The present invention provides a dot-matrix prefabricated optical cable and a manufacture method thereof. The dot-matrix prefabricated optical cable comprises a cable; a male terminal assembly located at one end in the cable and configured for connection; a female terminal assembly located at one end, far away from the male terminal assembly, in the cable and configured for matching usage with the male terminal assembly; and a mounting base 4 configured to fix and connect the male terminal assembly with the female terminal assembly. The manufacture method provided by the invention comprises: injection molding, solidification, optical fiber cutting, grinding, waxing and the like. According to the dot-matrix prefabricated optical cable, the defects of cable welding construction on site and the deficiency of the ceramic pin prefabricated connector may be overcome; and moreover, the size is small, the optical fiber intensity is high, the insertion is easy and the insertion loss is low, etc. There is not provided the welding technology in the prefabrication process, therefore the standardized design and the industrialized production may be achieved with obvious economic value and high practicability.
