The tongue portion defines a recess at a front end thereof and a first through hole, the recess engaging with a forehead of the first and second contact modules, the first through hole receiving the first and second contact modules while exposing the exposed upper surface of the first embedded portion and the exposed lower surface of the second embedded portion.

Abstract: A mounting assembly includes a mounting bracket (10) having a side panel (14), and a clip (40) attached on the side panel. A pair of through holes (18) is defined in the side panel. The clip includes a press portion (42), and a pair of palms (48) on opposite sides of the press portion. Each palm has barbs (49) extending toward the press portion. When the press portion is inwardly pressed, the clip elastically deforms, the palms move away from each other, and the palms extend through the through holes to be received in corresponding locking holes (32) defined in a corresponding data storage device (30). The barbs firmly engage with the storage device at the locking holes, thereby securing the storage device in the mounting bracket. When the press portion is inwardly pressed again, the storage device is unlocked from the mounting bracket.

Abstract: A variable attenuator assembly (1) includes a variable attenuating connector (VAC) (11), a coupling sleeve (12), and a second plug-type connector (13). The VAC includes a housing (20) and an attached double screw mechanism (110). The double screw mechanism is finely adjustable because it uses an adjusting knob (40) having a set of external threads (401) and a set of internal threads (402) with two different screw pitches. The external threads engage with an internally threaded bore (303) of a connecting nut (30) attached to the housing. The internal threads engage with outer threading (602) on a ferrule holder (60) received in the adjusting knob. When the adjusting knob is rotated, the knob moves in one direction, and the ferrule holder is moved in the opposite direction, the total distance of ferrule holder movement relative to the housing being proportional to the difference between the screw pitches.

Abstract: A tunable filter (4) includes a thin film filter (2) and an electric controller (3). The thin film filter includes a transparent substrate (28) and a thin film filter stack (20). The thin film filter stack is constructed as a Fabry-Perot etalon, including a central spacer (26) and two multi-reflective layers (22, 24) respectively on opposite sides of the spacer. One multi-reflective layer is an H(LH)P−1 film system, the other multi-reflective layer is an (HL)P−1H film system. The spacer includes a transparent dielectric film having an optical thickness equal to one half of a predetermined transmitting central wavelength. The transparent dielectric film is made of piezoelectric material whose optical thickness is controllably variable. The controller receives and analyzes optical signals, and automatically controls the thin film filter stack to allow passage of the transmitting central wavelength. The control is achieved by adjusting an optical thickness of the central spacer.
