The present disclosure provides an optical fiber receptacle, an optical fiber connection device and an optical fiber receptacle module. The optical fiber receptacle comprises a housing, a plurality of positioning hooks and at least one clamping unit. The housing has a rear wall, and at least one slot opened on an opposite side of the rear wall. The rear wall has an inner surface facing the slot and an outer surface opposite to the inner surface, the slot is used to be inserted by an optical fiber plug. The positioning hook protrudes from the outer surface of the rear wall in a column shape, is used to pass through a mounting hole of a panel to latched with a hole edge defining the mounting hole of the panel. The clamping unit is formed to the rear wall corresponding to the slot and comprises a clamping channel penetrating the rear wall and communicated with the corresponding slot for clamping a holding member of the optical fiber joint so that the first ferrule of the optical fiber plug and the second ferrule of the optical fiber joint are connected relative to each other. The optical fiber receptacle of the present disclosure can reduce the volume and greatly reduce the material costs.
