The present invention provides an optical module, a plug for connecting an optical fiber, or an optical coupler provided with a configuration that permits the connection of an optical fiber without using a ferrule. For this purpose, the optical module, the plug for connecting an optical fiber, or an optical coupler equipped with the same is provided with: a substrate (,); an optical device (,) mounted on the substrate; a connecting optical fiber (,), one end of which is positioned with respect to the optical device, and the distal end of a transmitting optical fiber to be connected is positioned with respect to the other end thereof; and a guide (,) for guiding the distal end of the transmitting optical fiber to be connected. The distal end of the transmitting optical fiber is positioned with respect to the first end of a connecting optical fiber by disposing the distal end of the transmitting optical fiber in the guide.

Optical module, optical fiber connecting plug, and optical coupler equipped with the same

An optical connector comprises a housing having a ferrule holding portion for holding a ferrule to be connected to an optical fiber, wherein said ferrule is equipped with a split sleeve for implementing an alignment with a ferrule of a mate connector, and said ferrule holding portion has a ferrule holding through passage which allows said ferrule to be received along the direction of ferrule diameter, allows said split sleeve to be inserted along the axial direction of said sleeve, and allows said ferrule to be installed into and held to said housing.

Optical connector

An optical semiconductor module structure comprises a housing which has an optical coupling means comprising an optical semiconductor element and a ferrule accommodating an optical fiber therein, a portion of said housing for holding said ferrule being formed to be a protuberant portion, wherein said optical semiconductor module structure is provided with, for coupling an optical connector with said protuberant portion, a means for regulating said optical connector in the direction of the axis of said ferrule and a means for regulating said optical connector in a direction right to the axis of said ferrule.
