Abstract: A system and method are disclosed in which flex cables are affixed to PCBs, for providing high-speed signaling paths between ICs disposed upon the PCBs. The flex cables are fixably attached to the PCBs so as to substantially mimic their structural orientation. Where the configuration includes more than one PCB, the flex cables include multiple portions which are temporarily separable from one another and from the die, using flex-to-flex and flex-to-package connectors, allowing field maintenance of the configuration. By routing the high-speed signals between ICs onto the flex cable, single-layer PCBs can be used for non-critical and power delivery signals, at substantial cost savings. By disposing the flex cables onto the PCB rather than allowing the cables to float freely, the configuration is thermally managed as if the signals were on the PCB and cable routing problems are avoided.

Each signal conductor has a first contact end connectable to a printed circuit board, a second contact end, and an intermediate portion having a first width. For each differential pair, one first contact end lies along a first line parallel to the plurality of rows and the other first contact end lies along a second line parallel to and spaced from the first line. The differential connector further includes a plurality of ground conductors, with each ground conductor corresponding to a differential pair. Each ground conductor has a first contact end connectable to the printed circuit board, a second contact end, and an intermediate portion having a second width that is at least twice the first width.

Abstract: An apparatus for terminating a transmission line includes a terminating circuit coupled to a first connector portion. A second connector portion mates with the first connector portion. The second connector portion is coupled in electrical contact with the transmission line and includes one or more components, such as pins, that can radiate unwanted electromagnetic interference (EMI) when the transmission line is not terminated. The terminating circuit includes components, such as one or more resistors, that substantially match the impedance of the transmission line. The terminating circuit can also be configured to terminate other conductive lines that can pick up signal noise in a system. The terminating apparatus can be utilized on operational boards that plug into devices such as backplanes or mid-planes. Alternatively, the terminating circuit can be included on a null device or built into the first connector portion.

Abstract: An optical cable is embedded in a printed circuit board using a MEMS mirror to steer the photonic signal from the surface of the board to the optical cable embedded in the board's interior. The photonic signal is conducted from the surface to the embedded mirror by way of a vertical optical via. Such optical vias are used as well for coupling phctonic signals between plural optical layers formed by plural flat optical cables. Some or all of the plural flat optical cables are internal to the printed circuit board. Other steering devices may be used that provide equivalent function to that of the mirrors.

Abstract: A chassis and associated telecommunication circuit card are disclosed. The chassis has heat dissipation and flame containment features while accommodating a high density of the circuitry cards. Embodiments include an inner housing with a double-layer middle floor dividing the chassis into top and bottom chambers. Each layer has partially aligned slots, and an air gap is provided between the two layers. Embodiments also include a double-layer mesh cover with an air gap existing between the two mesh layers. Projections and grooves are provided on the inner surfaces of the inner housing to receive circuit cards having a guide on one edge and a fin on another.
