Abstract: The present invention relates to an optical relay system that transmits a band-limited multi-band frequency signal via an optical line. A base station interface unit combines a plurality of band-limited wireless signals into one wireless signal, and an optical distribution unit converts the combined wireless signal into an optical signal and optically transmits it to a remote unit. Therefore, the number of optical modules and optical cores used for optically transmitting a wireless signal can be reduced, so that the signal noise ratio (SN) of the system can be improved, equipment can be miniaturized, and manufacturing cost can be reduced.

Abstract: The present invention relates to an optical relay system for transmitting multi-band frequency signals with limited bands by using optical lines. According to the present invention, a plurality of band-limited signals are band-combined into one signal by using a combiner, and the signals are transmitted through multiple outputs by using a distributor, and thus a multi-stage filter is not necessary. In addition, the present invention is capable of effectively solving various problems such as damage to the original signals caused by the band combination of the multi-stage filter, and there is no need to precisely connect each of the band-limited signals to the determined ports of the combiner and the signals can be connected to random ports, thereby improving convenience of use.

Abstract: The present invention relates to an optical relay system that transmits a band-limited multi-band frequency signal via an optical line. According to an embodiment of the present invention, since a remote unit includes a multiplexer that fixes a power flow direction to combine wireless signals of various bands and outputs the combined signals to a mobile terminal, or distributes wireless signals wireless signals received from the mobile terminal and fixes a power flow direction to output the distributed wireless signals, even if frequency bands of signals combined by the multiplexer overlap or are adjacent, power delivery in a direction opposite to the power delivery direction of a signal during a signal combining process can be prevented, reducing signal distortion, and thus improving efficiency in combining a number of signals.
