  • Publication number: 20110287661
    Abstract: A coaxial switching jack with a pair of coaxial assemblies mounted within a housing having a pair of front cable connection locations is disclosed. The coaxial assemblies each include a center conductor and an outer shield conductor. The center conductors are connected by a first spring and the shell conductors are connected by a second spring. Insertion of a coaxial cable connector within one of the front cable connection locations deflects the springs from the corresponding coaxial assembly and disconnects the center and shell conductors of the two assemblies. The jack may also be configured to provide an electrical connection between the center and shell conductors of the second coaxial assembly if a coaxial cable connector is inserted within the first coaxial assembly. The connection between the center and shell conductors of the second coaxial assembly may be through a resistor assembly allowing for selection of a desired electrical impedance.

  • Patent number: 8041177
    Abstract: A dust cap and a dust plug for installation with optical fiber connectors and optical fiber adapters respectively. The dust cap and the dust plug have features that protect an optical interface on the optical fiber connector and the optical fiber adapter from contamination. At least an exterior portion of the dust cap and the dust plug illuminate when installed on the optical fiber connector and the optical fiber adapter terminating an optical fiber transmitting visible light. The dust cap and the dust plug have features that reduce the intensity of a high power optical signal emitted from the optical fiber terminated by the optical fiber connector and optical fiber adapter. A first embodiment diffracts the optical signal, thereby reducing its intensity. A second embodiment disburses the optical signal, thereby reducing its intensity. A third embodiment absorbs high power frequencies of the optical signal and transmits certain visible frequencies.
