ABSTRACT:
An optical receptacle includes a housing having a base end and a nose end. From the base end of the housing is fitted the first ferrule. A split sleeve is provided in the housing. In the split sleeve is fitted the second ferrule of an optical fiber connector plug to be connected to the nose base side of the housing so that the first and second ferrules are aligned with each other. At the base end of the housing are provided first hook portions for holding the first ferrule while at the nose end are provided a fitting portion for fitting an optical fiber connector and second hook portions for holding the optical fiber connector plug in the fitting position thereof. The housing includes an inner part and an outer part having fixed therein the inner part. The inner part is composed of the first and second hook portions integrally molded. The outer part holds the optical fiber connector plug and hold therein the inner part fixedly. The optical receptacle has a simplified structure without adverse affect on the function of the device, thus achieving down-sizing and reduction in weight.
