In a fiber-optic network, there are devices that are necessary to complete the fiber to the home (FTTH) link. It connects directly to the optical line terminal (OLT) at the central office and serves as the endpoint for fiber-optic signals in the user's premises. In fiber-optic networking—especially in Passive Optical Networks (PON)—terms like ONT (Optical Network Terminal) and ONU (Optical Network Unit) are often used interchangeably.

It is the optical terminal device in the fiber access network, which provides users with multiple service interfaces. Therefore, ONU can transmit optical signals into electrical signals and vice versa. SFU (Subscriber-Facing Unit): designed for individual users, providing basic connectivity for a single home or office in fiber-optic networks. Connectivity Needs: Opt for models with VoIP support or other specific features, such as Wi-Fi or PoE.

It connects to a passive optical splitter that multiplies and relays the signal to other fiber strands through optical distribution waveguide technology. Unlike active devices (which require power), splitters operate without electricity, relying solely on the physics of. As more network backbones are built on fiber, new opportunities involving passive optical local area networks (POLAN) emerge. PLC splitters are based on planar lightwave circuit technology, ensuring uniform signal distribution and supporting high split ratios up to 1×64 or even higher.
