    • An optical semiconductor module including a housing (54), an optical semiconductor assembly (56), a movable ferrule (84), and a sleeve (60). The housing (54) has a hole (80) into which a connector ferrule (76) is inserted. The optical semiconductor assembly (56) is accommodated in the housing (54). An optical fiber (74,82) having a first end (82a) and a second end (82b) is fixed in the movable ferrule (84). The movable ferrule (84) has a thin hole (84a) in which the second end (82b) of the optical fiber (82) is inserted and fixed. The first end (82a) of the optical fiber (82) is supported so as to be optically coupled to the optical semiconductor assembly (36). The sleeve (60) is accommodated in the hole (80) of the housing (54), so as to align the movable ferrule (84) and the connector ferrule (76) with each other. The movable ferrule (84) is biased so as to be pressed against the connector ferrule (76) in the sleeve (60). With this configuration, even if an optical connector is repeatedly mounted/demounted with respect to the optical semiconductor module, a high efficiency of optical coupling between the optical connector and the optical semiconductor assembly (56) can be stably maintained, thus providing an optical semiconductor module having a high reliability.
    • 一种光学半导体模块,包括壳体(54),光学半导体组件(56),可移动套圈(84)和套筒(60)。 壳体(54)具有插入连接器套圈(76)的孔(80)。 光学半导体组件(56)容纳在壳体(54)中。 具有第一端(82a)和第二端(82b)的光纤(74,82)固定在可动套圈(84)中。 可移动套圈(84)具有插入并固定光纤(82)的第二端(82b)的细孔(84a)。 光纤(82)的第一端(82a)被支撑以光学耦合到光学半导体组件(36)。 套筒(60)容纳在壳体(54)的孔(80)中,以使可动套圈(84)和连接器套圈(76)彼此对准。 可移动套圈(84)被偏置以便被压靠在套筒(60)中的连接器套圈(76)上。 利用这种结构,即使相对于光学半导体模块重复地安装/拆卸光连接器,也可以稳定地保持光连接器和光半导体组件(56)之间的高效率的光耦合,从而提供光半导体 模块具有高可靠性。
