Abstract
An optical transmission module or an optical module has a receptacle attached adjacent to an optical component module or package, and a plug configured to connect vertically with the receptacle from above the module. The outer peripheral shape of the housing is designed to fit within an area of the receptacle that faces upwardly to receive the plug in an insertion direction extending vertically downwardly. In the housing of the plug, a ferrule is attached to an end of an optical fiber and a sleeve covers the optical fiber and the ferrule. A knob is used for moving the optical fiber, the sleeve and the ferrule in the lightwave propagation direction, which is transverse to the plug insertion direction.
