SYSTEM FOR LOCAL NETWORK OF PASSIVE OPTICAL NETWORK AND OPTICAL SIGNAL TRANSMISSION METHOD THEREOF

摘要

PURPOSE: A local network system of a passive optical network and an optical signal transmission method thereof are provided to distribute an optical signal transmitted from an arbitrary subscriber connected to the passive optical network to other subscribers in order to configure a local network between subscribers. CONSTITUTION: Multiple optical modems(160) transceive a first optical signals for communication between a base station and a subscriber and a second optical signal for communication between the subscribers. A selective light transmission body(140) penetrates the first optical signal. The selective light transmission body reflects the second optical signal transmitted from at least one optical modem among the multiple optical modems to the multiple optical modems. An optical distribution unit(130) distributes the reflected second optical signal to the multiple optical modems.
