    • The present invention provides an optical module for light-transmitting a first optical signal with a first wavelength and light-receiving a second optical signal with a second wavelength in bidirectional. The optical module of the invention includes an optical fiber, a laser diode, a photodiode, an optical filter and a holder for securing the optical filter. The laser diode emits the first optical signal, while the photodiode receives the second optical signal. The filter reflects one of the first and second optical signals and transmits the other of first and second optical signals. The holder of the present invention includes first and second lens both built in the surface of the holder. The first lens faces the laser diode and optically couples the laser diode with the optical fiber, while the second lens faces the optical fiber. Since the first and second lenses are built in the surface of the holder, the optical alignment of the laser diode and the photodiode can be automatically carried out by mounting the laser diode and the photodiode on the surface of the holder.
    • 本发明提供了一种光学模块,用于对具有第一波长的第一光信号进行光传输,并且光接收具有双向的第二波长的第二光信号。 本发明的光学模块包括光纤,激光二极管,光电二极管,滤光器和用于固定滤光器的保持器。 激光二极管发射第一光信号,而光电二极管接收第二光信号。 滤光器反射第一和第二光信号中的一个,并透射第一和第二光信号中的另一个。 本发明的保持器包括构成保持器表面的第一和第二透镜。 第一透镜面对激光二极管并且将激光二极管与光纤耦合,而第二透镜面对光纤。 由于第一透镜和第二透镜被构建在保持器的表面中,因此可以通过将激光二极管和光电二极管安装在保持器的表面上来自动执行激光二极管和光电二极管的光学对准。

    • The present invention provides an optical receptacle having a superior insertion/extraction performance of the ferrule, and an optical sub-assembly applying the optical receptacle. The optical receptacle 1 includes a stub, a bush 4, a sleeve, and a sleeve cover. The stub having a lower portion covered by the bush, and an upper portion covered by the sleeve. The sleeve may be a rigid sleeve without any slit along the optical axis in its outer surface. The sleeve cover covers the sleeve and the bush. In the present optical receptacle, the bush is press-fitted into the gap formed between the stub and the sleeve cover. Accordingly, in addition to the application of the rigid sleeve, not only the sub is hard to slide out from the sleeve, but also the insertion/extraction performance of the ferrule to be inserted into the sleeve may be enhanced.
    • 本发明提供了一种具有插座/拔出性能优异的光学插座以及应用该光插座的光学子组件。 光学插座1包括短棒,衬套4,套筒和套筒盖。 该短截线具有由衬套覆盖的下部,以及由套筒覆盖的上部。 套筒可以是刚性套管,其外表面上没有沿光轴的任何狭缝。 袖套覆盖套管和衬套。 在当前的光学插座中,衬套被压配合到形成在短棒和套筒盖之间的间隙中。 因此,除了刚性套筒的应用之外,不仅子系难以从套筒滑出,而且可以提高插入到套筒中的套圈的插入/取出性能。
