Passive optical network-based video overlay pluggable type optical network device

A passive optical network (PON)-based video overlay pluggable type optical network device comprising:

• a triplexer optical sub-assembly including:
• an optical cable connector connected to an optical splitter;
• a first connector connected to a passive optical network processing unit;
• and a second connector connected to a video radio frequency processing unit, wherein when a detachable optical cable is inserted into the optical cable connector, the triplexer optical sub-assembly is connected to the optical splitter and receives a video overlay optical signal, separates a PON optical signal and an RF optical signal from the received video overlay optical signal and outputs the resulting PON optical signal through the first connector, outputs the resulting RF optical signal through the second connector, and transmits the PON optical signal input through the first connector to the optical splitter through the optical cable connector;
• an RF board, on which the video radio frequency processing unit is provided, including:
• a second connector connected to the second connector of the triplexer optical sub-assembly;
• and a third connector connected to the passive optical network processing unit, wherein an RF signal subjected to photoelectric conversion, which is input through the second connector of the RF board, is amplified by the video radio frequency processing unit and is output through the third connector, and the RF board is controlled by the passive optical network processing unit via the third connector;
• a PON board, on which the passive optical network processing unit is provided, including:
• a first connector connected to the first connector of the triplexer optical sub-assembly;
• a third connector connected to the third connector of the video radio frequency processing unit;
• and an optical network terminal (ONT) connector provided to be inserted and removed from an ONT, wherein the PON board transmits and receives the PON optical signal through the first connector of the triplexer optical sub-assembly, and is connected to the third connector of the RF board through the third connector of the PON board to receive the RF signal and to transmit a control signal, and the ONT connector transmits a PON signal and the RF signal to the ONT and receives the PON signal when being inserted into the ONT;
• and
• an electromagnetic wave shielding part provided between the RF board and the PON board and at an upper portion and a lower portion, the electromagnetic wave shielding part blocking interference between the RF signal and the PON signal and blocking electromagnetic waves from emission to outside.
