Abstract: An electrical signal transmission system includes a plurality of elongated conductors extending in a generally parallel array. The conductors have input ends at one end of the array and output ends at an opposite end of the array. Each conductor includes an elongated intermediate section and transition sections at opposite ends of the intermediate section joining the intermediate section to the input and output ends of the conductor. The array of conductors define two outside pairs of conductors and at least one inside pair of conductors. The elongated intermediate sections of the conductors in the inside pair thereof being spaced apart wider than the elongated intermediate sections of the conductors in each outside pair thereof.

Abstract: A replaceable module is provided for attachment to a standard fiber optic connector and an opto-electronic device on a printed circuit board. The module is mounted between the internal assembly and the external assembly of a fiber optic connector. The module is easily replaceable without requiring access to the interior side of the mounting panel and without requiring disconnection of the internal assembly from the opto-electronic device on the printed circuit board. Use of the replaceable module when connecting to an external device results in reduced wear on the internal assembly, thereby enabling an increase in the number of mating cycles that the internal assembly is able to perform.

Abstract: A shielded electrical connector is provided for mounting at least partially in a cut-out portion of a printed circuit board. The connector includes a dielectric housing having an opening through a bottom wall thereof coincident with the cut-out portion of the printed circuit board. The housing has a plug-insertion cavity with an opening at a front mating face thereof for receiving a complementary mating plug connector. A latch projection extends from the housing near the opening in the bottom wall thereof. A metal shield is mounted about the housing and has a front plate portion juxtaposed over the front mating face of the housing and having a plug-insertion opening aligned with the front opening of the housing. The shield includes a bottom plate portion aligned with the opening in the bottom wall of the housing and including a latch aperture for embracing the latch projection of the housing.
