Introduction to usb 3.1 cable
May 26, 2017| Introduction to usb 3.1 cable
USB 3.1 is the latest USB specification, the specification by Intel and other large companies initiated. Compared with existing USB technology, the new USB technology uses a more efficient data encoding system and provides more than twice the effective data throughput (USB IF Association). It is completely backward compatible with existing USB connectors and cables.
USB3.1 compatible with existing USB3.0 software stack and device protocol, 5Gbps hubs and devices, USB 2.0 products.
Intel has Thunderbolt technology also welcome USB3.1 standard forming.
USB 3.1 contains most of the features of USB 3.0
USB 3.1 as the next generation USB transfer specification, commonly referred to as "SuperSpeed +", will replace USB 3.0 in the future.
Standardize the course
November 12, 2008 After the launch of USB 3.0, SuperSpeed brings 5Gbps high-speed transmission performance, additional 5V / 0.9A power supply. The USB Implementers Forum officially announced the launch of a new USB 3.0 enhanced version (USB 3.1) on January 6, 2013, as the transfer rate requirements were increased and the hope of boosting power supply. July 31, 2013 announced the official launch of SuperSpeed 10Gbps, December 3, 2013 USB 3.0 Promoter Group officially announced the birth of USB 3.1. To June 2014 Computex Taipei 2014, ASMedia first official display of native USB 3.1 chip, to achieve SuperSpeed +, that is, SuperSpeed 10Gbps rate.
Interface specification
Usb 3.1 has three connection interfaces, namely Type-A (Standard-A), Type-B (Micro-B) and Type-C
Standard-Type A is currently the most widely used interface, Micro-B is mainly used in smart phones and tablet PCs and other equipment, and the newly defined Type-C mainly for the more thin, more slim equipment.
Type-C significantly reduces the physical appearance, more suitable for short and thin handheld devices, Type-C will replace the Micro-AB-type connector (support USB device directly on the pass, do not need to master the system involved) Will also replace the general Micro-USB connector, Type-C imitation Apple Lightning connector, positive and negative can be used normally connected, more ideal than the existing Micro-USB, Micro-USB although to prevent reverse anti-fade mechanism, but Positive and negative can be connected to the benefits, better than to prevent reverse, dark conditions can be successfully completed wiring. In addition, Type-C also has improved electromagnetic interference and RFI mitigation characteristics.
