Optical-fiber adapter

An optical-fiber adapter comprising:

• an adapter body, wherein one end of the adapter body has a mating side;
• four side walls of the adapter body define a receiving cavity, and the mating side of the adapter body has an insertion opening in communication with the receiving cavity;
• the four side walls of the adapter body are a first side wall, a second side wall, a blocking wall, and a combining base wall, respectively;
• the first side wall and the second side wall of the adapter body are respectively connected to two sides of the combining base wall and two sides of the blocking wall;
• the adapter body has an assembling groove at the combining base wall and in communication with the receiving cavity;
• an optical transceiver module retained in the receiving cavity;
• a conductive module retained in the receiving cavity and abutting against one of two sides of the optical transceiver module, wherein the conductive module comprises a plurality of conductive terminals, one of two ends of each of the conductive terminals is in the receiving cavity and adjacent to the assembling groove, and the other end of each of the conductive terminals extends out of the assembling groove from the receiving cavity;
• and
• a positioning base retained in the receiving cavity and abutting against the other side of the optical transceiver module, wherein two sides of the positioning base have a plurality of grooves and a plurality of positioning portions, and the positioning portions are adjacent to openings of the grooves.
