Abstract: An optical cable and method for forming an optical cable is provided. The cable includes a cable jacket including an inner surface defining a channel and an outer surface. The cable includes a seam within the cable jacket that couples together opposing longitudinal edges of a wrapped thermoplastic sheet which forms the cable jacket and maintains the cable jacket in the wrapped configuration around the plurality of optical fibers. The method includes forming an outer cable jacket by wrapping a sheet of thermoplastic material around a plurality of optical core elements. The method includes laser welding together portions of thermoplastic material of opposing longitudinal edges of the wrapped sheet such that a seam is formed holding the sheet of thermoplastic material in the wrapped configuration around the core elements.

Abstract: A variable impedance interface device connecting a coaxial connector to an external component with a housing having a first end adapted to receive a coaxial connector and a second end having an interface where the housing is attachable to an external component, such as a printed circuit board. A cavity within the housing is defined by an inner surface and has a cavity first end and a cavity second end. The inner surface tapers between the cavity first end and the cavity second end. A mating position in the cavity has a certain dimension due to the taper of the inner surface, and defines a location at which a coaxial connector received by the housing positions. An impedance of the housing is based on the mating position and may be varied due to the impedance of the interface such that signal degradation at the interface is reduced.

Abstract: The differential pair system includes a push-on high frequency differential interconnect and push-on high frequency differential connector. The system allows for blind mating of the two components, using a keying system for the two electrical conductors to be axially and radially aligned.

Abstract: An electrical connector has first and second connector bodies. The first connector body has an inclined surface and the second connector body has arms that correspond to the inclined surfaces. At the end of the inclined surfaces are generally flat portions forming a ledge that prevent the connector bodies from separating. To unmate the connector bodies, one connector body is rotated relative to the other, causing the arms to move from the generally flat portion to the outer surface of the second connector to allow them to be moved axially away from one another.

Abstract: Apparatus is described for transmitting signals between electric terminals through photo diodes to electrically isolate circuits connected to the terminals, which is compact and rugged. The apparatus includes a metal shell, (24, FIG. 2) a pair of circuit boards (40, 42) mounted in the shell and axially spaced apart, pairs of terminals (12, 14) with one terminal of each pair mounted on a different one of the circuit boards, and pairs of photo diodes or other optoelectric transducers (16, 18). Each transducer of a pair is mounted to a different circuit board and connected to a corresponding terminal, and the two transducers are aligned and extend toward each other. A separator element (90) of opaque material occupies most of the space between the circuit boards and has holes (92) that receive the two transducers of each pair. The separator element prevents the leakage of light between different pairs of transducers, and also helps to assure alignment of each pair of transducers.

Abstract: An optoelectric connector (12, FIG. 2) is described, which has an outer end (96) constructed to efficiently couple to an optical fiber connector (14) and which has an inner end (47) with electrical contacts (46) for passing currents representing modulated light received or transmitted to an optical cable (20) attached to the optical connector. The optoelectric connector (12) includes a stub (80) or short length of optical fiber with an outer end (82) held at a coupling that couples to the optical fiber (24) of the cable in the same manner as a pair of long optical fibers are connected to minimize losses. The stub has an inner end (84) optically coupled to the optic face (42) of a photoelectric transducer (40) which is coupled to an electrical contact (46).
