONT via Ethernet after the optical signal is converted .Common Fiber ConnectorsThe physical connectors used for fiber connections include:LC connector: Small, commonly used with SFP modules on routers, easy to operate with a latch mechanism .SC connector: Larger, often used in optical distribution frames or ONTs .ST connector: Rectangular plug-in type, sometimes used on router switches .SummaryTo connect a fiber optic cable to a router:Fiber cable → ONT: The fiber cable plugs into the ONT's optical port.ONT → Router: Use an Ethernet cable from the ONT's LAN port to the router's WAN port, or insert an SFP module into the router's SFP port and connect the fiber directly if supported.Router configuration: Access the router's admin panel to configure the connection as needed . In short, the fiber optic interface on a router is usually an SFP port or a WAN port designed for fiber input, and the actual fiber cable often terminates at an ONT before reaching the router.
