Optical-fiber adapter

An optical-fiber adapter comprising:

• an adapter body, wherein two ends of the adapter body have a first mating side and a second mating side;
• four side walls of the adapter body define a receiving cavity, the first mating side of the adapter body has a first insertion opening in communication with the receiving cavity, and the second mating side of the adapter body has a second 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;
• a base component retained in the receiving cavity;
• and
• a conductive module comprising a plurality of conductive terminals, wherein 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.
