The FTTH terminal box is a device used in the Fiber to the Home network system. It is usually installed inside the home or in the corridor, and serves as the interface point of the fiber optical cable. In the construction of FTTH network, the fiber optical cable is connected to the FTTH terminal box through fusion splicing or plugging, and further connected to terminal equipment such as fiber optical PLC splitter or optical transceiver module through fiber optical jumper wires.
