Multi-channel ROF system and implementation method

Abstract

The invention relates to a multi-channel ROF system and an implementation method. Eight paths of radio frequency signals are respectively input to eight optical transfer insertion boxes of optical terminal equipment I for electro-optical transform; eight paths of optical signals are output; the eight paths of optical signals are respectively transmitted to eight optical receiving insertion boxes of optical terminal equipment II through an optical cable; the optical receiving insertion box carries out optical-electro transform on the eight paths of transmitted optical signals; eight paths of radio frequency signals are restored; remote transmission of the eight paths of radio frequency signals is completed; or the eight paths of radio frequency signals are respectively input to eight optical transfer insertion boxes of the optical terminal equipment II for electro-optical transform; eight paths of optical signals are output; the eight paths of optical signal are respectively transmittedto eight optical receiving insertion boxes of the optical terminal equipment I through the optical cable; the optical receiving insertion box performs optical-electro transform on the eight paths oftransmitted optical signals; eight paths of radio frequency signals are restored; and remote transmission of the eight paths of the radio frequency signals is completed.
