    • A transceiver module for optical communication includes a light-emitting element, a light-receiving element and a rod lens. Light from the light-emitting element is condensed onto the top end of the rod lens. A ferrule of an optical fiber is brought into physical contact with the top end surface of the rod lens so as to couple the light-emitting element and the light-receiving element with the optical fiber. The rod lens is held by a support supported by a spring member on a housing, and the outer diameter of the rod lens is formed so as to be substantially equal to the outer diameter of the ferrule. An opening portion is provided in the housing so that the top end of the ferrule of the optical fiber is slidably fitted into one end of a sleeve, the other end of which is slidably fitted onto the outer circumference of the rod lens. Also, a transceiver module includes a light-emitting element for emitting transmission signal light, a coupling lens for connecting the transmission signal light emitted from the light-emitting element to a light transmission path, and a light-receiving element for receiving detection signal light from the light transmission path, in which the transmission signal light emitted from the light-emitting element is reflected on a surface of the light-receiving element and connected to the light transmission path through the coupling lens; and the detection signal light from the light transmission path is received by the light-receiving element.
    • 用于光通信的收发器模块包括发光元件,光接收元件和棒状透镜。 来自发光元件的光会聚到棒状透镜的顶端。 将光纤的套圈与棒状透镜的顶端面物理接触,以将光发射元件和光接收元件与光纤耦合。 棒状透镜被由壳体上的弹簧构件支撑的支撑件保持,并且棒状透镜的外径形成为基本上等于套圈的外径。 开口部设置在壳体中,使得光纤的套圈的顶端可滑动地嵌合在套筒的一端中,套筒的另一端可滑动地装配到杆状透镜的外圆周上。 此外,收发器模块包括用于发射透射信号光的发光元件,用于将从发光元件发射的发射信号的光连接到光传输路径的耦合透镜,以及用于接收检测信号光的光接收元件 从光发射元件发射的发射信号光在光接收元件的表面上被反射并通过耦合透镜连接到光传输路径的光传输路径; 并且来自光传输路径的检测信号光被光接收元件接收。
