    摘要: A method of fabricating a WDM unit consists of attaching a first and a second GRIN lenses to opposite faces of a WDM filter. A dual fiber pigtail and a single fiber pigtail are mounted in corresponding glass tubes. The glass tube with the dual fiber pigtail and the glass tube with the single fiber pigtail are mounted on the second GRIN lens and the first GRIN lens respectively. The position of the dual fiber pigtail and the single fiber pigtail are adjusted with respect to the second GRIN lens and the first GRIN lens respectively to obtain the best optical property. The invention prevents the WDM filter from tilting during temperature variation by sandwiching the WDM filter in between the two GRIN lenses, and further prevents the WDM unit from increasing the reflection loss and insertion loss.

    摘要: A fiber container receiving optical fibers has a body, a space defined in the body, a reel disposed inside the body, wherein a groove is defined around the periphery of the reel. The optical fibers are twisted around the reel and received in the groove. Furthermore, the fiber container is able to apply to the active/passive optical communication device, such as an erbium doped fiber amplifier (EDFA) or a dense wavelength division multiplexer (DWDM).

    摘要: A highly reliable optical add/drop device is described. The optical add/drop device has an external tube and a ring, wherein the external tube and the ring are made of metallic material. A WDM filter is fixed in the ring. The ring is inserted in the external tube at the middle portion and fixed therein by soft solder technique. A single fiber collimator and a dual fiber collimator are respectively coupled with the opposite surfaces of the filter, and aligned in the external tube. Additionally, the single and dual fiber collimators are also fixed therein by soft solder technique, as two metal tubes respectively hold the single and dual fiber collimators. In the invention, the WDM filter is rigidly fixed to avoid tilting during temperature variation. Moreover, the invention provides an optical add/drop device with low insertion loss and reflection loss.
