    摘要： A variable optical attenuator (99) comprises a holder (4), a rotatable mechanism (5), a refractor (6), an input port (2) and an output port (3). The input port and the output port are engaged with corresponding upright beams (42, 43) of the holder, which hold the input port and the output port in alignment with each other. The refractor is mounted on the rotatable mechanism by adhering to or soldering on a groove (52) of the rotatable mechanism, wherein the rotatable mechanism mates with a through hole (46) of the holder to make the center of the refractor and the optical axis of input and output collimators (22, 32) of the input and output ports in line.

    摘要： An optical collimator (20) includes an optical fiber (21), a metal ferrule (22), a Graded Index (GRIN) lens (23) and an outer metal tube (24). The optical fiber has an exposed end (211) which is coated with metal. The exposed end of the optical fiber is inserted into the ferrule and laser welded thereto. The GRIN lens is also coated with metal. A plurality of soldering holes (241) is defined in a periphery of the outer tube. Solder is applied to the ferrule and the GRIN lens through the holes to firmly connect the outer tube, the ferrule and the GRIN lens together. After assembly, if the position of the GRIN lens or the optical fiber is found to be inaccurate, the GRIN lens and the ferrule can be easily resoldered.

    摘要： An optical attenuator includes an input optical fiber (11) and an attenuating device (3). The attenuating device is a neutral density (ND) filter. The filter has a refractive index matching that of the input optical fiber, to reduce Fresnel reflectance between the attenuating device and a terminal of the input optical fiber. One surface of the ND filter is not perpendicular to an incident light beam, thus preventing multireflectance between the attenuating device and the terminal of the input optical fiber. Therefore, return loss is increased.

    摘要： An electrical connector in a portable telecommunication device with a built-in antenna to enable the device to connect with an external antenna, comprises a dielectric housing having a base portion defining first and second chambers communicating with each other via a passage, and a cylindrical portion defining a hole therethrough in communication with the first chamber, a first contact fixedly received in the first chamber and electrically connecting with speaker/receiver circuitry of the device and a second contact fixedly received in the second chamber and electrically connecting with the built-in antenna. When the connector does not connect with a mating connector in electrical connection with an external antenna, the first contact electrically engages with the second contact by a spring force generated from the first contact. When the connector is connected with a mating connector in connection with an external antenna by extending a conductive pin of the mating connector through the hole in the cylindrical portion into the first chamber, the pin engages with the first contact and prevents it from engagement with the second contact.
