Abstract: A cable such as a server cable may have a tapered termination portion that when connected to other information handling system components reduces the loss of signal between the cable and the information handling system component. A method of making a cable with a tapered termination portion comprising heating a wire having an end and a body portion, the body portion having a first diameter; pulling the end relative to the body portion, for example with a clamp coupled to the end under tension, to obtain a location between the end and the body portion having a second diameter smaller than the first diameter; and cutting the wire at the location.

Abstract: Traces on a PCB can be spaced closer together than in conventional layouts, which previously required the pair-to-pair spacing for the high-speed differential stripline signals to be at least 5H if the signals are originating from the same source and 7H when the signals on two pairs of transmission lines in the traces originate from different sources. Traces may be spaced closer together when, for example, a ratio of the core height to the prepreg height of the printed circuit board is approximately equal to one. Traces may be spaced closer together when, for example, a ratio of the trace spacing distance to the core height distance is less than approximately one. By implementing one or both of these design rules, printed circuit board layouts can be designed, and printed circuit boards manufactured from those designs, that have an intra-group spacing between the first pair and the second pair measured at a point at which the first pair is closest to the second pair of less than approximately five times the prepreg height (the limit for previous printed circuit board designs).

Abstract: In one or more embodiments, a circuit board may include a trace pair and a serpentine region of the trace pair, which may include: a first subregion in which the first trace includes a first portion that has a third width and a first length and in which the second trace includes a second portion, at least substantially parallel to the first portion, that has a fourth width, greater than the second width, and a second length; and a second subregion, adjacent to the first subregion, in which the first trace includes a third portion that has the third width and a third length and in which the second trace includes a third portion that has the fourth width and a third length, different from the second length.

Abstract: A cable of an information handling system may include a first signal wire, a first drain wire, and a plastic sheath enclosing a volume having at least the first signal wire. To reduce mechanical stress on the cable and the drain wire, the drain wire has a ratio of length along a first axis and along a second axis perpendicular to the first axis that is not equal to one. When bending a cable away from a first axis parallel to the cable's thickness defined as the longest dimension or towards a second axis that is perpendicular to the first axis, the top surface of the wire in the bend undergoes tensile stress and the bottom surface undergoes compression stress, and the non-equal lengths along the two axis reduce the effect of the compression and tensile stresses.

Abstract: An apparatus includes an interface with a plurality of channels; a multiplexer coupled to the interface and configured to couple transmit circuitry to a first channel mapped as a transmit path in a channel configuration and to couple receive circuitry to a second channel mapped as a receive path in the channel configuration; and a controller coupled to the multiplexer. The controller may be configured to perform the steps including determining a figure of merit of at least one channel of the plurality of channels of the interface; determining the channel configuration mapping transmit and receive paths to the plurality of the channels of the interface; and controlling the multiplexer to couple transmit circuitry to the first channel mapped as a transmit path in the channel configuration and to couple receive circuitry to the second channel mapped as a receive path in the channel configuration for dynamic channel swap(s).
