OPTICAL LINE TERMINATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an optical line termination device capable of detecting the disconnection of power due to poor connection.SOLUTION: An optical line termination device comprises: a connector including a first connection terminal and a second connection terminal shorter in length in an insertion direction than the first connection terminal, the connection terminals being inserted into a port in a node device; a power supply unit for receiving power from the power line of the node device via the first connection terminal; and a detection unit that detects the disconnection of power by obtaining the voltage value of power from the supply line of the node device via the second connection terminal, and outputs a control signal indicating that the power is disconnected.SELECTED DRAWING: Figure 1
