| 摘要 |
The present invention relates to an optical transmission device for transmitting a broadcast signal through an optical subscriber network, comprising an electrophotic conversion module which converts an RF broadcast signal received through an RF broadcast signal reception terminal to an optical signal to be outputted; an optical distributor which distributes the optical signal outputted in the electrophotic conversion module to an optical signal for monitoring and an optical signal for transmitting; an optical transmission processing unit which transmission processes the optical signal for transmitting distributed in the optical distributor through an optical subscriber network; and a diagnosis module which converts the optical signal for monitoring distributed in the optical distributor to an electrical signal to diagnose the electrophotic converted optical signal for transmitting. The optical transmission device for transmitting a broadcast signal through an optical subscriber network allows self-monitoring the transmission status of the optical signal after converting the RF broadcast signal to the optical signal, thereby easily responding to the transmission failure.
