    • An optical module which satisfies a required insertion loss and can be easily assembled with high productivity. The optical module includes first optical fiber, a first lens, an optical device, a second lens, and second optical fiber. The first lens receives an incident light from the first optical fiber and converts the incident light into a parallel light. The optical device receives the parallel light and performs predetermined optical processing on the parallel light. The second lens receives a transmitted parallel light from the optical device and converge the transmitted parallel light to produce an outgoing light. The second optical fiber receives the outgoing light. An optical axis of the first lens and an optical axis of the second lens are substantially coincident with each other. An optical axis of the first optical fiber and an optical axis of the second optical fiber are substantially parallel with each other and substantially parallel to the optical axes of the first and the second lenses.
    • 一种满足所需插入损耗并且可以以高生产率容易地组装的光学模块。 光学模块包括第一光纤,第一透镜,光学装置,第二透镜和第二光纤。 第一透镜接收来自第一光纤的入射光并将入射光转换成平行光。 光学装置接收平行光并对平行光进行预定的光学处理。 第二透镜从光学装置接收透射的平行光,并且会聚发射的平行光以产生出射光。 第二光纤接收出射光。 第一透镜的光轴和第二透镜的光轴基本上彼此重合。 第一光纤的光轴和第二光纤的光轴基本上彼此平行并且基本上平行于第一和第二透镜的光轴。
