Explanation

An Optical Network Terminal (ONT) is the device installed at a customer's premises that converts fiber-optic light signals from the ISP's fiber network into electrical (Ethernet) signals that a router can use. This is standard in FTTH (Fiber to the Home) deployments. A Hub (A) connects multiple Ethernet devices. PoE (B) provides power over Ethernet cables. A NIC (D) is a network interface card inside a device - none of these perform optical-to-electrical signal conversion.
