Abstract: An optical signal converting apparatus and a method thereof are provided to transmit an analog time synchronization signal at a long distance by converting the analog time synchronization signal to a digital signal and transmitting the converted signal through an optical cable. An optical signal converting apparatus includes a first signal processing part(110), a second signal processing part(120), and a synthesizing part(130). The first signal processing part compares an analog time synchronization signal with a first critical value, converts the analog signal to a digital signal, and outputs the converted digital signal. The second signal processing part outputs a digital signal corresponding to a zero crossing point of the analog time synchronization signal. The synthesizing part synthesizes and outputs the signals outputted from the signal processing parts.

Abstract: A system for distributing a clock synchronization signal and a method therefor are provided to acquire a room space and reduce an installation cost by generating various sorts of clock synchronization signals with one GPS satellite clock receiver and one clock synchronization signal distribution device without an additional GPS satellite clock receiver. A system for distributing a clock synchronization signal includes an input unit(110), a control unit(120), an output unit(130), and a determination unit(140). The input unit receives a clock synchronization signal. The control unit generates a plurality of different clock synchronization signals using the inputted clock synchronization signal. The output unit outputs the generated different clock synchronization signals. The determination unit determines whether the clock synchronization signal is inputted. The input unit receives the clock synchronization signal from at least one of a GPS satellite clock receiver and a different clock synchronization signal distribution device.
