Abstract: A method for generating a visible signal for a data transmission frame and an apparatus therefor are provided to perform high-speed communication with the small power and low cost in the visible light communication network having a limited distance. An apparatus for generating a visible signal receives specific data consisting of a plurality of frames from a transmission side(510). A VLC controller converts an RSSI signal measured from the transmission side into a digital signal(512), and checks RSSI signals of each corresponding frame whenever each frame of the specific data is sequentially received from the transmission side(514). The corresponding RSSI value of a received frame is a preset critical value or greater(516), the VLC controller produces visible signals differentiated according to each RSSI state, and then transmits the generated signals to the transmission side(518).

Abstract: A two-way PON(Passive Optical Network) is provided to be easily manufactured, and to use a broadband light source of a linearly polarized component, thus coupling loss can be minimized while the efficiency of wavelength-locking is increased. A PON(200) comprises the followings. A CO(Central Office)(210) generates uplink/downlink beams having linearly polarized modes, and generates multiplexed downlink optical signals, which are wavelength-locked by the downlink beam and have linearly polarized modes orthogonal to the downlink beam. An RN(Remote Node)(230) demultiplexes the downlink optical signals, and multiplexes the uplink optical signals to output the multiplexed signals to the CO(210). Plural ONUs(Optical Network Units)(240-1~240-N) detect downlink optical signals of the corresponding wavelength, and generate the respective uplink optical signals wavelength-locked by the uplink beam of the corresponding wavelength to output the generated signals to the RN(230). The first optical line(201) links the CO(210) with the RN(230).
