    Abstract: An optic adaptor connects first and second optic fibers in an aligned but spaced fashion for attenuation of optic signal traveling between the optic fibers. The adaptor includes a base secured to a patch panel and connected to the first optic fiber. The base defines a bore receiving and retaining a first end of a sleeve that receives the first optic fiber. A cylinder has a proximal end axially and movably received in the bore to receive a second end of the sleeve. A fiber connection member is mounted to the cylinder and attaches the second optic fiber to the cylinder with the second optic fiber received in the second end of the sleeve. A knob ring threadingly engages the cylinder. The knob is rotatably mounted to but is not axially movable with respect the base body whereby rotation of the knob induces axial movement of the cylinder and the second optic fiber with respect to the base body and the first optic fiber. Thus the distance between the optic fibers can be changed.

    Abstract: An optical fiber holding device (100) comprises a fastening flange (120) and a coil-shaped fiber receiving portion (110) connecting with the flange. The receiving portion is formed by a wall (113) spiraling from an inner end (114) thereof outwardly. A central holding space (112), a spiral guiding passage (111), and an inlet (115) of the passage are thereby defined. The flange is connected with an outer end of the wall adjacent the inlet. A pair of through holes (121) is defined in the flange. The holding device is integrally formed by molding plastic material, or by bending a metal sheet. Each optical fiber (130) is inserted into the inlet, guided along the passage, and received in the central holding space. Screw s are extended through the through holes to secure the holding device together with the optical fibers to an optical module.

    Abstract: A holding device (200) used for a DWDM module. The holding device comprises a base (201), a plurality of projections (209), a plurality of C-shaped grooves (205) interleavingly defined between the projections, and a plurality of C-shaped slots (210) defined in upper portions of the projections respectively. An upper portion of each projection forms two chamfers (211, 212), on opposite sides of the corresponding slot. The chamfers extend inclinedly upwardly in a mutually diverging manner. The upper portion of each projection also forms two opposite slanted faces (207, 208). Two slanted faces of any two projections that oppose each other across an intervening groove extend inclinedly upwardly in a mutually diverging manner. The grooves hold sleeves (101) that enclose DWDMs (100). The slots hold optical fibers (102) of and connecting with the DWDMs.

    Abstract: An optical switch includes an input port (51), a plurality of output ports (52), a switching element (40) for switching light signals from the input port to any one of the output ports, a base (30), and a housing (10). The switching element has a driving device (400), a rotary holder (410) and two reflectors (422, 424). The reflectors are attached to a supporting arm (414) of the rotary holder, and positions of two counterweights (418) are adjustable on two balancing arms (416) to balance the combination rotary holder—reflectors around an axis of rotation. The input port is mounted in a center hole (352) of the base and the output ports are mounted in peripheral holes (354) defined in a circle around the center hole. Rotation of the rotary holder switches light signals from the input port to be output to any one of the output ports.

    Abstract: An optical switch (1) having a sealing system connects to input fibers (42, 43) and output fibers (44, 45), and includes a switching device (5), a top housing (10), a bottom housing (30), a gasket (20) and four fiber clamps (40). The top and bottom housings each define a ringed channel (104, 304). The gasket is received in the ringed channels of the top and bottom housings. When screws combining the top and bottom housings together are tightened, the gasket deforms to fill the ringed channels, thereby forming a good seal between an inside and an outside of the housing.

    Abstract: An optical switch (1) having a sealing system connects to input fibers (42, 43) and output fibers (44, 45), and includes a switching device (5), a top housing (10), a bottom housing (30), a gasket (20) and four fiber clamps (40). The top and bottom housings each define a ringed channel (104, 304). The gasket includes a plurality of quadrate flanges (206). Each quadrate flange defines an elliptic opening (208) for inserting a fiber clamp holding a fiber. The gasket is received in the ringed channels of the top and bottom housings. When screws combining the top and bottom housings together are tightened, the gasket deforms to fill the ringed channels, thereby forming a good seal between an inside and an outside of the housing. The elliptic openings promote a balancing of stress in the quadrate flanges, increasing the life of the gasket.
