Abstract
In some embodiments a Universal Serial Bus cable includes a first differential pair to transmit bus signals, and a second differential pair to transmit bus signals in a same direction as the bus signals transmitted by the first differential pair. In this manner, a bandwidth of the Universal Serial Bus cable is doubled in that same direction. Other embodiments are described and claimed.
Claims22
A controller, comprising:
- a transmit block wherein a direction of data on a first differential pair and a second differential pair of a cable is configurable by a Basic Input/Output System, and
- in response to a configuration of the direction of data in a same direction a bandwidth of data is to be doubled.
A system comprising:
- a host device;
- a client device;
- and
- a cable to be coupled between the host device and the client device, wherein the client device is to communicate the host device about itself using a communication path of the cable, wherein the cable includes a first differential pair and a second differential pair and a bandwidth of data across the first differential pair and the second differential pair is doubled in a same direction, and is greater than a bandwidth of data on the communication path.
A cable comprising:
- a first differential pair and a second differential pair,
- wherein a direction of data transfer on the first differential pair and on the second differential pair is the same, and a bandwidth of the data transfer is greater than 10 Gbps.
A cable comprising a first differential pair and a second differential pair, wherein the first differential pair and the second differential pair are to implement a dual simplex connection.
